The importance that is the human body life structure constitutes the part, the water goes to close the importance in the people's life.

Therefore, from the water but the problem for cause is then and particularly the stirring concern.Concerning the issue of the purified water also just current numerous among thoses of problem of water.

The drinking is cognitive and confusion, is the backset that the purified water contends for the output source modern people to know to the water, the drinking market mislead and the drinking science studies the regret of the some aspect is a current drinking of creation cognitive and confusion and the purified water contend for the source.

The ancients is to is the water" whole"( aqua) to treat, but the modern people stand alone the drinking to is divided into" dissolve the quality" and" melting agent"s, the former emphasizes the function of the aquatic mineral material, returning the function that the knot is the mineral material purely the function of the water, thinking the mineral quality category in water only more many more good, the content is more high more good.( this is the mineral to turn the background that water appear recently)And then but over-emphasize the function of the melting agent of the water.( pure H2O)Many persons think that drinking only is for quench thirst, but neglected the nourishment function of the water.It include the nourishment and" health care" in the drinking function, contain the very deep life science in the drinking process.The food take drink as first, Ming Dynasty Lee, Jean of hour, is in ¡¶ this grass outline ¡· the head that list as the water each.But the modern people neglects gradually and thin forgot the water to the health care, curative effect function that the healthy person and patients should have.

In addition, because our understanding to drinking water is little and studies little, plenty more" blind area" in drinking water study realm.Many problems are still not clear, also is cause the current drinking cognition confusion and the purified water contend for of a reason.

Since many years we notice the living creature body research of the outside water only, but neglect the research of the living creature body internal water.With human body for research of corpus, can chase the humidity as water outside the body and body internal waters.Currently to the water study all concentrated outside body water of realm in, for example resources of water, water conservancy, hydrology, water engineering technique, the water environmental protection...etc., but distribute, exercise to the body internal water, structure, function, know that the water, the research water then exists many blind areas and blank from the cell level, the molecular biology level especially.

The water not only rise the material inside the body to transport with the medium function, but also participates the big member structure of living creature directly, the big member of water and living creatures completed the material metabolism, the energy metabolism and information metabolisms of the human body together.Water and decrepitude, life span, immunity, metabolize to have the direct relation, we study to existent and 70% material of water inside the human body very few.

Why once purified water appear, purified water be welcome among the market the purified water originates the abroad, the development( point to develop the speed and develop the scale) is in the domestic.Why the purified water is in domestic short and shortly how many years the development is so quick, can the market accept?In addition to the business factor, have more is people to expect to" clean water";From various newses of" loose HUA JIANG SHUI3 at pollute"," the Pearl River water is pollute"," too the water of the lake is pollute"," some follow 512 headwaterses of the sea city in 300 be subjected to the pollution"...etc. that the medium flow out to appear continuously.

Arrive to counterfeit the false and inferior mineral spring to flood the market in great quantities, make people to water of" health" put forward the question with" safety" continuously, the crowd who add the life quantity raises continuously, the ego cares the to build up of the consciousness, becoming to the need of" good water"," high-quality water"," clean water".Purified water exactly because etc. from the craft, technique, series clean water equipments the aspect processes towards ising carry on by polluting water and running waters deeply, the aquatic heavy metals, three methanes of ± , organic matters, radio materials, microorganism...etc. harmful, poisonous, have the strange smell thing the big part to throw away, remove these pollutions material to direct and latent bane of the human body health.Removed the consumer to the dismay that drinking water pollute, satisfy the demand of consumer to" clean water", thus very quickly produced bigger" the market effect".

Why today produced the question purified water to the purified water to just publish again, just head for prosperous and period, why today not a few person to purified water whether is" trust water"," healthy water"," high-quality water" to put forward the question again, the purified water turns into the drinking water from the beverage water is one of the main reasons.

The purified water just was appear in the concept of a market still" beverage", later along with the emergence, thorough market, thorough family of the hogshead water(5 gallons of), become the people's usual drinking source, the purified water turned into a kind of" drinking" from a kind of" beverage", particularly was the quality piping of cent that some city carry on to keep drink water supply works, use of is all the manufacturing craft of the purified water.

We must peg out the different from" drinking water" is two concept of" the beverage water".The beverage water is selling the net to order for passive sell, the consumer is main to satisfy to quench thirst at the time, is not the necessity of everyday.But the drinking water is a public necessity, over-emphasizing in the public-spirited property, must drink everyday.Be the drinking water United Nations health organization contain strict meaning, namely person from be born 70 years old, average everyday drink what problem can't 1-3 kgs serve as.Use to keep off the nature to belong to sex thus, and the purified water of the pure but again pure non- state of nature processed out by science and technology drinks every day, drink and can appear the trouble over a long period of time, the people are not from produce the question to the purified water.In addition, the purified water produces the principle that the craft characteristics disobeyed the stanza water.

