浙江省农村水厂出厂水水质调查监测情况分析

Survey on finished water quality of rural waterworks in Zhejiang province

目的:为了进一步了解和掌握浙江省农村水厂出厂水饮水水质和卫生状况,预防农村饮用水质超标引起中毒和介水肠道传染病发生。方法:在全省选择有代表性的监测点开展农村饮水基本情况调查,并对不同水处理方式的水厂和不同水源类型的出厂水,在丰、枯水期进行采样监测,按照国家《生活饮用水卫生标准》(GB 5749-2006)进行评价。结果:402个乡镇有78.74%左右的农村人口饮用了农村集中式工程的给水;不同水处理方式和不同水源水的出厂水质综合指标丰、枯水期的合格率分别为88.2%和88.3%。结论:农村水厂出厂水水质综合指标合格率较低,主要是水厂处理工艺不够完善,消毒不够规范等所致。

Objective：To understand the finished water quality and prevent intoxication and prevalence of water-born infection diseases for the unqualified rural drinking water.Methods： Representative monitoring areas were selected to investigate the basic information of rural drinking water.Water samples were taken in wet season and dry season respectively according to waterworks of different water treatment and finished water of different water source types.Water quality was evaluated by Sanitary Standards for Drinking Water（GB 5749-2006）.Results： 78.74% of rural population got drinking water from centralized water supply in 402 villages and towns.According to the comprehensive indexes,the pass rates of the rural water quality in wet season and dry season were 88.2% and 88.3% respectively.Conclusion： The most reason for low pass rates of finished water quality of rural waterworks may be unperfect treatments and unstandard disinfection.
