2012年滨州市农村集中式供水水质卫生状况调查

Survey on Water Quality of Centralized Water-supply in Rural Areas,Binzhou City,2012

目的为保障滨州市农村人口的饮用水卫生安全,掌握农村饮用水供水现状。方法随机对滨州市农村集中式供水单位进行卫生学调查,并对采集的水样进行检测。结果共采集水样166份,超标严重的指标为菌落总数、二氧化氯、耗氧量COD;不同时期、不同水源类型的出厂水和末梢水菌落总数合格率差异均有统计学意义(P<0.01);末梢水菌落总数合格率显著低于出厂水(P<0.05)。结论滨州市农村集中式供水水处理工艺比较落后,末梢水合格率较低,微生物污染严重。