The our country is one of 13 poor waters nations in the world, the resources of water is very short of.But in the process of purified water take off salt, need 3 ton raw waters and then can produce one ton product of, have a great deal of raw water" waste water"

Eject.Wasted a great deal of precious resources of water.

Science understanding purified water 1, know from the Epidemiology epidemic research method of purified water much from in the great universe environment, learn with the macro view covariance, the comprehensive method and whole thinkings study this kind of social macro view of problem, the understanding problem investigation the method combines again the laboratory to study a certain problem in the meticulous and tight Îö because of method, would be more overall, more science.

Many nations( include a lot of research units of domestic) and international health organization, all report the common characteristics of the healthy personnel of longevity crowd that world" the longevity village"," have no cancer village" live once and successively, discover these regions often are all the year drinks the good water, but these good waters all have the same characteristics:(1)Don't imply the poisonous and harmful material;(2)Have the certain degree of hardness and mineral qualities;(3)The humidity son regiment is small;(4)The PH of the water the value presents the tiny alkalescence;

Over a long period of time the healthy condition that the prevention medical science in China science hospital drinks the mineral spring crowd that contain the mineral quality's have another to the west of ÉÂ , the river south carries on the inquisition, the expectation life span that as a result discover that crowd checks against the crowd than the soft water that nearby and living condition near to but drink the mineral quality the less 3 years old in height, old 5 years old of average death age, men and women's primary school livings high 3 rices of Àå of of the height difference and 5 rices of Àå , the weight is many 2.7 kilograms of and 4.6 kilograms.The cardiovascular disease expert of our country wins academician's professor Wang of the section hospital to also point out, drinking one of the reason with little soft water of the mineral quality, is results in the artery gruel kind harden over a long period of time.

In the United States and Canada to often the year drinks the crowd of the soft water( degree of hardness below 50) to investigate, the death rate that discover the cardiovascular disease is 10.1% higher than the crowd of drink the hard water, detection in 253 inquisitions of town of 1969-1973 years of England, the soft water region is cardiovascular to die the number higher than the hard water region 10-15%, put forward most ideal degree of hardness' is about a 170 mgs/ L in the report or so.As a result standard clear statement provision of the latest( version 5) drinking water fluid matter in Canada, the soft water can't be the drinking water directly.The degree of hardness that also rule the water wants to keep more than 60 in European common body drinking water fluid matter standard.

Can say, many national purified waters can't be the drinking water to have already become the hard conclusion abroad.

2, know the purified water study" drinking and healths"s from the medical science animal experiment research paper

Of relation, still take the strict biology experiment result that professional personnel do as to have most the conviction.

The former Soviet Union the scholar once did the degree of hardness of water different steps degree on trial with the small white rat, experimenting the steps degree( mg/ L) water that distinguishes to 0( distilled water),50,100,250,500 and 1000, was keep by hello growth for five month the metabolism experiments the result enunciation, the result is worse is 50, the elucidation water degree of hardness lead high or lead low to the animals growth growth and metabolize all not good,7 among thoses experiment the set to take the distilled water set as the most bad, the animal feed consume the quantity, animal feed to all take the distilled water set as in the quantity( direct measurement) that the energy consumes to eject the mineral material in the quantity, urine tallest.Explain from this experiment, a lot of drink the Human body body of the purified water to have the soft felling of hair over a long period of time, is to result in the mineral quality inside the body and other nourishment materialses run off speed with purified water easily relevant.

The IDM living creature technique graduate school of Peking carried on the nature to return to the medical science biology experiment of return the systems, such as water, purified water, running water and the mineral spring...etc. in 1996, this is the local report currently at the earliest stage different drinking water fluid matter to the system biology experiment of the healthy influence.Experiment all from professional personnel, request according to the biomedical science method strictly, choose use standard experiment animal, have repetition etc. the condition complete of.

Develop from the growth, the anti- disease and anti-s meet an emergency the various biologies experiments such as ability, cholesterol-lowering function and metabolism etc. result to relatively discover, have another item experiment in is most bad with the purified water set, return to return set of water is best.

