摘　　要：[目的]监测分析污染较重的地面水(五类或劣五类)经深度处理后,水中消毒副产物的含量及其动态,探[讨深度处理后自来水水质的安全性。[方法]依据水厂生产工艺中使用的臭氧氧化、二氧化氯与氯化混合消毒可能产生的消毒副产物指标,进行两年定时、定点监测。[结果]三卤甲烷、卤代乙酸及亚氯酸盐、氯酸盐、溴酸盐等14项消毒副产物含量明显低于现行国家生活饮用水卫生标准限值。[结论]平湖市对污染较重的自来水源水所采用的深度处理工艺是有效的,产生的消毒副产物含量较低,对人体是安全的。[Objective] Monitor and analyze the varieties and dynamics of the water disinfection by-products in the process of an advanced treatment to severely polluted source water（Grade V or V＋）,provide envidence to the safety regulation of drink water.[Methods] The possible by-products generated by water disinfection using ozonation or chlorine dioxide/chlorination method were monitored with a fixed locations and fixed time style in a period of two years.[Results] Total of 14 disinfection by-products,including trihalomethanes,halogenated acetic acids chlorites,chlorates,and bromates were significantly lower than current national health standards of drinking water.[Conclusion] The advanced treating process to severe polluted surface water is safe for daily usage in current study.
