针对浙江省内具有代表性的水源水，测定采用液氯消毒工艺的出厂水中消毒副产物的种类及浓度，了解进水水质、温度、pH值等因素对生成消毒副产物的影响，并进行健康风险评价。结果表明：①五类或劣五类源水经深度处理的出厂水中的三卤甲烷和卤乙酸的含量高于一类或二类源水经常规处理的出厂水中的三卤甲烷和卤乙酸的含量，但均低于国家标准限值；②水中溴离子浓度增加会引起氯代消毒副产物浓度下降，溴代消毒副产物浓度升高；③水中氨氮浓度升高，三卤甲烷浓度降低；④温度、pH值变化对消毒副产物的浓度影响不明显；⑤代表性水源水出厂水中的卤乙酸相对致癌风险较大，对人体健康有一定影响。

Targeted at the typical source water in Zhejiang Province ,this paper determines all kinds and concentrations of disinfection by‐products of effluent of using liquid chlorine disinfection process ,and understand water quality ,temperature and pH on the effect of disinfection by‐products ,and discusses the health risk assessment of disinfection by‐products .The results show that :① triha‐lomethanes and haloacetic acids contents of deep treatment of effluent for five or bad five classes of source water were higher than that of conventional treatment of effluent for one or two classes of source water ,but they are lower than the national standard limit;② the increase in bromide ion concentration can cause chlorinated disinfection by‐products concentration decreasing ,and bromined disinfection by‐products concentration increasing ;③ the increase in concentration of ammonia nitrogen will cause the decrease in tri‐halomethanes concentration;④ the effects of temperature and pH on disinfection by‐products are not obvious;⑤ the relative cancer risk of haloacetic acids of effluent for the typical source water is high ,which has a certain influence on human health .
