摘　　要：对福州市城区的14个管网点进行为期1a的游离氯、浑浊度、pH等22项水质指标跟踪检测。结果表明,该市管网水质基本符合标准,综合合格率达到99.73%,其中pH、浑浊度、菌落总数、铁的单项指标合格率分别为96.75%、99.35%、99.35%、99.35%,其余水质指标单项指标合格率均为100%。供水交汇处的水质最不稳定,虽然季节变化和区域分布对管网水质有一定的影响,但水质指标基本都在国家标准范围内。菌落总数、游离氯、铁等水质指标存在一定的相关性。A one-year tracking test of 22 water quality indices such as residual chlorine,turbidity,pH,etc.was carried out on 14 sampling sites in urban area of Fuzhou City.The results showed that the water quality of the water supply network in the city basically met the standard,and the comprehensive qualified rate reached 99.73%,of which the single qualified rates of pH,turbidity,total number of bacterial colonies,and Fe were 96.75%,99.35%,99.35%,and 99.35%,respectively;And the single qualified rates of the rest of the water quality indices were all 100%.The water quality at the water supply intersection was the most unstable,although seasonal changes and regional distribution had some influence on the water quality of the water supply network,but the water quality indicators were basically within the range of national standards.There was a certain correlation between water quality indices such as total number of bacterial colonies,free residuals chlorine and Fe.
