目的了解云南省通海县生活饮用水微生物污染状况,为饮用水卫生监督管理提供依据,防止水源性疾病发生。方法回顾分析通海县2011—2013年生活饮用水水质微生物检测结果,按照卫生部《生活饮用水卫生规范》(2006)进行细菌学监测和评价。结果通海县2011—2013年生活饮用水水质微生物检测合格率分别为51.37%,63.82%,69.74%,县城水厂供水总合格率为89.19%,二次供水合格率为72.54%,农村集中式供水合格率为52.72%,分散式供水合格率为27.12%。结论通海县生活饮用水微生物检测合格率偏低,农村集中式供水和分散式供水污染严重,应加强对各类水源的防护,确保全县人民的饮水安全。
Objective To understand the status of microbial contamination of domestic drinking water in Tonghai County, Yunnan Province, and to provide a basis for health supervision and management of drinking water to prevent water-borne diseases. Methods A retrospective analysis of Tonghai drinking water quality 2011-2013 microbial test results, according to the Ministry of Health, “Drinking Water Health Code” (2006) for bacteriological monitoring and evaluation. Results The qualified rates of drinking water quality tests in Tonghai from 2011 to 2013 were 51.37%, 63.82% and 69.74% respectively. The total qualified rate of water supply in county waterworks was 89.19% and the qualified rate of secondary water supply was 72.54%. The rural centralized water supply The pass rate is 52.72%, decentralized water supply pass rate is 27.12%. Conclusion Tonghai drinking water microbial detection pass rate is low, the rural centralized water supply and decentralized water supply pollution is serious, should strengthen the protection of various types of water sources to ensure that the people of the county drinking water safety.
