| 摘 要： | 目的了解昆山市集中式供水（区域供水）的水质现况。方法按照《生活饮用水标准检验方法》（GB/T5750-2006）对2009年昆山市集中式供水单位水源水、出厂水、末梢水进行水质检测、分析。结果 2009年共采集水样258份,合格253份,样品合格率99.2%。共检测5 990个项次,合格项次5 982个,项次合格率99.9%。其中水源水和出厂水样品合格率均为100%,末梢水样品合格率为97.5%。对末梢水不合格项目菌落总数和游离余氯按照监测点级别不同进行方差分析,市级及镇级游离余氯含量较高,菌落总数较低;村级余氯含量较低,菌落总数相对较高,甚至不达标。结论昆山市区域供水水质稳定、合格率高,特别是大大提高了农村饮用水水质状况。但也存在着整个供水管网游离余氯含量分布不均的现象,建议市自来水集团公司根据存在问题及时改进水处理工艺,进一步提高供水水质。
