摘　　要：目的掌握福州地区市政供水水质状况,为加强市政供水安全管理和改善饮用水水质提供科学依据。方法选取福州地区所有的市政水厂作为监测点进行监测,水样采集、保存和检测按照《生活饮用水标准检验方法》(GB/T 5750—2006)进行,检测结果评价按照《生活饮用水卫生标准》(GB 5749—2006)进行。结果三年采集、检测市政供水样品968份,合格率为95.1%,其中出厂水合格率为97.5%,末梢水合格率为94.8%;2019年市政末梢水合格率高于2017年(χ^(2)=4.911,P=0.027)和2018年(χ^(2)=4.100,P=0.043),组间比较差异有统计学意义;不同类型检测指标中的微生物指标超标率高于感官性状(χ^(2)=9.123,P<0.01)、一般化学指标(χ^(2)=20.075,P<0.01)和毒理指标(χ^(2)=70.096,P<0.01),组间比较差异有统计学意义。结论福州地区市政供水水质状况总体较好,饮用水监测工作对水质改善起到了推动作用,但郊县市政供水水质状况还有提升空间,同时仍需要关注微生物指标引起的水质问题。Objective To master the water quality of municipal water supply in Fuzhou Area and provide scientific basis for strengthening the safety management and improving the quality of municipal water supply.Methods All municipal water plants in Fuzhou Area were selected as monitoring points for monitoring.Water samples were collected,preserved and tested according to the Standard Test Method for Drinking Water(GB/T 5750-2006).The test results were evaluated according to the Hygienic Standard for Drinking Water(GB 5749-2006).Results 968 municipal water supply specimen in three years were collected,and the qualified rate was 95.1%,pass percentage of supply tap water was 94.8%.The standard rate of municipal supply tap water in 2019 was higher than that in 2017(χ^(2)=4.911,P=0.027)and 2018(χ^(2)=4.100,P=0.043).The exceeding standard rate of microbial indexes was higher than that of sensory properties(χ^(2)=9.125,P<0.01),general chemical indexes(χ^(2)=27.075,P<0.01)and toxicological indexes(χ^(2)=70.096,P<0.01).Conclusion The municipal water quality in Fuzhou Area is generally good,and drinking water monitoring has played a role in promoting the improvement of water quality.However,there is still room for improvement in the quality of municipal water supply in suburban areas.At the same time,it is necessary to pay attention to the water quality problems caused by microbial indexes.
