福清市居民饮用水现状调查

Investigation on sanitary quality of drinking water in Fuqing city

目的掌握福清市居民饮用水现状,为政府决策提供科学依据。方法对福清市102家小型集中式供水和569户分散式饮水抽样调查分析。结果该市居民集中式供水占46.75%,分散式供水占53.25%;集中式供水主要以水库为水源占53.84%,分散式供水主要以浅井为主占85.00%;小型集中式供水水质未处理的占总水厂数90.00%;小型集中式供水水质合格率为47.79%,其中细菌总数、总大肠菌群、耐热大肠菌群的合格率分别为79.17%、56.86%、71.08%;分散式供水水质合格率24.08%,其中细菌总数、总大肠菌群、耐热大肠菌群的合格率分别为76.45%、43.59%、56.41%。结论福清市约50%居民为分散式供水,改水任务任重道远;饮用水水质合格率低,微生物超标为主因。

Objective In order to understand sanitary quality of drinking water in Fuqing, guarantee the safety of drinking water to the entire resident and provide scientific basis for supervision and inspection in FuQing. Methods 102 small - scale, centralized water supplies and 569 decentralized water supplies were surveyed. Results 46. 75% of population were taking drinking water from centralized water supply and the others using decentralized water supply（53.25% ）. The major water source of centralized water supply was reservoir water （53.84%）. And the major water source of decentralized water supply was Shallow water （85%）. The water of 90% mall -scale cen- tralized water supply was not treated. The eligible rate of small - scale centralized water supply was 47.79%. The eligible rate of the total colony count, total coliforms, Thermotolerant coliforms were 79.17% ,56.86% and 71. 08% respectively. Conclusion 50% of Fuqing population was taking drinking water from decentralized water sup- ply. It was better quickening the project of changing water supply. The drinking water quality in Fuqing was at low- er level. The main effect was microorganism which exceeded the standard.
