The water is the source of the life.Along with life the exaltation of the
level, people of life is changing toward the middle-class family type from WEN
BAO3 XING2.Improve the drinking quantity is already the urgent target that large
people's crowd pursue, is in recent years particularly, the drinking water consume
to have already been accept by many citizenry, consuming the market more and
more big, the market competition is also very vigorous.But each kind of waters
all have it each from of characteristics.What water should to know drink, should
have to each kind of water a probably of understanding.Underneath, introduce
toward everyone once a few main drinking water that promote on the market currently:
Drink the purified water drinks the purified water with match the water of
the living drinking water health standard as headwaters, adopt to distil the
method, the electricity seep method, ion exchange method, anti- permeate the
method and other appropriately process method do away with the water that the
aquatic mineral quality, organic composition, harmful material and microorganism
etc. processes to make into.According to process the craft dissimilarity, drink
the purified water to also be called the distilled water, pure water of the
water, space...etc., is main product of the drinking water market.The above
drinking water of 90% produces the business enterprises to all produce the purified
water.The purified water fluid matter is pure, transparent, eating good.Because
the purified water has no the mineral quality, the fluid matter be partial to
sour, so be the life to the purified water in the only one drinking water to
the human body health whether have the influence, have been topic that expert
issue.
Drink the natural mineral spring drink natural mineral spring is gush from
a nature of or was make public by artificial of did not be subjected to polluting
of underground mineral water, imply the certain quantity mineral salt, little
chemical element or the carbon dioxide airs, under the condition of usually,
its chemistry composition, discharge, water temperature etc. the dynamic state
is within the scope of natural motion opposite stability.The mineral spring
implies the more mineral quality, the some and particular chemical element has
the function of health care to the human body healthily.The mineral spring of
the region of Shanghai takes out from the deep well, to enrich the mineral spring
with Strontium(Sr) and be partial to Si sour is characteristic.Because groundwater
of Shanghai in the ion of Na , the chlorine ion content is higher, the aqueous
degree of hardness is also high at the same time, making the eating of the mineral
spring been partial to up salty, if heat the boiling words, will still produce
the mineral quality to precipitate, the fluid matter appears the muddy, can't
make some consumers accept.
Mineral quality water
The mineral quality water increases a little amount mineral to turn the chemical
element to make into on the purified water foundation.The emergence of that
type of water mainly aims at the purified water not to contain the mineral quality
and drink over a long period of time healthy to the human body disadvantageous
this ory breaks but develops.Along with the turn worse of issue, the type's
water contain the trend of the further extension.In recent years, have not a
few purified waters production business enterprise to produce the mineral quality
water at the same time, with the orientation the dissimilarity consumes the
demand of the community.But have no nation the standard because of the mineral
quality water, its quantity is only ability from business enterprise oneself
establishment the business enterprise standard to control.But the mineral quality
water that different business enterprise produce, its mineral turns the chemical
element category different from contents are all.Some business enterprises even
add the chemistry to try in the water directly, the concentrated liquid of the
business enterprise usage background unidentified mineral quality that also
have, these safeties and usefulnesseses that increase the material did not carry
on the argument, content of how much also have no science according to.
The spring water( natural water) Shanghai is on the market the spring water(
or call the natural water) of the sale is draw from the river, Guang on taking
to pollute the less of river, lake in or the water of the underground, filter
through depth, make into after disinfecting the processing.This water implies
one mineral quality of the fixed amount, but the content is is low in the mineral
spring, can not reach the index sign of the mineral spring national standard
provision, so nothing of is a mineral spring.And among them some minerals quality
content is also unsteady.In addition to local business enterprise directly selling
in Shanghai, these waters are mostly after Shanghai produce the business enterprise
to entrust the region to infuse to pack, the above sea produces the name of
the business enterprise to carry on the sale.This water because of producing
the place in the another province City, Shanghai City don't as to it's the execution
allows to produce the certificate management and directs to make selective check.The
product quantity mainly from produce the business enterprise to request to carry
on the control according to the business enterprise standard.
The choice of the drinking water of ¡î
Choose and use the drinking water, should notice following several aspectses:
1.Whether check a cover of the hogshead water seal completely or not.A cover
does not seal completely, the water is easily pollute by germs.Especially in
summer, the bucket covers the easy occurrence to loosen to move.Can try to revolve
a cover by hand, see a cover can turn to move.Or pour bucket put in a short
while, whether an of observation has the exudation of water or not.Explain the
bucket that the cover does not seal completely if have the exudation of water,,.
2.Whether fluid matter in the careful observation bucket is clear or not,
whether suspend the thing.Explain that the fluid matter is subjected to the
pollution if discover to have already suspended the thing, foreign body or s
in the water in the bucket muddy,,, can't drink.
