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.

There are about 100 species plants in the wetland, and the majority is herbage and frutex. These plants included Polygonum hydropiper, Nelumbo nucifera, Annua Linn, Phragmites communis etc. At the same time, there are also 48 species animals, which belong to 30 families, and these animals included Ciconia ciconia, Cygrus cygrus, Platalea leucorodia, Meles meles etc.

湿地内有高等植物近100种，其中草本和灌木占大多数，典型的如水蓼、莲藕、早熟禾、芦苇等；在此栖息的动物有5纲共18目30科48种，具有代表性的如黑鹳，大天鹅、白琵鹭、狗獾等，是铜川市重要的水源补给地和湿地保护区，对于当地生态环境和经济社会可持续发展意义重大。
