目的了解福州城区市政自来水水质状况,及时发现和处理饮用水存在的健康危害因素,为制定城市饮用水安全保障措施提供依据。方法 2010-2012年每季度在鼓楼区、台江区、晋安区、仓山区各随机抽取10个市政自来水管网末梢水点进行监测,按GB/T 5750-2006《生活饮用水标准检验方法》检测。结果 2010-2012年共采集水样480份,合格率为92.9%。3年监测合格率菌落总数97.1%、总大肠菌群98.8%;理化指标中除浑浊度98.3%、铁96.7%,其余项目均为100.0%。4个季度合格率分别为90.8%、92.6%、91.7%和96.7%;各城区合格率分别为:鼓楼区95.0%、台江区95.8%、晋安区94.2%、仓山区86.7%。结论福州市市政自来水末梢水的水质状况总体正常,但仓山区水质合格率偏低,应加强水质净化处理和自来水管网更换与维修。
Objective To understand the quality of municipal tap water in Fuzhou city and discover and deal with the health hazards of drinking water in time and provide the basis for the development of safe drinking water in urban areas. Methods From 2010 to 2012, ten municipal tap water pipelines were randomly selected from each district in Gulou District, Taijiang District, Jinan District and Cangshan District for monitoring.

The qualified rate of 3-year monitoring was 97.1% of the total number of colonies and 98.8% of the total coliform bacteria. The physical and chemical indexes except turbidity of 98.3% and 96.7% of iron were 100.0% for the remaining projects. The passing rates in four quarters were 90.8%, 92.6%, 91.7% and 96.7% respectively. The pass rates in urban areas were 95.0% in Gulou District, 95.8% in Taijiang District, 94.2% in Jinan District and 86.7% in Cangshan District.
