2011年全国生活饮用水卫生安全情况调查和分析

目的:调查我国集中式供水单位、二次供水设施和学校自备供水设施的卫生管理状况和供水水质质量。方法:对市政水厂、自建水厂和二次供水设施的卫生管理情况进行调查。对出厂水、末梢水、二次供水以及学校自备水进行水质监测。结果:自建集中式供水单位、二次供水单位、自备供水学校的饮用水仍需进一步加强,集中式供水出厂水、末梢水、二次供水水质合格率较高,均在85%以上,学校自备供水水质稍差,合格率为70%。结论:应高度重视我国饮用水卫生安全问题,市政供水单位的水质实验室自检能力、自建水厂和学校自备供水设施的卫生管理工作尚需加强,水质监测方面应重点关注学校自备供水的水质安全。

Investigation on drinking water safety in China in 2011

Objective:To investigate the health management condition and water quality of centralized water supply units,secondary water supply facilities and School-owned water supply facilities in China.Methods:Data identification,on-site investigation,sampling test were conducted on water samples from municipal water supply facilities,self-built water factories,secondary water supply facilities and school-owned water supply facilities in 2011.Results:The health management of self-built centralized water supply units,secondary water supply units and School-owned water supply facilities remain to be standardized;Water test results indicated that treated water,tap water and water from secondary water supply were commendable with eligible rates more than 85%,the pass rate of water samples from school-owned water supply was 70%.Conclusion:Great importance should be attached to China′s drinking water safety.Self-test capability of water quality laboratory in municipal water supply units,health management of self-built centralized water supply factroies and school-owned water supply facilities still need to strengthen.Water quality monitoring should focus on water safety of school-owned water supply facilities.
