To talk about drinking - drinking more than the perspective of five categories
From:City Biz Paper  Date:2009-04-03
| Sunlight, air and water on the Earth are human beings and other species of the three conditions for survival. Normal, the sun is visible or touched, the air is invisible, and the water is visible and tangible. On the current scientific and technological strength, the people want to change the sun, "sun drying" a change of air "Cigarette smoking" in mind, in fact, is not realistic. Only water, have our own choice.
This is how the election of water, how to choose science?
Choose the classification of drinking water, in the academic community is also a very hot topic, after a longer period of time in research and feasibility studies, experts and scholars from the drinking water needs to meet the people's level of drinking water and property, quality, drinking water production process such as point of view, summed up the "five categories of drinking water," the scholars generally agree that more scientific "classification of drinking water." This is March 22 this year, World Water Day theme of Chinese Propaganda Week "to implement the scientific concept of development, protection of water resources conservation" is each other.
Drinking water was the pyramid structure of five categories. Taki in the fifth category of drinking water to be solved are the questions people have water to drink. Now there is more than one third of the world's population in the dry and semi-dry status, and Northwest China, the proportion is higher still, "the mother cellar action" is to the situation of water shortage in the region and extensive carried out by "the public good."
In fact, the originator of the late nineteenth century in the water industry, is to scale, industrialization solutions to drinking water, the water problem. Along with the process of industrialization, water has become the solution to scale the size of the population of the principal means of drinking water. However, the traditional production process and the water should not the total elimination of some impurities in the water, in addition to frequently happened in recent years, water pollution of water sources, water quality degradation of the situation for people to question the safety of drinking water a wake-up call. Therefore the improvement of water production and water quality improvement has already been referred to the agenda of people above. At present, China has many cities are trying to start or dual water supply projects, at this point going on in Suzhou is a city at the forefront of one of the more.
The fourth category, are currently on the market for sale through the net bucket, straight drink machine, pipe machine, central water purification system water purification equipment and other home improvements from the initial filter tap water. Collectively referred to water experts such as water purifiers water. Water from water purifiers to some extent, solved the problem of drinking water for the primary filter.
Household water-purification equipment in accordance with the principle of job can be divided into two categories:
One is the activated carbon filter, then the net or bucket at the tap water purifier on many belong to the activated carbon filter can filter out the small amount of residual chlorine in tap water and impurities, but heavy metals, pesticide residues and other pollutants Absorption capacity of poor Moreover, the majority of activated carbon filters use one years later, no matter how much water has been, we can not reduce the chemical substances in the water. Such equipment on the water quality improvement is not obvious.
The other is membrane technology filter, using reverse osmosis method of water purification equipment, such as part of straight drinking machine, pipe machine, central water purification equipment to purify some more effective than activated carbon filter, but generally only get a little more than raw water quality drinking water well.
Bands further down the pyramid layer is going on in the third category of purified water. Although in recent years, there is continuing controversy over the purity of water, but from an objective point of view, pure water in the industrialization and standardization of production conditions, is indeed resolved to meet the people's health and safety, clean drinking water demands.
Common on the present market, "pure water", "pure water", "ultra-pure water," "distilled water", "magnetized water", "Sodium Water," "space water" belong to all areas of pure water. They are in line with the hygiene standards of living of surface drinking water sources, the use of distillation, electrodialysis, deionization, ion exchange, reverse osmosis processing methods, such as made the water go apart from minerals, organic components such as micro-organisms.
Of course, controversy about this type of water mainly comes from, although they go in the water except some of the above-mentioned material, but also go on the human body apart from beneficial minerals and trace elements, and its high standards and health standards for drinking water seems to have a certain distance.
In addition, the market add up to rely on artificial minerals as part of a mineral water system, many experts think, it should be attributed to "pure water" the area.
Better use of the water quality of rivers and lakes, such as one type of surface water, well water, stream water (usually referred to as mountain spring water, but from the perspective of geography, its sense is not really spring water), such as shallow groundwater, glacial water production of drinking water, referred to as natural water. Natural water with its natural property of water, strong activity, partly to meet the drinking water for health and were therefore classified as experts and scholars to the second layer higher-order type of drinking water.
However, such water in addition to water ice, are on the geographical classification of surface water, influenced by the environment, water quality stability of weak, natural water quality control has become an insurmountable bottleneck. If the water quality through artificial means to achieve the relatively constant, while the number of suspects would be unworthy of the name, but not the stability of the water quality control, then there will be a resignation, the taste of food by day. Since the water surface, the drop of its water quality of rain will probably have an enormous impact, then we drink the water and are not the same as yesterday, tomorrow would be like another, which has become a major the suspense. Therefore, the definition of natural water, so far, it does not have a country specific standards. |
