摘要
[目的]做好生活饮用水的卫生与安全管理工作,防止水质污染,减少和杜绝水源性疾病的发生。[方法]2010～2012年,对济南铁路局辖区内183家生活饮用水供水单位的饮用水安全与卫生管理工作采取整改措施,并对措施实施的效果进行评价。[结果]调查的183家生活饮用水供水单位中,卫生许可证持有、预防性卫生监督审查、从业人员健康证持有、消毒产品有效批件持有、涉水产品批件持有、水污染事故应急预案建立、消毒设备配置的合格率,安全与卫生管理整改后均高于整改前(P<0.01或<0.05);采用漂白粉或二氧化氯消毒者所占比例,整改前为46.45%,整改后为59.56%(P<0.01)。整改前后分别检测水样93份和452份,所有指标均合格者所占比例,整改前为70.97%,整改后为80.09%(P<0.05),其中,色度、浑浊度、总固体、铁、锰、氯化物、硫酸盐、游离余氯、总大肠菌群的合格率,整改措施实施后均高于实施前(P<0.01或<0.05),其他指标合格率整改前后的差异均无统计学意义(P>0.05)。[结论]济南铁路局实施的生活饮用水安全与卫生管理措施取得一定成效,尚需进一步加强管理、落实消毒措施。
[Objective]To strengthen the sanitary and safe management on the drinking water, so as to prevent the con- tamination of drinking water;decrease and eliminate the incidence of water-borne disease. [Methods]Rectifying and impro- ving measures were taken on the safety and sanitary management in 183 water-supplying units of Jinan Railway Bureau and evaluation was made on the rectification effect during 2010-2012. [Resuits]A total of 183 water -supplying units were surveyed,the possession of hygiene licence, preventive sanitary supervision, the practitioner health cards psossession, the effective parcel possession of disinfection products, the parcel possession of products involveddrinking water, the formula- tionof water-polluted accidents emergency project,the pass rate of disinfection implement equipped, the safety and sanitary management were higher than before rectification （ P 〈0.01 or 〈0.05）. The rate of using chloride or chlorine dioxide for disinfection before and after rectification was respectively 46.45 % and 59.56 %（ P 〈0.01）. 93 water samples tested be- fore rectification and 452 samples after rectification, the pass rate was respectively 70. 97 % and 80.0 9 %（P 〈 0.05 ）. Among these indicators, the pass rate of color shade opacity, total solid, Ferrum, Managese, Chloride, sulphate flee chlorine residual, total coliform were higher than before rectification. The other indicators＂ pass rate had no statistic difference（ P 〈0.05）. [Conclusion]The measures on the safety and sanitary management of drinking water in Jinan Railway Bureau have acquired effect, and further management should be taken and the disinfection measures should be taken.
