Test results of microorganism in drinking water in Tonghai County of Yunnan Province from 2011-2013

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 microbial contamination status of drinking water in Tonghai County of Yunnan Province, to provide the basis for drinking water hygiene supervision and management, and prevent water diseases. [ Methods ] Retrospective a- nalysis was performed on microbiological test results of drinking water in Tonghai County from 2011-2013. Bacteriological monito- ring and evaluation were based on the ＂ Drinking Water Health Standards ＂ （2006 } developed by Ministry of Health. [ Results ] The qualified rate of microbiological test results of drinking water in Tonghai County was 51.37%, 63.82%, 69.74% ,the total qualified rate of water from the county water supply was 89.19% ,the qualified rate of secondary supply water was 72.54% ,that of centralized water supply in rural areas and decentralized water supply was 52.72% and 27.12%, respectively. [ Conclusion] The qualified rate of microbiological test results of drinking water is relatively low in Tonghai County. The contamination of centralized water supply in rural areas and decentralized water supply is serious. It is necessary to strengthen the protection of various water sources, and ensure drinkin~ water safety of the people in this county.
