摘要
目的了解福建省永定县农村饮水安全工程水质卫生状况,探讨农村饮水安全工程建设及卫生管理策略。方法对农村饮水安全供水工程水质连续监测2年,水质检验按GB/T 5750-2006规定进行,结果按GB 5749-2006进行评价。结果饮水安全工程水源地面水占66.7%,地下水占33.3%(其中山泉水19.0%);完全处理占11.9%,沉淀过滤占59.5%,未处理28.6%。2年水样总合格率26.8%,地下水合格率(41.1%)高于地面水(19.7%)(χ2=17.48,P<0.01);主要超标项目是微生物学指标,水样合格率较低是饮水安全工程水质无消毒处理导致。结论永定农村饮水安全工程水质微生物超标严重,存在传播介水传染病的隐患,建议加强水源保护和饮水消毒工作,加强供水工程监管及日常卫生管理工作,加强水质卫生监测。
[Objective]To understand the sanitary situation of water quality of rural drinking water safety projects in Yongding County of Fujian Province,explore the construction and health management strategies of rural drinking water safety project.[Methods]The water quality of rural drinking water safety projects was monitored continuously for 2 years.The detection was conducted according to GB/T 5750-2006,and the results were evaluated according to GB 5749-2006.[Results]For the source of water in drinking water safety projects,the surface water accounted for 66.7%,and the ground water accounted for 33.3%（19.0% were spring water）.11.9% were treated completely,59.5% were treated with sedimentation and filtration,and 28.6% have not been treated.The total qualified rate of water samples in 2 years was 26.8%,while the qualified rate of ground water（41.1%） was higher than that of surface water（χ2=17.48,P0.01）.The main over-standard items were microbiological indicators.The low qualified rate of water samples was caused by lack of disinfection treatment.[Conclusion]The microbiological indicators of rural drinking water safety projects in Yongding County exceed the standards greatly,and there are the latent dangers of water-borne infection disease.It is recommended to strengthen the water source protection and drinking water disinfection,improve the supervision of water supply projects and daily health management,and enhance the health monitoring of water quality.
