目的了解潍坊市农村饮水安全工程水质卫生状况。方法对全市已建成运行的农村饮水安全工程水质状况进行采样检测,集中式供水工程检测出厂水和管网末梢水,末梢水按照供水2万人设1个监测点,不足2万人口至少设1个监测点。联村和单村供水工程只检测末梢水。检测项目为常规指标。结果共采集水样992份,水质检测合格率为81.05%,集中式供水出厂水和末梢水水质检测合格率分别为89.80%和72.40%,二者比较差异有统计学意义(χ2=6.5 7,P<0.05);联村和单村供水水质检测合格率分别为88.3 7%和82.77%。结论集中式供水的管网末梢水和单村供水工程所供水质存在卫生安全隐患较多。
Objective To understand the water quality and hygiene of rural drinking water safety project in Weifang City. Methods The water quality of rural drinking water safety projects that have been completed and operated in the city was sampled and tested. The centralized water supply project detected the water of factory and the end of the pipe network. The peripheral water provided 1 monitoring point according to the water supply of 20,000 people and the population of less than 20,000 was set at least 1 A monitoring point. Union Village and single village water supply project only detects peripheral water. Test items for the conventional indicators. Results A total of 992 water samples were collected and the pass rate of water quality test was 81.05%. The passing rate of water quality of the extrinsic water supply and the peripheral water of centralized water supply was 89.80% and 72.40%, respectively, with significant difference (χ2 = 6.57, P <0.05). The passing rate of water quality in Lian Village and Shan Village was 88.3 7% and 82.77% respectively. Conclusion There is more health and safety hazard in the water quality of centralized water supply pipe network and single village water supply project.
