2007-2009年双流县不同地形自备井水水质状况分析

Analysis on Self-sufficient Well Water Quality in Different Geographic Areas in Shuangliu County

目的分析双流县不同地形自备井水水质卫生状况,为居民安全饮水提供科学依据。方法按照《生活饮用水卫生标准》(GB5749-2006)采集2007-2009年双流县自备井水进行检测,对结果进行分析。结果 2007-2009年双流县自备井水总合格率分别为48.89%、46.81%和64.53%,平坝地区自备井水合格率、微生物合格率均高于丘陵地区(P<0.05)。结论双流县自备井水水质合格率呈逐年提高趋势,但总的合格率较低,不同地形水质质量有差异。

Objective To analyze the quality of water from self-sufficient wells in different geographic areas in Shuangliu,and provide scientific evidence to ensure drinking water security.Methods According to ＂Hygienic Criteria of Drinking Water Quality＂（GB5749-2006）,the water samples were taken from the self-sufficient wells of the residents in Shuangliu from 2007 to 2009 to conduct detection.Results The overall qualified rate of self-sufficient well water was 48.89% in 2007,46.81% in 2008 and 64.53% in 2009.The qualified rate and the qualified rate of microbiological indicators in self-sufficient well water in plain area were higher than those in hill area.（P0.05）.Conclusion The quality of self-sufficient well water in Shuangliu was improved by years,but the overall qualified rate was relatively low and the difference on water quality in different geographic areas was observed.
