摘　　要：目的了解怀柔区农村集中式供水水质卫生状况,为今后农村改水提供依据,使人民群众的日常饮水更加安全。方法在辖区内59个农村集中式供水水质监测点枯、丰水期采集出厂水、末梢水各1件,共计236件水样进行检测分析。结果 2011年农村集中式供水236件水样合格率为66.5%。枯水期与丰水期比较,差异有统计学意义(P<0.05)。水样中总大肠菌群不合格率为24.2%,耐热大肠菌群不合格率为21.2%,菌落总数不合格率为19.9%,肉眼可见物不合格率为2.1%,硝酸盐和氟化物不合格率均为1.7%,浑浊度不合格率为0.8%,氨氮和铁不合格率为0.4%。结论影响怀柔区农村集中式供水水质卫生状况的主要是微生物指标,今后应加强集中式供水管网配套设施的安装,针对不合格指标提出具体的改进措施,改善农村集中式供水水质卫生状况,以保障人们身体健康。[ Objective] To understand the sanitary quality of rural centralized water supply in Huairou District, provide the scientific basis for rural water improvement in the future, and ensure the drinking water safety. [ Methods ] 236 samples of finished water and tap water collected from 59 monitoring points of rural centralized water supply in Huairou District during dry season and wet season were tested and analyzed. [Results]The qualified rate of 236 water samples was 66.5%. The difference between dry season and wet season was significant （ P 〈 0.05 ）. The unqualified rate of total coliform group, thermotolerant coliform bacteria, total bacteria counts, visible substance, nitrate, fluoride, turbidity, ammonia nitrogen and iron was 24.2%, 21.2%, 19.9%, 2.1%, 1.7%, 1.7%, 0.8% 0.4% and 0.4%, respectively. [ Conclusion] The main influencing factors of sanitary quality of rural centralized water supply in Huairou District is microorganism. It is necessary to strengthen the installation of supporting facilities of centralized central water supply network, put forward the improvement measures according to unqualified items, and improve the sanitary quali- ty of rural centralized water supply, in order to protect the health of people.
