南京铁路管区站车生活饮用水微生物污染监测与分析

为了解上海铁路局南京疾病预防控制所管区内各火车站和列车饮用水的细菌污染状况,提高饮用水的卫生质量,总结分析了2004~2006年对所供饮用水的定期监测情况。结果显示:3年共检测水样391件,合格356件,合格率91.0%。其中车站末梢水284件,合格270件,合格率95.1%。列车二次供水107件,合格86件,合格率80.4%。表明车站末梢水的合格率与列车二次供水的合格率相比较,两者有显著性差异。因此,必须进一步落实列车自备水箱的清洗消毒制度,进行定期清洗消毒,对相关人员进行卫生知识的培训,加强日常卫生监督监测工作,则是控制列车饮用水二次污染,提高列车二次供水合格率的关键。

The Microorganism Polluting Monitoring and Analysis of the Drinking Water in Nanjing Railway Area

Object:In order to know the status of bacteriological contamination about the drinking water of the railway stations and trains,and improve the hygienic quality of the drinking water.Methods:The samples of water were taken and examined.Results: The results showed that 356 of 391 samples were eligibility with an eligible rate of 91.0% in 3 years,270 of 284 samples of stations were eligibility with an eligible rate of 95.1%,86 of 107 samples of trains were eligibility with an eligible rate of 80.4%.Conclusions: The eligible rate of the drinking water in railway stations is significantly higher than in trains.Therefore,the drinking water in trains of the second bacteriological contamination should be controlled.Perfect disinfection system should be established and the main work is washing and disinfection of water box.Training of the related persons hygienic knowledge should be enhanced. Supervision and monitoring of the drinking water should be strengthened in these trains.It is the key that eligible rate of drinking water is highter.
