2008年-2011年环江县农村生活饮用水水质监测结果分析

目的:了解环江县农村生活饮用水水质现状,为进一步改善水质质量,控制水源性疾病传播提供科学依据。方法:2008年-2011年连续对环江县460份农村生活饮用水水质进行监测。结果:2008年-2011年共检水样460份,合格112份,合格率24.3%,各年度的合格率差异有非常显著性(P<0.005);出厂水和末梢水的超标项目之间差异无显著性(P>0.25);丰水期和枯水期超标项目菌落总数、总大肠菌群、耐热大肠菌群之间差异有非常显著性(P<0.005)。结论:环江县农村生活饮用水被微生物污染严重,居民饮水质量不容乐观,应扩大集中式供水范围,加强对水质进行有效的消毒净化。

Surveillance result of the rural drinking water quality in Huanjiang county during 2008-2011

Objective:To explore the quality of drinking water in Huanjiang county and provide scientific evidence for the project of improving drinking water quality in rural areas.Methods:460 rural drinking water samples were monitored from 2008 to 2011.Results:112 of 460 samples were eligible in total,with the eligible rate of 24.3%.Eligible rate had significant difference among different years(P<0.005).Items exceeding the standard had no significant difference between factory water and tap water(P>0.25).The total plate count,total coliform and heat-resistant coliform had significant difference between dry season and wet season(P<0.005).Conclusion:Microbial contamination in rural drinking water was serious in Huanjiang county,so it was important to expand the centralized water supply range and strengthen effective water purification.
