Water as the origin of life, people in daily life and manufacturing activities are indispensable water, the quality of daily drinking water quality and our health is closely related. Along with the times is the economic and social development. Scientific research development and the improvement of people’s living standards, we continue to improve the water quality requirements for daily life, drinking water quality standards also continue to progress and improve.Amway傳銷 of the water quality standards for daily drinking water and our way of life. Cultural creativity. Economic development norms. Technology and innovation development trend level. Water source and its water body status and other factors, not only in the middle of the world, but also in the middle of the same China’s different regions, the provisions of drinking water quality have a difference.
Shenzhen water quality monitoring indicators
1. Saturation: the saturation of drinking water such as more than 15 degrees when most people can be found, beyond thirty degrees to make people feel tired. Specifications require the saturation of drinking water can not exceed 15 degrees.
2. Turbidity: for water quality sampling electronic optical properties of an expression used to describe the level of water clarity and turbidity, is one of the most important indicators to consider the excellent level of water, but also to assess the effectiveness of water purification equipment purification solution and evaluation of the state of sewage treatment technology is an important link. The reduction of turbidity represents the organic matter in the water body. germs. Viral infections and other germ components are reduced, which can not only enhance the actual effect of disinfection and sterilization, but also help to reduce the formation of halide organic matter.
3. odor and taste: water odor is usually generated by the appearance of organic matter, which may be the result of increased biological activity show or industrial production pollution. Publicity power supply all normal odor changes may be the source water body changes or wastewater treatment is not sufficient to cause the signal.
4. The human eye is thus visible: the key refers to the occurrence of water. Can be observed by the human eye particles or other floating compounds.
5. permanganate index: permanganate index is the amount of chlorine remaining in the water after the water is chlorinated and disinfected and touched for a certain amount of time. The water has a continuous sterilization effect can prevent the water supply pipe of its own pollution, to ensure that the supply of water.
6. permanganate index: is the organic chemical oxide oxidation of organic chemical pollutants in amway濾水器 air coefficient. The greater the organic chemical oxygen consumption, the more organic chemical pollutants in the water. The key organic chemical pollutants in water from domestic sewage treatment or industrial effluent discharge. Animal and plant decay and melting caused by the injection into the water body.
7. The number of germs: the water with germs, from the gas. Soil layer. Sewage. Waste materials and animal and plant carcasses, the c in the water is colorful, and it includes germs. In China, the specification for drinking water is that the number of germs in 1ml of water should not exceed one hundred.
8. Total coliform: is a fecal pollution indicator bacteria, from which the actual situation can be tested to show whether there is fecal pollution in the water and its pollution level. In the whole process of purification of crude salt, based on sterilization and disinfection Artistry評價 coliform index, such as can do the requirements of drinking water specifications, that other pathogenic bacteria are also basically solved. Norms to be no more than 3 / L in the test.
9. heat-resistant E. coli: it is more appropriate than E. coli to reflect the level of food category contaminated by animal and human feces, but also the water body fecal contamination indicator bacteria.