For example return to return the set of water to compare the purified water set indoors under the low temperature condition the survival rate raises 10%, the red cell quantity(1012/ L) raises 9.7% in the blood index sign, the white cell quantity(109/ L) raises 8.2%, the hemoglobin quantity( G/ L) raises 4% etc..At and the plant growth growth and decrepitudes that half-hardy center consociation of south agriculture university of Ȼ carry on experiment, and the microorganism suppress the germ experiment, the goldfish farming etc. numerous biology experiment, also obtained the same conclusion:The purified water set is most bad.

Medicine department university of Shanghai six Jui-fang professors wait for someone the relation to various mineral quality in water carries on just to hand over the experiment, in the elucidation water the mineral quality and the human body health close, explain that while water is losing all mineral materials, also lost the immunity function of the water.

Fresh proved clearly from the biomedical science experiment report there has been at home and abroad from the conclusion that the human body experiment gains, is also a hard water more more healthy than soft water, the hard water tie lived the harmful composition( for example lead, ïÓ , chlorine and fluorine), lowering to their absorption, or is the mineral quality of the hard water is mainly magnesium and calciums, provide the nutrient that exertive harmful function of the arrestment poison need.Therefore imply the certain degree of hardness and mineral quality, tiny and alkaline waters beneficial to the growth growth and healths of the animal and human body.

3, know the purified water from the dietetics angle from the dietetics angle, we emphasize the food to can't speak the " digest" and" absorb" only in the nourishment material, even wanting to account the nourishment material in " sink to accumulate" in the body, the nourishment material absorbs in the body good, but run off quickly is also not a good phenomenon.For the sake of the study water medium nourishment material to these solid forms nourishment material in the body of" absorb" and the influence of" sink to accumulate", the IDM living creature technique graduate school of Peking once does such nourishment metabolism to experiment, using three kinds of waters( running water, purified water, return to return the water) ËÇ hello standard experiment animal( big and white rat) respectively, three experiment an animal feed of nourishment constitute similar, the protein biology effect price( BiologicalValueBV, BV= RN/ DN) result that big and white rat metabolism experiments the measurement:Take the running water set as the matched control(100%), then return to return a protein of water biology effect price to compare the running water to raise 17.9%, but the purified water set compares the running water set to lower 9.3%, explain that often drink the purified water and will lower the food to make use of in the nourishment material( protein) and body inside sink to accumulate.

The Doctor of Fox puts forward impressively in ¡¶ health and waters ¡· one book as follows standpoint:" The water that drink to be pollute and will endanger our health in addition to brines( namely pure water)".

4, point out from the angle understanding purified water modern quantum chemistry knowledge and standpoints of tiny view and second tiny view, the water is more pure, the humidity son depends the pole function, establish more the line regiment coagulates the structure of ̬ , namely the water presents the big member regiment appearance, the nuclear magnetic resonance measure the diagram seems to be very the breadth.The parties concerned that wins the section hospital measures with the hydrogen table result is:It is 26.9 Hzs, distilled water that nature return to return the water as 8.8 Hzs, purified water is a 36.8 Hzs.Test to find out the result and regulation and abroads the report is look like.The member regiment of the water is more big, seeing the aqueous life vitality more weak from the water physiology angle.

Moreover, the human body dietetics in addition to speaking the nourishment balance, should still speak the sour alkali balance.The person's body fluid is a tiny alkalescence, the mankind are several thousand, several ten thousand yearses come to all is natural water but existences that drinks the tiny alkalescence, a tiny ecosystem of bowel area system inside the environment, body inside the body all adapted the tiny and alkaline water, chopping round to often drink the water of present the tiny acidity once, can result in body inside the liquid environment of unwell should, the breakage of the tiny ecosystem environment inside the body, these are all to should study and advertent problem.

In fine from big arrive the heavenly body, small arrive the material of the member, atom level, all have inside outside of" unify" and" balance", the water also should have this kind of natural regulation, the factitiousness breaks this kind of to" unify"

Will produce the negative effect to the human body healthily with" balance".Do not stand alone of from treated the function of the mineral material in water on the other hand, also don't want that the list discussed the mineral quality that human body need from the quantity angle to come from the water, is still from the food.

5, know the purified water from the living creature experiment modern age biology of research and experiment mostly from the plant start, develop the animal gradually, then arrive the mankind.For example the progress of the modern genetics, begin from the ÃÏ fruit fly experiment of eight years garden pea experiment, the root of Ħ¶û of the virtuous ¶û .Also begin from such as the gram ¡ technique again to duct into the anti- insect gene in the corn, till now gram ¡ sheep etc..The glacier jelly the soil graduate school in the Chinese science, hospital carries on the plant that the plant experiment as a result discovers the glacier water's grow with the glacier water, running water and the yellow river waters good, the yellow river water is most bad, drinking the glacier water continuously two after month, the human body blood fat has to lower.From a great deal of plant experiment that our big and southeast company( once organize 5,000 ginsengs and experiments) in graduate school, Zhejiang do in can see:The purified water brings disadvantage to the most plant growths and growth.Explain the good water to not only be advantageous to the human body health but also be advantageous to the plant growth growth, this is the biological phenomenon that the life body has together.

