组合氯化消毒工艺的卤代消毒副产物生成特性

Halogen disinfection by-products of four chlorined disinfection processes with long contact time in distribution system was compared in the work.These four disinfection processes are free chlorine,monochloramines,free chlorine disinfection in clearwelles while chloramines in distribution system,sequential chlorination disinfection with short-term free chlorine plus chloramines.According to the research,free chlorine generates most trihalomethanes(THMs) and haloacetic acids(HAAs) both in clearwells and distr...
