At present, the water purification products on the market mainly include ultrafiltration (traditional filtration technology, generally single filter element) and reverse osmosis technology. The water quality of Shunde’s industrially developed areas must use reverse osmosis (ReverseOsmosis) technology water purifiers In order to completely remove the chemicals in the water.
With the rapid development of modern industry, environmental pollution has become more and more serious, and the water sources that people rely on for survival have also been severely damaged. Many industrial wastewater and domestic sewage are directly discharged into rivers without treatment, and directly affect human health and Survive.
How serious is water pollution today? According to Professor Wang Zhansheng, a professor and doctoral supervisor of Tsinghua University, the deputy director of the Water Supply Committee of the Chinese Civil Engineering Society, and the chairman of the Advanced Water Treatment Research Association, people’s drinking water has great potential safety hazards. There are all kinds of pollutants in the source water, organic and inorganic, especially chemical pollution is increasing day by day. Existing detection techniques have found that there are 2221 kinds of organic compounds in water and 756 kinds of organic compounds found in drinking water, including 20 carcinogens, 23 suspected carcinogens, 18 carcinogens and 56 mutagenic substances. According to the existing drinking water standards, 900 million people in our country are drinking unsafe water, especially in developed industrial areas. What’s more, the current standards were formulated in the 1980s, which is far from the standards of developed countries.
It is understood that more than 99% of water plants in my country still use the conventional treatment technology 100 years ago. It is impossible to remove the chemicals in the water by using the conventional purification process 100 years ago to treat the current water. Chlorine, as the main fungicide in the traditional process of tap water, is becoming a new source of water pollution. The main hazards are: Chlorine has strong oxidizing properties, it will destroy the nutrients in food and hinder the body’s balance. It has a strong fishy smell. Chlorine reacts with organic matter in the water to form carcinogens such as trihalomethane and trihaloacetic acid. Chlorine has long been banned for the treatment of drinking water abroad. And boiling water can kill microorganisms in the water, which is a good strategy for ancient people to solve biological pollution. But today, boiling tap water cannot remove heavy metals, arsenides, cyanides, nitrites, organic pollutants and other harmful substances in the water. On the contrary, the content of ammonium nitrite (a strong carcinogen) in the water is significantly increased. Moreover, although the tap water meets the standards when it leaves the factory, it will cause secondary pollution when it passes through the old and damaged water supply pipe network.
According to a study by the World Health Organization, 80% of human diseases are related to drinking water. The more threatening to people is that harmful substances in the water accumulate in the body. If the liver, kidney, and spleen are assigned the task of eliminating the harm, then their burden will be too heavy.
