摘要
[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 investigate the hygienic quality of drinking water and waterborne diseases status in rural areas in Zibo 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 Zibo city. [Results]A total of 2 432 water samples were collected and tested with 1 075 qualified, the qualified rate was 44.20%. The qualified rate during 2008-2011 was 30.86% ,33.64% ,48.17%, and 62.97% respectively（ P 〈0.01）. The qualified rate was 55.76% in dry seasons, and 32.65% in wet seasons（ P 〈0.01）. And finished water qualified was 52.14% with 36.27% of terminal water qualified （ P〈0.01）. Unqualified detected items were mainly total coliforms（65.21 % ）, bacterial colonies（75.64 % ）, heat - resist- ant coliforms （82.65 % ）, and nitrate（89.56 % ）. [Conclusion]The qualified rate is lower in rural drinking water in Zibo city,mainly caused by microbial indexes,and other issues such as high fluoride,high arsenic and nitrates cannot be ignored.
