目的：了解威海市市区饮用水三卤甲烷的含量水平。方法选取威海市区的10个管网末梢水采样点作为监测对象，检测饮用水三卤甲烷( THMs)、pH值、游离余氯。结果所有水样均检出了三卤甲烷，合格率为100%。夏季水样中三氯甲烷的含量明显高于冬季；所有水样的pH值，冬季明显高于夏季；游离余氯合格率为78.00%。结论威海市市政管网末梢水三卤甲烷各项指标均符合国家标准，供水单位应在保证三卤甲烷指标合格的情况下，加强消毒剂的投入，保障居民的饮用水安全。

[Abstrct] Objevtive To explore the level of the THMs in drinling water in Weihai. Methods The samples were selected from 10 taps in Weihai. The indices including Trihalomethanes (THMs),PH and Free Chlorine Residual were detected. Results The pass rate of THMs decteced from all samples were 100%, The total amount of THMs in summer is significantly higher than that in win-ter;The seasonal variations of PH were high in winter and low in summer; The percent of pass of Free Chlorine Residual were 78.00%. Conclusion The amount of THMs in Weihai’s water net keeps within the limits of Health Standards of Drinking- water. To ensure the safety of people’s Drinking-water,The water sector should strengthen the disinfectants’s input in guaranteeing qual-ification of THMs.
