[目的]了解济南铁路辖区饮用水水质状况,以便对存在的问题进行改进。[方法]2010年2~12月根据GB5750-2006、GB 5749-2006分别对济南铁路辖区二次供水、小型集中供水、分散式供水和集中供水4种水源水质进行检验和卫生学评价,检验数据用SPSS统计软件包处理。[结果]检测水样87份,合格30份,合格率为34.48%。水质合格率由高到低依次为:二次供水和小型集中供水均为(50.00%)、集中式供水(33.33%)、分散式供水(14.71%),4种水源全部指标合格率间差异有统计学意义(P<0.05)。各项检测指标中,消毒剂合格率最低是游离余氯(44.26%)。[结论]济南铁路辖区饮用水水质合格率偏低,应加强对生活饮用水管理和技术的指导和监督。
[Objective] To understand the status of drinking water quality in Jinan railway area in order to improve the existing problems. [Method] According to GB5750-2006 and GB5749-2006 from February to December 2010, the water quality of four water sources in secondary water supply, small centralized water supply, distributed water supply and centralized water supply in Jinan railway area were tested and evaluated hygienically. The test data SPSS statistical package processing. [Result] 87 water samples were tested, 30 samples were qualified, the pass rate was 34.48%. The qualified rate of water quality from high to low is as follows: secondary water supply and small centralized water supply are both (50.00%), centralized water supply (33.33%), distributed water supply (14.71%), Statistical significance (P <0.05). Among the testing indexes, the lowest pass rate of disinfectant is free residual chlorine (44.26%). [Conclusion] The passing rate of drinking water quality in Jinan railway area is low, and the guidance and supervision of life drinking water management and technology should be strengthened.
