摘要
[目的]全面了解崇左市生活饮用水卫生质量,保障居民生活饮用水安全,为崇左市生活饮用水卫生监督管理提供科学依据。[方法]按《生活饮用水卫生管理办法》《生活饮用水水质卫生规范》(2001)要求,对崇左市123家供水单位进行现场卫生监督检查,并对390份生活饮用水水质监测情况进行分析。[结果]共调查123家供水单位,93家集中式供水单位中水质完全处理率34.40%、不完全处理率25.81%、未处理率39.78%;市政供水水质完全处理率达100.00%。水样检测合格率69.23%;市政供水合格率(98.33%)比乡镇水厂合格率(67.56%)、自建水厂合格率(62.67%)、二次供水合格率(40.00%)高,差异有统计学意义(P<0.01)。不同检测项目中,合格率最低是细菌学指标70.26%。枯水期检测合格率(79.43%)比丰水期检测合格率(60.93%)高,二者差异有统计学意义(P<0.01)。[结论]崇左市市政供水生活饮用水安全状况良好,但乡镇水厂、自建水厂和二次供水单位仍存在卫生安全隐患,细菌学指标超标是影响生活饮用水卫生质量的主要原因。加强乡镇水厂、自建水厂和二次供水设施卫生监督及水质监测工作,进一步规范供水单位许可证发放管理,确保生活饮用水安全。
[Objective]In order to understand sanitary quality of drinking water in Chongzuo city, guarantee the safety of drinking water to all the resident and provide scientific basis for supervision and inspection in Chongzuo city. [Methods] According to " Hygienic Management for Drinking Water " and " Sanitary Standard of Drinking Water "(2001),on-the - spot supervision in 123 water supply units was conducted and 390 drinking water samples were analyzed. [Results]Of the 123 water supply units investigated, water completed treatment rate was 34.40% in 93 central water supply units, uncompleted rate was 25.81% , 39.78 % of them had no treatment; the rate of completed treatment in municipal administration water supply units was 100.00%. Of the 390 water samples,the qualified rate was 69. 230%. The qualified rate of water in municipal administration supply units (98.33 % ) was higher than that in villages and towns (67.56 % ). The qualified rate of water collected from self- constructed water supply was 62.67 % ,and from the second water supply was 40.00 % ,there was a significance difference ( P〈0.01). The qualified rate of bacteria was the lowest(70.26%) The qualified rate in dry season (79.43%) was higher than that in rich season( 60.93%), there was a difference ( P〈0.01). [Conclusion]The drinking water supplied under the municipal administration was safe, but there are still hidden troubles in villages and towns from self-constructed and second water supply units. The main affecting factor was the bacteria which was over the standard. Supervision must be strengthened. Test and delivery of hygienic license must be standardized to insure the quality of drinking water.
