摘要: 目的 分析2008—2022年淮安市农村生活饮用水水质变化趋势,为淮安地区进一步提升农村生活饮用水安全水平提供参考依据。方法 收集2008—2022年淮安市农村生活饮用水监测数据,分析水质合格率和变化趋势。结果 2008—2022年淮安市共监测农村生活饮用水23 501份,总体合格率为88.9%;2008—2022年农村生活饮用水合格率范围为84.3%~100.0%,总体呈上升趋势(P<0.05);主要不合格项目为总大肠菌群、菌落总数、耐热大肠菌群、浑浊度、肉眼可见物、锰、铁等,项目合格率均呈上升趋势(均P<0.05),项目含量总体呈下降趋势(P<0.05);但耗氧量值自2017年起开始持续上升(P<0.05),氯化物、硫酸盐、溶解性总固体、总硬度等指标值2022年开始有上升趋势。结论 2008—2022年淮安市农村生活饮用水总体合格率呈上升趋势,水质得到显著改善,与有效实施区域集中供水策略相关。但部分指标含量总体下降后,近年又呈上升趋势,值得关注。

Abstract: Objective To analyze the trend of changes in rural drinking water quality in Huai'an City from 2008 to 2022,and provide reference for further improving the safety level of rural drinking water in Huai'an area. Methods Collect monitoring data of rural drinking water in Huai'an City from 2008 to 2022,analyze the qualified rate and the change trend of water quality. Results From 2008 to 2022,a total of 23 501 rural drinking water samples were monitored in Huai'an City,with an overall qualified rate of 88.9%. The qualified rate of rural drinking water ranged from 84.3% to 100.0% from 2008 to 2022,which showed an overall upward trend(P<0.05). The main unqualified items included the total coliform bacteria,total colony,heat-resistant coliforms, turbidity,visible substances,manganese,iron,etc.,and the qualified rate of the items showed an upward trend(P<0.05),the overall content of the items showed a downward trend(P<0.05). However,the oxygen consumption value had been continuously increasing since 2017(P<0.05),while indicators such as chloride,sulfate,soluble total solid,and total hardness had shown an upward trend since 2022. Conclusion From 2008 to 2022,the overall qualification rate of rural drinking water in Huai'an City showed an upward trend,and the water quality was significantly improved,which is related to the effective implementation of regional centralized water supply strategies. However,after the overall decrease in some indicators,they have shown an upward trend in recent years,which is worth paying attention to.
