天津市农村饮用水水质现状调查

Investigation on the quality of drinking water in rural areas of Tianjin

目的 了解天津市农村饮用水水质现状,为改水工作提供科学依据。方法 对天津市的12个郊县共120个供水点(地面水41个,地下水79个)的水质进行了监测,根据《农村实施(生活饮用水卫生标准)准则》进行评价。结果 天津市农村饮用水水质,地下水丰、枯水期氟化物超标现象较严重,达不到三级水要求。地面水源丰、枯水期微生物指标超标现象较严重。结论 应加强地下水源除氟设施的管理,保证其正常运转,亦可依靠政府的力量,帮助农民定期进行降氟滤料的再生。对于地面水源应保证按时按量投加消毒药。