The beneficial shortage of ³z that it contend for of purified water takes a comprehensive view of the whole personal history for develop, in the development of each science, all being filled with the different academic standpoint, issue between each different school of thought.Practice the occurrence of prove science issue and carry on to become the natural science development to have most the life vitality, the most creative motive.

Bear from that day from the purified water, to the purified water it contends for have already start.The whole country begins from Shanghai City to the controversy of the purified water to teach ί to a document of the primary and junior high school in 1997:" The primary and junior high school living just be placed in the growth and intelligences to develop the stage, plus the sport but creation to exhaust many have no the machine salt and the mineral quality, if drink the purified water over a long period of time, the disadvantage grows up in the health that primary and junior high school living, resulting in the bad influence." At the same year the July, an enunciation of a report" harmful generation person of purified water of health" of the youth report of Shanghai, is also a motion that causes the national purified water business enterprise.On April 24 in this year, national purified water profession triumvirate farmer the mountain spring declare:" Purified water to healthy not beneficial, from now on not the reproduction purified water but change for the natural water." This disaffection that declares to cause national and many purified water factories and send punitive expedition.This time both parties thick controversial" explosive" flavor, the motion face it widely, affect it deeply, at is all seldom seen at home and abroad.

I think that relevant purified water it is necessary that it contend for, also is beneficial, is also inevitable, the issue will certainly produce a truth after.Contend for through a purified water, can strengthen consciousness and universalities of consumer to drinking water, can push the healthy development of the purified water profession, more important can promote the research of the drinking science and go deep into.

In this" purified water" contend for can't depend the thinking method of the planned economy type, hope a certain authority section, a certain expert to give to draw a conclusion, more can't with" person many power many" come to body the truth place now.Contend for the medium academic problem concerning the purified water moreover, is also to should be used the science data by the academic group, experts, theory according to elaborate with science language each from see.At present" purified water" contend for, the business enterprise field, journalistic circles fries to do excessive, the scientist participates directly little.I suggest, the academic circles academic issue and business enterprises fry to do the behavior and must separate, not the important cause fries to do to the business enterprise, news of stop but stop beneficial academic issue.

Must insist that science didn't forbid the area, science to have no the principle that the peak, science has no idol in academic realm, construct a kind of strong but loosen each academic atmosphere that express the one's own opinion, free argument, the democracy discussion and obeys the truth, real attain to resolve the science problem with science attitude and science methods.

Concerning released" the bottle packed to drink the purified water nation standard" on April 21 in 1998 to the suggestion nation of the mark ù¨ modification that the bottle packs to drink the purified water nation.This standard of release for the push, norm just the bottle that rise pack the pure drinking water profession contain the preface development rise to push and guarantee the function very greatly.

But the standard also has its dynamic state and time limited efficacies, analytical means along with exaltation and sciences of science technical progress, people consciousness of perfect, standard general 3-5 years want to carry on complement and revise.Exist many shortage still in the purified water country mark currently, exist the not perfect place, for example:The China medical science meeting environmental hygiene cent meeting Tung enjoys well the chairman of committee also puts forward the purified water standard currently in some index signs exist" not scientific, insecurity" of place.

I think to pack the purified water country mark to the bottle to press certain procedure to carry on the emendation as occasion arise, and provide following modification suggestion:1," drink" to change for" beverage" in" the bottle packs to drink the purified water".

2, some index signs should BE in line with with international drinking water standard currently.Want to BE in line with the word technical term and the foreign drinking fluid matter standard first.For example, all did not appear one phrase of" the electric conductivity rate" in all foreign fluid matter standards, but the total solid of the adoption" degree of hardness( CaCO3)" and deliquescences means the mineral quality content in water.But" the electric conductivity rate" is the industry produces to use the water adopt of concept.

3, standard the establishment wants science according to.The PH value in water to human body the health is an important index sign.

The human body blood PH value scope is 7.3-7.45, the purified water PH be worth to 5-7, raining the limit value even low in the index sign that the acid rain pollute.(5.6)In the world there is no whichever nation specify such low standard, the thus low and sour value water is the drinking water of the human body to lack science of basis conduct and actions guide.

