What is a micro-polluted water source? Micro-polluted water source water refers to a water body that is contaminated with organic matter and some of its water quality indicators exceed the Class III water body standards of Surface Water Environmental Quality Standard (GB3838-2002). Micro-polluted water quality characteristics in four areas: (1) Affected by industrial wastewater and domestic sewage (2) a large increase in dissolved organic matter in water, (3) Harmful microorganisms harder to remove (4) The removal efficiency of endocrine disrupting substances (also called environmental hormones) is not high; Micro-polluted water how to deal with? 1 pretreatment technology Pretreatment technology can make the conventional treatment can better play a role in reducing the burden of conventional treatment and advanced processing can be divided into chemical oxidation, biological oxidation and adsorption. Chemical oxidation pretreatment commonly used three methods: Pre-chlorination oxidation Pre-chlorination measures are more commonly used, but excessive chlorine in water sources will produce chloroform, potentially carcinogenic to the human body and is not easily removed by the subsequent conventional treatment processes.It has been generally recognized that should be minimized in Chlorine in water purification process. Ozone oxidation Due to its strong oxidizing ability, ozone can gradually push the drinking water treatment by destroying the molecular structure of organic pollutants so as to change the nature of the pollutants. Potassium permanganate and permanganate complex oxidation Potassium permanganate and some inorganic salts made of organic compound complex of permanganate complex formed in the water treatment process with strong oxidizing ability of the intermediate components, can strengthen the removal of organic pollutants in water, strengthen the algae removal In addition to smell, in addition to taste, in addition to color, in addition to turbidity and so on. There are five ways to pre-treat biological oxidation: Â Biological Contact Oxidation The biofilm formed on the filler is flocculated and adsorbed and oxidized to degrade and remove the biologically utilizable pollutant matrix in the water. Tower biological filter The water purification function is achieved through the metabolic activity of the biofilm on the surface of the packing.
