目的了解盐城市亭湖区省级监测点水质卫生状况。方法分别于枯水期和丰水期,采集省级监测点出厂水和末梢水进行水样检测。结果 2011—2013年检测水样440份,样品合格率为72.27%,以深井水为水源的水样合格率(73.13%)高于以湖泊水为水源的水样(41.67%),差异有统计学意义(P<0.05)。累计检测项目8 800项次,项次合格率为93.95%,不合格项目包括游离余氯、氯化物、氟化物、菌落总数、总大肠菌群、耐热大肠菌群、浑浊度、溶解性总固体、铁、肉眼可见物、硝酸盐等11项。结论亭湖区农村生活饮用水水质合格率偏低,需加强监督监测和综合防治,确保居民饮水安全。
Objective To understand the sanitary status of water quality in provincial monitoring stations in Pavilion Lake, Yancheng City. Methods During the dry season and wet season respectively, water samples were collected from the factory water and the peripheral water at the provincial monitoring points. Results 440 samples were tested in 2011-2013, with a pass rate of 72.27%. The pass rate of water samples with deep well water as the source (73.13%) was higher than that of water samples with lake water (41.67%), with statistical difference Significance (P <0.05). A total of 8800 items were tested and the pass rate was 93.95%. The unqualified items included free residual chlorine, chloride, fluoride, total number of colonies, total coliforms, heat-resistant coliforms, turbidity, total dissolved Solid, iron, visible to the naked eye, nitrate and other 11 items. Conclusion The passing rate of rural drinking water in rural areas in Tingting District is low. Supervision, monitoring and comprehensive prevention and control should be strengthened so as to ensure residents’ drinking water safety.
