[目的]了解淄博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的决策时提供科学依据。[方法]2008～2011年,在淄博市的9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2 432份,合格1 075份,总合格率为44.20%。不同年份合格率分别为30.86%、33.64%、48.17%、62.97%(P<0.01);枯水期合格率为55.76%,丰水期合格率为32.65%(P<0.01);出厂水合格率为52.14%,末梢水合格率为36.27%(P<0.01)。检测合格率较低的项目有总大肠菌群(65.21%)、菌落总数(75.64%)、耐热大肠菌群(82.65%)、硝酸盐(89.56%)。[结论]淄博市农村饮水合格率较低,影响合格率的主要因素是微生物指标,高氟、高砷及硝酸盐等问题也不容忽视。
[Objective] To understand the health quality of drinking water in rural Zibo, master the main factors affecting the safety of drinking water and provide scientific basis for the relevant government departments in improving the decision-making of rural drinking water safety. [Method] From 2008 to 2011, rural drinking water supply monitoring points in rural areas were set up in 9 districts and counties of Zibo City, respectively. During the dry season and wet season, the outlet water and the peripheral water were collected. [Result] A total of 2 432 samples of various kinds of water samples were obtained from 1 075 samples in 2008-2011, with a total pass rate of 44.20%. The pass rates in different years were 30.86%, 33.64%, 48.17% and 62.97%, respectively (P <0.01). The passing rate in dry season was 55.76% and that in wet season was 32.65% (P <0.01) %, The qualified rate of peripheral water was 36.27% (P <0.01). The total number of coliform (65.21%), colony (75.64%), heat-resistant coliform (82.65%) and nitrate (89.56%) were lower in the test. [Conclusion] The prevalence of drinking water in rural Zibo is low, the main factors affecting the qualified rate are the microbial indicators, high fluoride, high arsenic and nitrate and other issues can not be ignored.
