浙江省2010年农村分散式供水水质现状分析

目的了解浙江省农村居民饮用分散式供水水质和卫生状况,预防饮水引起急慢性、化学性和介水传染病的发生。方法在浙江省11个市中选择有代表性县开展分散式供水基本情况调查和水质监测,对不同类型水源水和不同类型取水方式的水质,在丰、枯水期进行取样监测和评价。结果 26个县不同水源类型饮水点有25.19万处,饮水人数为201.24万人,占农村人口的16.70%;不同取水方式丰、枯水期的机械取水合格率分别为21.60%和31.03%;人力取水为14.81%和15.04%;手压泵取水13.79%和21.62%。结论浙江省农村分散式供水水质综合指标合格率较低,主要是水源水间接受不同环节污染机会较多所致。

The Quality of Scattered Water Supply in Rural Areas in Zhejiang Province

Objective To investigate the quality and health status of rural scattered water supply in Zhejiang Province,and provide scientific basis for the government.Methods Representative monitoring spots were selected from 26 counties to be investigated with a questionnaire on the basic situation.Samples of scattered water supply from different points were collected in wet and dry water seasons.The water quality was analyzed and assessed according to the related standards and regulation.Results There are 251.9 thousand scattered water supply spots in the 26 counties,covering 16.70% of the rural population.The pass rate of the mechanical sampling,manual sampling and handlance pump sampling in wet and dry water seasons is 21.60%,31.03% and 14.81% and 15.04%,13.79% and 21.62%,respectively.Conclusion The pass rates of composite index of scattered water supply from rural areas are low,which is related to the contamination during the water intaking.
