摘要
目的了解农村生活饮用水的卫生状况,制定农村饮水安全工程规划。方法2008年4—5月,对潍坊市农村饮用水安全工程进行基本情况调查和水质抽样检测。结果该市农村生活饮用水以地下水为主,深层地下水占80.95%,完全处理的工程水质占4.23%,有消毒设施的供水工程仅占2.64%;抽检的378份水样,总合格率为47.09%,出厂水和末梢水合格率分别为51.32%和50.26%;超标项目主要是硝酸盐(以氮计)、菌落总数、总大肠菌群,超标率分别为11.38%、31.75%、14.55%。结论潍坊市农村饮用水微生物和硝酸盐超标较严重,水质检测合格率较低,农民饮水存在安全隐患。
[ Objective ] To understand the hygienic status of rural drinking water, and develop project planning for the safety of drinking water. [ Methods] In April and May of 2008, the safety engineering project in rural areas of Weifang was investigated for its general situation, and water quality was also tested by sampling. [ Results ] Drinking water in rural areas mainly came from ground water, among which deep ground water occupied 80.95%. water treated completely occupied 4.23%. The water supply project with sterilized equipment only accounted for 2.64% ; of 378 water samples, the total qualified rate was 47.09%. The qualified rate of finished water and terminal water was 51.32% and 50.26% respectively; The unqualified items included nitrates （ in terms of nitrogen with 11.38% beyond the standard）, the total number of colonies（31.75% beyond the standard）, total coliforms （ 14.55% beyond the standard）. [ Conclusion]The contents of micro-organisms and nitrates exceed the norms severely. The qualified rate of wa- ter quality was relatively low. Potential safety hazard exists in rural drinking water.
