In recent years, the most commonly used method for the tap water disinfection is chlorination. However, a lot of disinfection byproducts (DBPs) with the nature of carcinogenicity, teratogenicity, mutagenicity can be produced as by-products in the process of chlorination. Therefore, DBPs would do great harm to the city residents' health and normal life, and lead to water pollution. Thus, the research about the impacts of DBPs in water distribution system is of great value and emergency. In this paper, not only the standard working curve of several kinds of DBPs and the effects on the potential capacity for THMs in beaker experiment were investigated, but also the impacts of different pipe materials on the potential capacity for THMs by network experiments were determine.
