More and more attention is focusing on the safty of drinking water suply. In this paper, firstly, chloramine formation and the characteristics and kinetics of monochloramine autodecomposition were studied. Secondly, considering the high concentration of ammonia and the complication of organic matters in Shanghai Huangpu River, formation characteristics and rules of disinfection byproducts were reviewed during the breakpoint chlorination process, and on the basis of grading and clssification of organisms, the control effects of chloramination on DBPs formation were studied. Finally, the formation rules of 2-monochlorophenol, 2,4-dichlorophenol and 2,4,6-trichlorophenol from phenol chlorination were investigated, and related influencing factors and kinetics were analysed.
