2009年南昌市农村生活饮用水水质卫生监测现况分析

目的分析南昌市农村饮用水水质卫生状况,为行政部门制订干预措施提供科学依据。方法分别于2009年枯水期(3~4月)及丰水期(7~8月)采集水样,按照标准方法进行检测、评价、分析。结果合格率为100%的指标分别为:色度、总硬度、硫酸盐、氯化物、臭和味、溶解性总固体、耗氧量、氨氮、砷、氟化物;超标率较高的指标分别为:总大肠菌群(50.76%)、耐热大肠菌群(33.33%)及菌落总数(21.97%)、浑浊度(11.36%)、PH值(24.24%)。分散式供水水样浑浊度、PH值、总大肠菌群、耐热大肠菌群超标率大于集中式供水水样(P<0.05);集中式供水水样菌落总数超标率大于分散式供水(P=0.034)。结论我市农村饮用水卫生仍然存在较多问题,尤其以微生物污染为重,而水源管理不当及消毒工作未有效开展是导致农村饮用水微生物超标的主要原因,因此,应加强饮用水水源管理及消毒工作。
