平顶山市饮用水源地总大肠菌群(粪大肠菌群)污染现状及分析

Pollution situation and analysis of drinking water source coliform in Pingdingshan

地下水以总大肠菌群作为参评因子,地表水以粪大肠菌群作为参评因子,采用多管发酵法,对平顶山市饮用水源地水质进行监测与分析,了解污染现状,提出可行性意见及防治对策。结果表明:2010年、2011年度总大肠菌群指标均未超GB/T14848-93《地下水质量标准》Ⅲ类标准限值(MPN≤3.0个/L),粪大肠菌群指标的年均值均未超GB3838-2002《地表水质量标准》Ⅲ类标准限值(MPN<10 000个/L),其水质达到国家卫生安全标准。

In this study,total coliform bacteria was taken as participating factor;fecal coliform as a participating factor for surface water,and multiple tube fermentation method was adopted to monitor and analyze sources of drinking water so as to investigate the pollution status of groundwater and thus to propose feasibility advice and countermeasures.The results showed that the annual total coliform parameters were not super GB/T14848-93 groundwater quality standards for Class III standard limits（MPN≤ 3.0/L） in 2010 and 2011;the average annual concentration of fecal coliform indicators were not super-GB3838-2002 surface water quality standards for class III standard limits（MPN 10,000/L）,the water quality reached the national health and safety standards.
