Title: Production Rule of By-products in Different Disinfection Processes of Tap Water
Abstract: Taking four WTPs using different disinfection processes and the same water source in a city as research object,the production rule of by-products in conventional liquid chlorine disinfection process and the combined process of chlorine dioxide and liquid chlorine was investigated.The results show that the content of by-products in the finished water from four WTPs is inferior to the national standard.The production of chlorination by-products can be effectively controlled by pre-chlorination with chlorine dioxide.The effect of the combined process on chlorination by-products is related to the mixture ratio of two disinfectors and the formation of precursors in source water.The effective action time of chlorine dioxide is shorter.WTPs with a large water supply area should apply the combined process to control chlorination by-products and ensure water quality in water distribution system.
