目的了解株洲市区生活饮用水微生物指标状况,为饮用水生活管理提供依据。方法回顾分析2009-011年株洲市生活饮用水水质监测样品微生物检测指标。结果出厂水各检测项目合格率全部为100.0%,井水的菌落总数、大肠菌群、耐热大肠菌群和大肠埃希菌群四个项目的合格率分别为72.2%、83.3%、88.9%、88.9%;管网末梢水菌落总数和大肠菌群合格率均为100.0%,二次供水和直饮净水两个指标的合格率分别为97.1%、99.7%和89.4%、99.2%。结论株洲市市政管网供水及二次供水微生物指标合格率比井水和直饮净水高。
Objective To understand the status of microbial indicators of drinking water in Zhuzhou City and provide the basis for drinking water life management. Methods Retrospective analysis of 2009 - 011 Zhuzhou City drinking water quality monitoring samples microbial indicators. Results The passing rate of all test items in the factory water was 100.0%. The pass rates of the colony, coliforms, heat-resistant coliform and Escherichia coli in well water were 72.2%, 83.3% and 88.9% respectively, , 88.9% respectively. The total numbers of water colonies and coliform bacteria were 100.0% and 97.1%, 99.7% and 89.4%, 99.2% respectively for secondary water supply and direct drinking water. Conclusion Zhuzhou Municipal Pipe Network Water Supply and Secondary Water Supply Microbiological Qualification Rate is higher than that of well water and drinking water.
