目的了解北京市延庆县农村饮用水卫生状况,分析影响延庆县农村饮用水卫生质量的因素,为全县农村实施改水工作提供科学依据。方法依据《2009年北京农村饮水水质卫生监测技术方案》随机选取65个集中式供水点,分别在枯水期、丰水期采集出厂水和末梢水进行水质监测。结果枯、丰水期水质合格率均为43.8%,出厂水合格率为51.5%,末梢水合格率为36.2%,差异有统计学意义(χ2=5.02,P<0.05)。结论延庆县农村饮用水卫生状况不容乐观,需进一步完善农村改水工作,加强农村饮用水消毒工作,有关部门应加强宣传和监测力度。 Objective To understand the health status of rural drinking water in Yanqing County, Beijing, and to analyze the factors affecting the hygiene quality of rural drinking water in Yanqing County, and to provide a scientific basis for the implementation of water diversion in rural areas of Yanqing County. Methods According to “2009 Beijing rural drinking water sanitary monitoring technical program” randomly selected 65 centralized water supply points, respectively, during the dry season, harvesting factory water and peripheral water collected water quality monitoring. Results The qualified rate of water quality in both dry and wet periods was 43.8%. The qualified rate of water produced in the factory was 51.5% and the qualified rate of peripheral water was 36.2%. The difference was statistically significant (χ2 = 5.02, P <0.05). Conclusions The hygiene status of rural drinking water in Yanqing County is not optimistic. It is necessary to further improve the water diversion work in rural areas and to strengthen the disinfection of drinking water in rural areas. Relevant departments should step up publicity and monitoring efforts.
