摘　　要：目的为近一步了解北京市怀柔区农村饮水水质卫生状况,保证农村饮水安全,提高农村居民的生活质量。方法分层随机抽取60个监测点,每个监测点在丰水期和枯水期各检测1次,每次采集出厂水和末梢水各1件,全年共检测水样240件。结果 2012年农村饮水安全工程集中供水240件,水样合格率为83.8%;枯、丰水期水质的差异有统计学意义(χ2=8.85,P<0.01);微生物学指标中总大肠菌群、耐热大肠菌群不同采样时间合格率差异有统计学意义(χ2=7.47,P<0.01;χ2=7.92,P<0.01);感官性状和一般化学指标以及毒理学指标全部合格。结论 2012年怀柔区农村饮水集中式供水水质总体状况较好,超标项目依旧主要集中在微生物学指标,今后应加大对微生物指标的监测力度以及消毒设备的投资力度,进一步改善农村水质卫生状况,保障农村居民身体健康。[ Objective ] To understand the sanitary conditions of rural drinking water in Huairou district, ensure the safety of drinking water in rural areas and improve the life quality of rural residents. [ Methods] 60 monitoring points were selected by stratified random sampling method,each monitoring point was tested once in the wet and dry seasons, finished water and peripheral water were collected and 240 water samples were detected one year. [ Results] The qualified rate of 240 water samples of centralized water supply of rural drinking water safety project in 2012 was 83.8%. The difference of it in dry and wet season was statistically significant （X2 = 8.85, P 〈0.01 ）. The difference of qualified rate of total coliforlns and therrnotolerant coliforms in different sampling times was statistically significant （ X2 = 7.47, P 〈 0.01 ; X2 = 7.92, P 〈 0.01 ）. Sensory traits, general chemical indicators and toxicological indicators were all qualified. [ Conclusion] The water quality of centralized water supply of rural drinking water safety project in Huairou district in 2012 is good, the items exceeded the standard is still mainly the microbiological indicators. We should enhance the monitoring of microbial indicators and the investment of disinfection equipment, further improve the sanitary status of rural water and protect the health of rural residents.
