摘要
[目的]了解临沂市农村饮用水卫生质量,掌握影响饮水安全的主要因素,为政府相关部门在提高农村饮水安全决策时提供科学依据。[方法]2008~2011年,在临沂市的12个区县设置农村生活饮用水供水监测点,分别于枯水期、丰水期,采集出厂水、末梢水进行检测。[结果]2008~2011年共检测各种水样2 084份,合格875份,合格率为41.99%。不同年份合格率分别为30.58%、31.43%、61.70%、48.38%(P<0.01);枯水期合格率为52.52%,丰水期合格率为31.27%(P<0.01);出厂水合格率为44.46%,末梢水合格率为40.02%(P<0.05)。合格率较低的项目有总大肠茵群(64.59%)、菌落总数(74.09%)、耐热大肠菌群(71.21%)、硝酸盐(77.64%)等。[结论]临沂市农村饮水合格率较低,影响合格率的主要因素是微生物和硝酸盐等指标。
[Objective]To investigate the hygienic quality of drinking water and water- borne diseases status in rural areas in Linyi city, and understand the main factors affecting safe drinking water, so as to provide scientific basis for decision- making by government departments. [Methods]During 2008-2011, monitoring points were randomly set up and the water samples were analyzed from centralized drinking Water supply spots in Linyi city. [Results]A total of 2084 water samples were collected and tested with 1075 qualified, the qualified rate was 41.99%. The qualified rate during 2008-2011 was 30.58 %,31.43%, 61.70% and 48.38%. respectively ( P 〈0.01). The qualified rate was 52.52 % in dry seasons, and 31.27% in wet seasons ( P 〈0.01). And finished water qualified was 44.46% with 40.02% of terminal water qualified ( P 〈0.05). Unqualified detected items were mainly total coliforms(64.59 %) ,bacterial colonies(74.09%),heat-resistant coliforms (71.21 % ), and nitrate(77.64%). [Conclusion] The qualified rate is lower in rural drinking water in Linyi city, mainly, caused by microbial indexes, and others such as high nitrates.
