[目的]调查莆田市集中式供水水质状况。[方法]莆田市对市政供水5a监测结果进行分析。[结果]摸清了集中式供水的水质状况。进厂水水质良好,无受到工业污染,出厂水合格率96.35％,末消水合析率94.13％,丰水期合格率84.71％,枯水期合格率95.24％,丰、枯两期水质质量差异存在非常显著性,(x~2=24.52,P<0.01),枯水期水质优于丰水期。单项指标分析,细菌总数和总大肠菌群合格率较高,而浑浊度和游离余氯合格率较低。[结论]供水单位应加强水质卫生管理,认真贯彻执行《生活饮用水卫生管理办法》,提高供水质量,保障人体健康。
[Objective] To investigate the centralized water quality in Putian City. [Method] Putian City, municipal water supply 5a monitoring results were analyzed. [Result] Finding the water quality of centralized water supply. Into the factory water quality is good, without industrial pollution, the passing rate of the factory water 96.35%, the end of the water analysis rate of 94.13%, the wet season pass rate of 84.71%, dry season 95.24% pass rate, abundance, dry water quality differences exist two very Significant, (x ~ 2 = 24.52, P <0.01), dry season water better than wet season. Single index analysis, the total number of bacteria and the total coliform bacteria pass rate is higher, while the turbidity and free residual chlorine lower pass rate. [Conclusion] The water supply unit should strengthen the sanitary management of water quality, conscientiously implement the “Measures for the Administration of Sanitation of Drinking Water”, improve the quality of water supply and protect human health.
