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。
Objective To understand the decentralized drinking water quality and sanitation status of rural residents in Zhejiang Province and prevent the occurrence of acute, chronic, chemical and water-borne infectious diseases caused by drinking water. Methods Selected representative counties in 11 cities of Zhejiang Province were investigated for the basic situation of decentralized water supply and water quality monitoring. The water quality of different types of water sources and different types of water intake was sampled, monitored and evaluated in abundance and dry season. Results There were 251,900 drinking water points of different types of water sources in 26 counties, with the number of drinking water being 2,012,400, accounting for 16.70% of the rural population. The qualified rate of mechanical water abstraction was 21.60% and 31.03% 14.81% and 15.04% respectively; hand pump took water by 13.79% and 21.62%. Conclusion The decentralized water quality of rural decentralized water supply in Zhejiang Province is low, which is mainly due to the more opportunities for water sources to accept different aspects of pollution.
