2008年-2010年南平市城乡饮用水卫生状况分析

The analysis of drinking-water sanitation in cities and towns of Nanping in the year 2008-2010

目的:了解南平市城乡生活饮用水卫生状况,为提高饮用水卫生管理质量提供科学依据。方法:对2008年-2010年南平市城乡集中式供水和分散式供水的水质检测资料进行统计、分析和评价。结果:三年共检测样品689份,合格率为68.2%。其中集中式供水水样586份,合格率为80.9%;分散式供水水样103份,合格率为49.2%,集中式供水水样合格率与分散式供水水样合格率比较有显著性差异。水源水、山泉水和井水中合格率最低的是细菌总数和总大肠菌群。出厂水和末梢水各项目的合格率均在93.9%以上。结论:集中式供水水样合格率明显高于分散式供水水样的合格率;水源水、山泉水、井水是影响我市城乡饮用水合格率的主要因素;提高水质净化处理技术,加强水源地管理是保证饮水安全的关键。

Objective：To improve the health management quality of drinking water by learning the sanitary conditions of water used in daily life in the city of Nanping.Methods： Water quality detection data from centralized and dispersal water provision in 2008-2010 were counted,analyzed and evaluated.Results： The number of samples in 3 years are totally 689 with qualification rate of 68.2%.There are 586 samples of centralized water supply with qualification rate of 80.9% and 103 pieces of samples from dispersal water supply with qualification rate of 49.2%.The difference of qualification rate between the two types of provision is obvious.The lowest qualification rates of all in the source water,spring water and well water are the total number of bacterial and colon bacillus.For water after process and tap water the qualification rate in all terms are over 93.9%.Conclusion： The qualification rate of samples from centralized water supply is obviously higher than that of the dispersal water supply.The quality of the source water,spring water and well water is the main element that influences the qualification rate of civil water in cities and towns of Nanping.Enhancing the management of water head site and improving the water treatment technology are both key points to guarantee the safety of drinking water.
