Core Tip: Current Situation and Confusion of Six Drinking Water. First, there is no water to drink; Second, you can't drink water; third, you can drink it unsanitary; fourth, it is unsafe; fifth, it is safe and unhealthy; sixth, it is unhealthy.
Present situation and perplexity of six drinking water. First, there is no water to drink; Second, you can't drink water; third, you can drink it unsanitary; fourth, it is unsafe; fifth, it is safe and unhealthy; sixth, it is unhealthy.
It is also very serious to have water to drink, which is also the focus of water improvement and water control in our country. Human activities, industrial and economic activities, including the pollution of surface groundwater caused by our geological disasters, including the nuclear radiation in Japan, have certain harm to our drinking water. There was a media report on the dialogue between the Yangtze River and the Yellow River. There was a detailed data analysis on the pollution degree of these two rivers, and 60% of the water in the main stream of the Yangtze River was polluted. The Dianchi Lake in Kunming is polluted by algae, and the polluted water cannot be used as drinking water. If the pollution continues, our water will become increasingly scarce.
Third, it is unsanitary to drink. Most of this situation exists in rural areas, rural water improvement level, urban-rural fringe and economically underdeveloped areas. This reference standard is around the standards promulgated by the Ministry of Health, which is verified according to national standards. If it meets the standards, it will be hygienic and safe; if it fails to meet the standards, it will be unsanitary and unsafe. Now how much water we have can meet the existing standards is very stressful. Here I say four aspects. The first one is that it can't meet the hygienic standard of drinking water, but it needs to be drunk in order to survive; The second one can not meet the hygienic standard of drinking water, and has been drinking like this since ancient times; The third part of the economically underdeveloped urban areas should drink tap water if it does not meet the standard; Fourthly, when the surface water is deteriorated by seasonal water sources, the quality of urban tap water is not up to standard.
We are now continuously polluted by Songhua River, Taihu Lake and other places, and we all know the pollution of secondary water supply tower and pipe network. These problems are drinkable, but unsanitary, which means that we can't meet our living standards.
Fourth, health is unsafe. The number of testing items in the new national standard has increased to 106, which is consistent with the standards of the World Health Organization and international standards. It will take time for us to make our water supply meet our standard requirements; In view of the current drinking water standards, the testing ability is backward and the testing items are not comprehensive, so our drinking water testing means will not work; The tap water technology is backward and needs to be transformed. This will take some time; Implementing standards and implementing standards; The speed of pollutants exceeds the speed of standard revision. As we all know, our standards have not changed in 20 years, and we don't know when the standards will be revised next time. However, although our pollutants have been basically controlled, our pollution rate is very fast.
At present, another international organization is studying the harm of various disinfection by-products to human body, and all of them are tested according to our current 106 standards. In this case, it shows that we human beings have paid attention to disinfection, instead of disinfection without diarrhea, it will create new potential safety hazards after disinfection. We may control it better in this respect, that is, the quality and hygiene are unsafe.
Fifth, safety is unhealthy. How to understand it? We can share the development history, course and trend of human drinking water. When we just had people on the earth, we drank water to survive and quench our thirst. But after we moved to the city to live and live, we introduced water into the city. If we develop again, the water introduced into the city can't be drunk, which will lead to hygiene. Like today, there are many safety problems, heavy metals, pollutants, etc., about hygiene indicators.
Safety is not enough. With the improvement of people's economic level, when our demand for quality of life increases, we should put forward health. I am not only safe, but also promote health after drinking water. Therefore, healthy drinking water is another step on the basis of safe drinking water. The purpose of health is to live longer and improve the quality of life, which is an inevitable trend.
What are the phenomena of safety and unhealthy? One is natural mineral water, and the other is a school of thought. The first is to propose natural mineral water, pure water is not as healthy as mineral water, and the second is the research results of international organizations on medical mineral water and disease efficacy. Prove that many medical mineral waters can achieve health care and treatment effects; The third is the research school of health in the field of nutrition; The fourth is the research school of water and life sciences at home and abroad. They put forward that water is not only safe, but also that the molecular structure of water will change with the existence of minerals and trace elements. It is the academic debate of these four schools that puts forward safety and health. Of course, this is also a process of debate in academic circles. Like natural mineral water, it is an indisputable fact for human health. If there is no polluted natural mineral water, it is worthy of everyone's respect and trust.
Sixth, health is not standardized. There are many industries, many varieties, endless academic debates, uneven quality, serious waste of water resources, lack of industry standards and irregular market, which are all non-standard phenomena of our health.
To sum up, the development trend of healthy drinking water in China is mainly based on tap water supply in urban and rural areas, which is the key development of the country, and various water supply forms will coexist. All of us here have a bright future. I wish that the development of various drinking water science and technology and the formulation of standards should focus on drinking water and health, and promote the healthy life of human beings, and truly put people first.
