目的分析邵武市农村饮水安全工程饮用水卫生状况,为制定农村改水政策提供依据。方法调查全市农村饮水工程概况,按GB/T 5750-2006《生活饮用水标准检验方法》和GB/T 5750-2006《生活饮用水卫生标准》开展检测和评价。结果全市共有569个饮水工程,供水能力可覆盖92%的农村人口。工程规模以<50t(73.8%)及供水覆盖人口<500人(88.2%)为主,水源以地面水为主(80.8%),水处理方式以沉淀过滤为主(93.0%)。水质总合格率44.1%,枯水和丰水期、地面和地下水、出厂和末梢水合格率比较均无统计学意义;33个检测项目总合格率95.6%;毒理学指标合格率99.5%、一般化学指标99.3%;感官指标91.6%,微生物指标70.1%,消毒剂指标65.0%。结论邵武市饮水安全工程大部分供水能力小,工艺简单,水质合格率较低,应加强监管。
Objective To analyze the health status of drinking water in rural drinking water safety project in Shaowu City and provide the basis for formulating rural water reform policy. Methods Survey the city’s drinking water project in rural areas, according to GB / T 5750-2006 “drinking water standard test method” and GB / T 5750-2006 “drinking water health standards” to carry out testing and evaluation. Results The city has a total of 569 drinking water projects, with water supply capacity covering 92% of the rural population. The scale of the project is mainly composed of <50t (73.8%) and water supply population <500 (88.2%). Groundwater is the main source of water (80.8%). Sediment filtration is the main method of water treatment (93.0%). The total qualified rate of water quality was 44.1%. There was no significant difference in passing rate between dry and wet season, ground and groundwater, shipping and peripheral water passing rate. The total pass rate of 33 test items was 95.6%. The pass rate of toxicological indicators was 99.5% Chemical indicators 99.3%; sensory indicators 91.6%, microbial indicators 70.1%, disinfectant indicators 65.0%. Conclusion Most of Shaowu drinking water safety project has a small capacity of water supply, simple process and low qualified rate of water quality, which should be strengthened.