3.Choose a water for pack as far as possible, an usage time is long, will
slip not only inside the wall, depositting the bucket of the mineral spring
especially, producing the mineral quality to precipitate easily inside the wall,
not easy and pure clean, will stir up the germs.Observe a wall, can't appear
the green weed.Discover the green weed, explain the water already drive the
microorganism pollution, can't drink again.
4.Taste a water.The normal water should have each each kind of water from
the normal eating, sometimes there will be the slight ozone flavor, this is
normal.Can't drink again if have other strange smells or the plastics flavor,,.
5.Notice the date of production of product, drink the product produce in the
near future possibly.Once a Kaifeng drink, should drink to finish as soon as
possible.General on board barrel water in the drinking, drink to expect shouldn't
over a week, otherwise, fluid matter easily be subjected to the air the pollution
of the germs.
6.The Water Drinking Machine should place in clean and well ventilated environment.Periodically
use to disinfect the liquid to clean the disinfection, assurance Water Drinking
Machine hygiene.The mineral spring and spring waters should keep at cool, avoid
the light, avoid the sunlight irradiation.Because under the function of the
sunlight, alga will breed quickly, causing green weed appear.
The related chain connect
The main technique request of the drinking water
Drink the national standard of purified water difference for GB17323-1998
¡¶ bottle packs to drink the purified water ¡· and GB17324-1998 ¡¶ bottle packs
to drink the purified water hygiene standard ¡· .All ruled the sense organs index
sign, the physics and chemistry index sign and microorganism index signs in
those two standards.
Feeling view index sign:The sense organs index sign includes the color degree,
muddy degree, smelly and flavor, and can see without the aid of instruments
4 of thing, is basic request of the purified water.The color degree should not
over 5 degrees, and can not have other different colors;The muddy degree is
not over one degree;The just like flavor, the difference is smelly and can see
without the aid of instruments the thing.
PH value:The pH value is to mean the aquatic and sour alkalinity.The purified
water produces because of producing the craft reason of water be partial to
the acidity.The pH value scope is in 5.0~7.0.
Electric conductivity rate:The electric conductivity rate means the pure degree
of the purified water, is the characteristic index sign of the purified water.The
electric conductivity rate is more low, explaining the water more pure, the
miscellaneous quality in water is more little.The electric conductivity rate
is in the standard provision purified water should 10 ¦Ì S/ cms of ¡Ü .
The high potassium manganate consumes the quantity:The high potassium manganate
depletion quantity mean the 1 L water in the revivification material the oxygen
milligram that consume while was under certain condition oxidize by the high
potassium manganate number, the content of the organic compound in its main
reflection water.The high potassium manganate consumes the quantity more low,
elucidation the organic compound in water is little, pollute little.Some disinfection
liquids remain and also will make the high potassium manganate consume the quantity
to increase high.The high potassium manganate consumes in the purified water
quantity should 1.0 mgs/ l of ¡Ü .
Swim to leave the chlorine: pure aquatic mainly swim to leave the chlorine
is the bucket cleans the ill success, making contain the chlorine disinfection
liquid to remain to resulted in chemistry pollute in the water.Standard the
provision swims to leave chlorine should 0.005 mgs/ L of ¡Ü .
Lead, arsenic, copper:The lead, arsenic, copper is the harmful metals chemical
element, will result in hurt to the human body health, should be more low in
the water more good.Standard provision lead ¡Ü 0.01 mgs/ L, arsenic ¡Ü 0.01 mgs/
L, copper ¡Ü 1 mg/ L.
The germ falls the total amount:The pure and aquatic germ fall total amount
is express that the purified water be subjected to to the pollution extent of
marking.Standard provision, the germ falls in the purified water total amount
should 20 cfus/ ml of ¡Ü .
Coliform:The main source of the coliforms is a person the raise excrement,
so that index sign is the excrement pollution index sign to evaluate the health
quantity of the purified water.Standard provision purified water in coliform
should 3 MPNs/100 mls of ¡Ü .
With the result that germ:With the result that the germ means and would cause
mankind the paroxysm germs, is mainly a surname germ, ambition congratulate
surname germ, golden color staphylococcus of sand and dissolve the guts streptococci
in the food.Can not check in the standard provision purified water with the
result that germ.
Fungi:Pure and aquatic fungi mainly is be subjected to produce the environment
in the fungi of pollution or bucket don't be pure to clean to result in after
are open-air deposit the pollution.The fungi will produce the toxin, resulting
in endanger to the human body healthily.Standard provision purified water in
can not check a fungi. |
