目的 :了解福建省武夷山市农村分散式供水的水源水微生物污染状况,为改善农村生活饮用水的卫生质量提供依据。方法:2011-2014年在武夷山市辖区内10个乡、镇、街道及自然村收集327份水源水样品,依据GB/T5750-2006《生活饮用水标准检验方法》和HJ/T347-2007《水质粪大肠菌群的测定多管发酵法和滤膜法(试行)》检测;依据GB5749-2006《生活饮用水卫生标准》评价。结果 :福建省武夷山市农村分散式供水的水源水微生物指标总合格率84.4%,其中地表水合格率为86.0%,地下水合格率为78.3%;地表水合格率高于地下水。结论 :福建省武夷山市农村分散式供水的水源水微生物污染状况较好,但若将未经消毒的水源水直接饮用,仍有导致肠道传染病暴发流行的安全隐患。政府应加快农村供水设施建设,加强对饮用水源的卫生防护;加强饮用水安全知识宣传,提高群众饮水安全意识,以保障农村居民饮水安全卫生。
Objective: To understand the status of microbial contamination of source water in rural decentralized water supply in Wuyishan City, Fujian Province, and to provide basis for improving the hygienic quality of rural drinking water. METHODS: A total of 327 water source samples were collected from 10 villages, towns, streets and natural villages in the jurisdiction of Wuyishan City from 2011 to 2014. According to GB / T5750-2006 Standard Test Method for Domestic Drinking Water and HJ / T 347-2007 Water Quality Dung Coliform bacteria multi-tube fermentation and filter method (Trial) “test; based on GB5749-2006” drinking water health standards "evaluation. Results: The overall qualified rate of water source microorganism in rural distributed water supply was 84.4% in Wuyishan City, Fujian Province. The qualified rate of surface water was 86.0% and that of groundwater was 78.3%. The passing rate of surface water was higher than that of groundwater. CONCLUSION: Microbial contamination of water source water in rural decentralized water supply in Wuyishan City, Fujian Province is good. However, if unsanitary drinking water is directly consumed, there is still a potential safety hazard causing the outbreak of intestinal infectious diseases. The government should speed up the construction of rural water supply facilities to strengthen the health protection of drinking water sources; strengthen awareness of drinking water safety awareness, raise awareness of drinking water safety in order to protect rural residents drinking water safety and hygiene.
