摘　　要：目的针对某铁路局辖区供水水质现状提出保障水质安全的建议。方法于2012年4月—2013年4月对该局主要铁路干线沿途部分供水站点进行调查采样,共收集水样214份,水样检测项目共23项,检测及评价方法按照《生活饮用水标准检验方法》(GB/T 5750-2006)及《生活饮用水卫生标准》(GB 5749-2006)执行。结果该局主要铁路干线的214份水样中,合格水样89份,合格率41.59%。其中,管井直供水样187份,合格率40.11%,路外购买水样27份,合格率51.85%;水样主要不合格指标为浑浊度、氯化物、硫酸盐、溶解性总固体、总硬度、氨氮。结论该路局辖区供水水质卫生存在隐患,针对其供水行业特点,从技术和管理两方面提出保障供水卫生安全的对策及建议。Objectives To understand the quality of drinking water in railway sites under the jurisdiction of a Railway Bureau,and make recommendations for protecting the quality and safety of drinking water. Methods A total of 214 water samples were collected from April 2012 to April 2013,the detection and evaluation of samples was based on the Standard Examination Method for Drinking Water（ GB / T 5750- 2006） and rhe Standards for Drinking Water Quality（ GB 5749- 2006）. Results Among 214 water samples collected in this study,only 89 water samples were qualified,and the qualified rate was 41. 59%. The qualified rate of 187 water samples collected from tube wells was 40. 11%,and the qualified rate of 27 water samples purchased from markets was 51. 85%.The main unqualified indexes were turbidity,chloride,sulfate,total dissolved solids,total hardness and ammonia.Conclusions There were some hidden dangers on the quality of drinking water in some railway sites under the jurisdiction of the Railway Bureau. Based on the characteristics of water-supply industry for railway sites,the causes of pollution were analyzed; control measures and suggestions from both technical and management aspects were put forward.
