2009～2010年莒县农村部分饮用水水质卫生状况调查

Investigation on Sanitary Condition of Rural Drinking Water in Juxian,2009-2010

[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 sanitary condition of rural drinking water,provide information for making measures to improve management level of drinking water in rural area.[Methods]Water quality examination was conducted during low and high water period in rural areas from 2009 to 2010.[Results]Of the 200 water samples tested from 2009 to 2010,the qualified rate was 48.00%.The qualified rate was 47% and 49% in 2009 and 2010 respectively（P0.01）.The qualified rate was 55% and 20% from central water supply and decentralized water supply（P0.01）.The qualified rate was 60% and 39% during low and high water period（P0.05）.The qualified rate of turbidity,manganese,total hardness,total dissolved solids,ammonia nitrogen,nitrate nitrogen,oxygen consumption,aerobic bacterial count and coliform bacteria was 99.00%,96.00%,79.00%,99.50%,98.50%,97.50%,98.50%,49.00%,56.50% respectively.[Conclusion]The qualified rate of rural drinking water was lower,the water was seriously contaminated by microbial.
