目的:了解偃师市生活饮用水的基本状况,为实施农村供水、改水提供科学依据。便于今后科学制定饮水规划和采取防病措施。方法:收集2010年的检测资料,对偃师城区和16个乡镇的供水水质状况进行抽样检验,按照国家标准委和卫生部联合发布的GB5749-2006《生活饮用水卫生标准》中的要求进行评价。结果:我市城区主要饮用经过消毒处理的集中式供水,合格率较高,出厂水合格率100%,管网末梢水合格率90%;而农村生活饮用水以饮用未经任何处理的集中式供水为主,水质合格率偏低,全年总合格率仅46.7%,其中枯水期出厂水、末梢水的合格率均为63.2%,丰水期出厂水合格率为31.6%、末梢水的合格率为28.9%。结论:偃师城区生活饮用水水质良好,能够满足居民健康需求;偃师农村生活饮用水水质合格率偏低,微生物污染为本市农村生活饮用水污染的主要类型,本市农村存在着介水传染病流行的潜在危险;必须进行适当净化和消毒处理,加强对饮水水源的卫生防护,保护农村居民身体健康。
Objective: To understand the basic status of drinking water in Yanshi City, and to provide a scientific basis for the implementation of rural water supply and water diversion.