4, should the strict is strict, a breadth.Drink the fluid matter standard to compare with the abroad, in the purified water country mark existence should strict not strict, not wide phenomenon of that breadth.For example, the germ falls to amount in the purified water each small in be equal to 20, other than world national drinking water standards are all strict, foreign that this standard of many nation cancel.The harmful microorganism index sign is strict abroad again strict, the large intestine muck germ is each in the purified water standard 100 milliliters of small in be equal to 3, abroad standard and the our country then rule and can not check in the living drinking water standard of the new emendation.Moreover, swim to leave the chlorine( account the ml/ L with the CL) to settle to 0.005 to remaining in the country mark, exceed the analytical instrument sophistication, the accuracy settle so strictly, whether science, practical?

5, the conflicting place of purified water should take into the modification.For example the chloride can be equal to 6, the electric conductivity rate by all means over 10 uSs/ cm, but the standard request the electric conductivity rate is 10, the business enterprise does not know with which item for allow.

6, be the nation to drink the purified water water standard, should consult the nations and abroad forerunner of the drinking water fluid matter standard is basis, not one with industry use water, medicine use standards such as water and the beverage water etc. conduct and actions according to.

7, the standard wants to attain science first, particularly drinking water the standard is more direct is healthily relevant with human body.So nation the standard establishment should regard expert's community as principle, not take business enterprise as the corpus to participate.

At the same time the expert choose also should body now word" particularly" up, should with be engaged in the drinking environmental hygiene expert for corpus.

8, should with drink what kind of water for premise, then go to certain and consider the craft and equipmentses, not reverse to come over, taking equipments as or so our standard of premise to draw up.

At the same time, I also hope that the purified water business enterprise is on the original hardware and the technique condition foundations, using a little amount funds to carry on the reformation to the equipments, reserving the beneficial composition in water possibly, making product attain" pure" unify with" health".( the concerning the purified water skill change, I have another the article treatise, in order to prevent head for another mistake area from a kind mistake District)I think that most entrepreneurs all think to do some good matters, healthful matters for people.We shouldn't change this skill to see is a kind of" burden", and even should see is the development and progresses of the business enterprise, actually, local and not a few purified waters factory house has already started the skill change and expanded the new product currently, as above the sea postpones the medium purified water and gets especially the full distilled water hases already increased the mineral to turn the liquid, other pure factories of ÍÞ¹þ¹þ , Robust...etc. also start produce the mineral spring, this is also a kind of progress, hope at on the market see numerous purified water factories more up one floor of healthy water, make the thousand ten thousand real drink up" trust water".

To on the market lately- appear natural water, spring etc. the science meaning and standards of the product specify and also should lift up the agenda, in order to prevent appear after purified water of new market is confusion.

We should admit this actuality, the person's drinking water main current is a running water among nations, is also a running water in the future.The basic exit that solves Chinese residents' drinking water lies in the consciousness that grows the person, strengthen the headwaters of protection and pollution cure for good, strengthen the running water water factory technique reformation and science managements, improve to lose to go together with to take care of the net system, manage to clean in time in the center water tank, reduce to exterminate the running water to pollute two times, make the residents attain" qualified water"," high-quality water" from the fluid matter of water that the faucet come out, attain the advanced level of international fluid matter, attain the healthy demand standard of human body.

I think that the healthy water wants to match standard of following 7:00:1.Not material with any rightness human bodies poisonous, harmful and have strange smell.( value the organic pollutant particularly)

2.The degree of hardness moderation of the water, the 50-200 mgs/ L( account with the calcium carbonate) is proper.

3.Human body need to have the just right the mineral quality content.( the main consideration crowd is widespread to lack of often measure the chemical element)

The 4. PH value wants to present the tiny alkalescence.(7.0-8.0)

5.It fuse oxygen and two oxygen carbon content moderation( the deep solution oxygen «ð 6 mgs/ L in water)ses in the water.

6.The humidity son regiment is small.( the number of Hz mean)

7.The nourishment physiology function( such as water of deliquescence dint, permeate the dint, spread the dint, emulsify the dint and wash the dint clearly etc.) of the water want to be strong.

Today this kind of drinking market is confusion, is all temporary, in the future along with the test, discussion that study thorough and practice with contend for the Ãù , will make the water gradually understand, attain the consensus.

Author's brief introduction:Prof. LI3 ºZ XING is an expert of the our country water dietetics Öø , professional committee director of incumbent IDM living creature technique graduate school bureau chief of Peking, Chinese healthy drinking water.Many years be engaged in the water nourishment science research, and put forward" recedes to turn" science ories and" healthy water"s first among nations The system concept, be subjected to United Nations to value highly.
