目的了解潍坊市农村饮水的卫生状况。方法依据《生活饮用水卫生标准》随机抽取农村饮水,采用调查表法对每个监测点的水源类型、供水方式、水处理方式、消毒情况进行卫生学调查和水质检测。结果该市农村饮水以地下水为主,深井水占81.82%(153/187)。经完全消毒处理的水源仅占3.21%(6/187),无消毒设施的占98.40%(184/187);抽检的374份水样,检测总合格率为44.92%;出厂水和末梢水合格率分别为48.13%和45.99%;主要超标项目是菌落总数、总大肠菌群和硝酸盐氮,超标率分别为31.18%、14.44%和11.50%。结论该市农村饮水水质检测合格率较低,农民饮水存在安全隐患。
Objective To understand the health status of rural drinking water in Weifang City. Methods Based on “drinking water health standards”, rural drinking water was randomly selected, and water quality, water quality, and type of water supply, water supply methods, water treatment methods and disinfection conditions were monitored by questionnaires. Results The rural drinking water in the city was mainly groundwater, with deep well water accounting for 81.82% (153/187). The disinfected water source accounted for only 3.21% (6/187), no disinfection facilities accounted for 98.40% (184/187); sampling of 374 water samples, the test pass rate was 44.92%; ex-factory water and the end of the water grid The rates were 48.13% and 45.99% respectively. The main items that exceeded the standard were total number of colony, total coliforms and nitrate nitrogen, exceeding the limit of 31.18%, 14.44% and 11.50%, respectively. Conclusion The passing rate of rural drinking water quality test in this city is low, and farmers’ drinking water has potential safety problems.
