【摘要】：目的了解江苏省城市生活饮用水水质情况,保障人民群众饮水安全。方法 2015年对全省155家城市水厂展开调查,枯、丰水期采集出厂水、末梢水、二次供水共2 398份,检测水质常规指标。结果 2015年江苏省城市生活饮用水水质合格率为89.07%,主要不合格指标为二氧化氯、游离余氯、菌落总数、耗氧量、总硬度、氟化物。地表水为水源的水质合格率为90.97%,地下水源的水质合格率明显低于地表水源,仅为62.96%;常规处理的水质合格率为90.88%,仅消毒、未处理分别为70.49%、42.11%;深度处理的水质合格率达到91.97%,未深度处理的水质合格率仅为86.08%。结论 2015年江苏省城市生活饮用水总体水质良好,主要不合格指标为消毒剂、微生物、一般化学指标;生活饮用水水质与饮用水水源、水处理技术密切相关。
[Abstract]:Objective to understand the situation of drinking water quality in Jiangsu Province and to ensure the safety of drinking water for the people. Methods in 2015, 155 urban water plants in the province were investigated. The water samples were collected from factory water, terminal water and secondary water supply in high water period, and the routine indexes of water quality were detected. Results the qualified rate of drinking water quality in Jiangsu Province was 89.07 in 2015. The main unqualified indexes were chlorine dioxide, free residual chlorine, total bacterial colony, oxygen consumption, total hardness and fluoride. The qualified rate of surface water as water source is 90.97. The qualified rate of groundwater source is obviously lower than that of surface water source, which is only 62.96. The qualified rate of conventional treatment is 90.88 and only disinfection. The qualified rate of water quality of advanced treatment was 91.97 and the qualified rate of untreated water quality was only 86.08. Conclusion the overall quality of urban drinking water in Jiangsu Province in 2015 is good, the main unqualified indexes are disinfectant, microorganism and general chemical index, the drinking water quality is closely related to drinking water source and water treatment technology.
