摘    要:目的了解南京市村镇小水厂水质卫生现状及影响因素,为改善农村饮用水质量、加强村镇水厂的卫生管理提供依据。方法设计和制作了《南京市乡镇村级小水厂卫生状况调查表》、《南京市乡镇村级小水厂饮用水水质卫生监测结果登记表》,对全市6家涉农区县134家村(镇)水厂开展相关调查。结果 134家村镇水厂枯水期出厂水合格率为79.1%,末梢水合格率71.8%;丰水期出厂水合格率68.2%,末梢水合格率58.8%。枯水期与丰水期比较,差异有统计学意义(P0.01)。不合格项目主要为微生物指标和感官指标。结论该市村镇小水厂的饮用水质量枯水期水质较丰水期好,影响该市村镇小水厂饮用水质量的因素主要为微生物指标和感官指标,原因是水厂管网老化、净化消毒设施使用率低,监管部门应增加此类水厂的水质监测频率,加强卫生监督工作。
