摘要
目的:为了解和掌握浙江省农村水厂管网末梢水饮水水质和卫生状况,确保农村居民饮水卫生安全,预防农村水厂管网末梢水超标的水质引起中毒和介水肠道传染病的发生。方法:在全省选择有代表性的监测点开展农村水厂管网末梢水饮水基本情况调查,并对不同水处理方式的水厂和不同水源类型的管网末梢水,在丰、枯水期进行采样监测,按照国家《生活饮用水卫生标准》(GB5749-2006)进行评价。结果:全省选择的有代表性的监测点,被选的403个乡镇有81.44%左右的农村人口饮用了农村集中式水厂的供水;水厂管网末梢水以不同水处理方式和采用不同水源水的水质综合指标丰、枯水期的合格率分别为93.58%和94.03%。结论:农村水厂管网末梢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 investigate the peripheral water pipe network quality and health status of rural water plants of zhejiang,to provide a assurance for the dirkning water qulailty in rural areas,and prevent from the poisoning and water-borne diseases that are resulted from unquality of the peripheral water pipe network.Methods： Select the representative monitoring points to have a questionnaire investigation about the peripheral water pipe network of villages,and the drinking water samples from different approachs of rural water plants and diferent water types of the peripheral water pipe network were collected in wet and dry season,then the water quality was analyzed and assessed according to the related standards and regulation.Results： In 403 towns of monitoring points,about 81.44% of rural population drink the water from rural water plants,the pass rate of composite indexs in wet and dry season,which are count by different approachs of rural water plants and diferent water types of the peripheral water pipe network,are 93.58% and 94.03% respectively.Conclusion： The pass rate of composite indexs in the peripheral water pipe network of rural water plants is relatively low,which is related to imperfect of process and irregular disinfection.
