[目的]了解我区农村饮水改造工程卫生现状,为制订农村饮水安全工程规划提供科学依据。[方法]对2005～2007年完成的农水改造工程进行卫生学调查和水质检测。[结果]117份水样,合格率为61.54%,超标项目为硝酸盐氮、细菌总数、总大肠菌群。水质合格率,联村、管网延伸供水高于单村供水;II、III、IV型供水工程高于V型;地下水高于地表水;深层地下水高于浅层地下水;不同水处理方式,水质合格率差异有统计学意义。改水工程水源防护、卫生组织管理制度及消毒措施落实较差。[结论]莱城区农村饮水工程改造效果不容乐观,饮用水卫生安全在某些方面仍存在一定隐患,应引起各级政府和有关部门的高度重视。 [Objective] To understand the sanitary status of rural drinking water renovation project in our district and provide a scientific basis for the formulation of rural drinking water safety project planning. [Method] Hygienic investigation and water quality testing of agricultural and water remodeling projects completed from 2005 to 2007 were conducted. [Result] 117 samples were qualified with a pass rate of 61.54%. The over-standard items were nitrate nitrogen, total bacteria and total coliform bacteria. Water quality pass rate, the village, pipe network extension of water supply is higher than the single village water supply; Type II, III, IV water supply project is higher than V type; groundwater higher than surface water; deep groundwater higher than shallow groundwater; different water treatment methods, water quality The difference in pass rate was statistically significant. Water diversion project water protection, WHO management system and disinfection measures to implement poor. [Conclusion] The effect of reforming rural drinking water engineering in Laicheng district is not optimistic. The health and safety of drinking water still has some hidden dangers in some aspects, which should be paid great attention by all levels of government and relevant departments.
