2009年-2011年昭平县农村饮用水卫生状况分析

Analysis of rural drinking water sanitary status in Zhaoping from 2009 to 2011

目的:了解昭平县农村饮用水卫生状况,为改善农村居民饮用水水质提供科学依据。方法:按照GB/T5750-2006《生活饮用水标准检验方法》进行检测,按照GB/T5749-2006《生活饮用水卫生标准》进行评价。结果:三年间共检测水样300份,总合格率为36.33%,年度间合格率差异有显著性(P<0.05);集中式供水水样合格率与分散式供水水样合格率差异有高度显著性(P<0.001)。结论:昭平县农村生活饮用水水质卫生合格率逐年提高,受微生物污染严重,集中式供水水样合格率高于分散式供水水样合格率,应扩大集中式供水范围,加强对水质进行有效的净化消毒,确保农村居民饮用水安全。

Objective： To understand the quality of rural drinking water in Zhaoping, to provide scientific basis for improving the quality of rural drinking water. Methods： The water quality test was conducted according to ＂Stand- ard examination methods for driking water＂ （ GB/T5750 - 2006）, and the result was evaluated according to ＂Stand- dard for driking water quality＂ （ GB/T5749 - 2006）. Results ： Three hundred water samples were tested during the 3 years,the overall pass rate was 36.33% , and there was significant difference among the three years. The signifi- cant difference was also found between the pass rates of the centralized water supply and the decentralized water sup- ply （P 〈 0. 001 ）. Conclusion： The pass rate of the drinking water has increased annually in Zhaoping county, but polluted by microorganisms seriously. The pass rate of the centralized water supply is higher than the decentralized＇s. It is suggested to expand the scope of the centralized tion of the water quality, thus ensuring the safety of water supply, strengthen the effective purification and disintec- the rural drinking water.
