摘要
目的了解怀柔区农村生活饮用水卫生状况,保障居民饮水安全。方法选择有代表性的监测点进行调查和水质监测,采样、检验及评价方法按照GB/T 5750—2006、GB 5749—2006。结果2020年监测了饮水安全集中供水工程28处和5所小学校,全年共采集饮水安全供水工程水样112份,学校水样10份。农村饮水安全集中供水工程水样合格率为91.07%,学校水样合格率为100.00%。其中,丰水期水质合格率为89.29%,枯水期水质合格率为92.86%,枯水期水质合格率与丰水期相比,差异无统计学意义(χ^(2)=0.878,P>0.05);水质单项指标评价显示,氟化物、硝酸盐氮、总大肠菌群和耐热大肠菌群存在超标现象。结论怀柔区农村生活饮用水水质状况总体良好,但仍有一些指标不合格,应加强饮用水安全知识的宣传和卫生管理工作,进一步改善农村水质卫生状况。
Objective To understand the sanitary status of rural drinking water in Huairou District,ensure residents.drinking water safety.Methods The representative monitoring points were selected for investigation and water quality monitoring.The sampling,inspection and evaluation methods were in accordance with GB/T 5750—2006 and GB 5749—2006.Results Twenty eight drinking water safety centralized water supply projects and five primary schools were monitored in 2020.A total of 112water samples from safe drinking water supply project and 10 school water samples were collected throughout the year.The qualified rate of water samples for rural drinking water safety centralized water supply project was 91.07%,and the qualified rate of school water samples was 100.00%.Among them,the qualified rate of water quality in wet season was 89.29%,and that in dry season was 92.86%.The qualified rate of water quality in dry season was compared with that in wet season,and the difference was not statistically significant(χ^(2)=0.878,P>0.05).Water quality single index evaluation display,fluoride,nitrate nitrogen,total coliform and heat-resistant coliform exceed the standard.Conclusion The water quality of rural drinking water in Huairou District is generally good,but some indicators are still unqualified.The publicity of drinking water safety knowledge and sanitation management should be strengthened to further improve the water quality and sanitation in rural areas.
