摘　　要：以钱塘江水为原水 ,就净水工艺中加氯点不同所对应的消毒效果、消毒副产物的生成量及需氯量进行了模拟、检测和对比 ,取得了实验数据 .实验表明 ,加氯点后移对减少致癌副产物的生成、降低加氯量。Qian Tang River were taken as the sample of raw water, beaker pilot test, set chlorination point at the coagulation, sedimentation and filtration.Analyzed for water quality parameters.Comparied effect of chlorization, disinfectant by products and chlorine requirement. The result of the research shows that set chlorination point after the filtration was reasonable.
