[目的]了解莒县农村饮用水的卫生状况,为制定相关措施提高农村饮用水卫生管理水平提供依据。[方法]2009~2010年分别于枯水期和丰水期抽取莒县农村部分饮用水进行水质检测。[结果]2009~2010年合计检测农村饮用水水样200份,合格率为48.00%。水样合格率,2009年为47.00%,2010年为49.00%(P>0.01);集中式供水为55.00%,分散式供水为20.00%(P<0.01);枯水期、丰水期水样的合格率分别为60.00%、39.00%(P<0.05)。检测指标中,浑浊度、锰、总硬度、溶解性总固体、氨氮、硝酸盐氮、耗氧量、菌落总数、大肠菌群的合格率分别为99.00%、96.00%、79.00%、99.50%、98.50%、97.50%、98.50%、49.00%、56.50%。[结论]莒县农村饮用水水质合格率较低,主要是受到微生物污染。
[Objective] To understand the health status of drinking water in rural areas in Pixian County and provide the basis for formulating relevant measures to improve the sanitary management level of rural drinking water. [Method] The water quality of some rural villages in Pixian County was sampled during the dry season and wet season from 2009 to 2010. [Result] From 2009 to 2010, a total of 200 samples of drinking water in rural areas were tested with a pass rate of 48.00%. The passing rate of water samples was 47.00% in 2009 and 49.00% in 2010 (P> 0.01). The centralized water supply was 55.00% and the distributed water supply was 20.00% (P <0.01). The qualified water samples in dry season and wet season Rates were 60.00%, 39.00% (P <0.05). The pass rate of turbidity, total hardness, total dissolved solids, ammonia nitrogen, nitrate nitrogen, oxygen consumption, total number of colonies and coliform bacteria were 99.00%, 96.00%, 79.00% and 99.50% 98.50%, 97.50%, 98.50%, 49.00%, 56.50%. [Conclusion] The qualified rate of drinking water quality in Pixian rural area is low, mainly due to microbial contamination.
