摘　　要：[目的]保障济南铁路局辖区内生活饮用水水质的卫生安全,保护铁路职工及家属的身体健康,为生活饮用水的监督管理提供依据,防止水源性疾病发生。[方法]2005～2009年,对全局供水情况进行调查,采集水样进行水质检测。[结果]2005～2009年合计检测水样519份,各项指标全部合格的284份,合格率为54.72%。水样合格率,2005～2009年分别为45.45%、49.52%、60.68%、59.80%、57.29%(P<0.05);枯水期为56.92%,丰水期为52.51%(P>0.05)。519份水样中,感官卫生指标、一般化学指标、毒理学指标、微生物指标合格率分别为79.57%、61.07%、65.31%、57.61%,其中,感官卫生指标枯水期与丰水期合格率的差异有统计学意义(P<0.05)。检测合格率,菌落总数、总大肠菌群、色度、浑浊度的合格率分别为64.16%、88.63%、95.57%、97.69,总硬度、总固体、氯化物、硫酸盐、铁、锰、铜、锌分别为92.68%、91.71%、96.34%、95.38%、94.61%、96.72%、99.42%、96.72%,砷、铬、铅、汞、硝酸盐、三氯甲烷、四氯化碳分别为98.07%、99.23%、98.84%、98.65%、99.23%、94.61%、94.61%,其他指标全部合格。[结论]济南铁路局生活饮用水水质合格率较低,亟待提高微生物指标合格率。[Objective] To safeguard the hygiene and safety of drinking water quality in Ji＇nan Railway Bureau,protect the health of railroad employees and their families,provide the basis for drinking water＇s supervision and management and prevent water-borne diseases.[Methods]From 2005 to 2009,an investigation was made on the situation of water supply in the bureau,water samples were collected to detect water quality.[Results]From 2005 to 2009,a total of 519 water samples were detected,the indicators were all qualified in 284,with a passing rate 54.72%.Water passing rate,from 2005 to 2009 were 45.45%,49.52%,60.68%,59.80%,57.29%（P0.05）;dry season was 56.92%,wet period was 52.51%（P0.05.In 519 water samples,the sensory health indicators,general chemistry,toxicology,bacterial indicators of compliance rates were 79.57%,61.07%,65.31%,57.61%,with sense health indicators in the rate of compliance statistically significant in the dry and wet seasons（P0.05）.The qualified rate,colony count,total coliforms,color,turbidity in the pass rate of 64.16%,88.63%,95.57%,97.69,total hardness,total solids,chloride,sulfate,iron,manganese,copper and zinc were 92.68%,91.71%,96.34%,95.38%,94.61%,96.72%,99.42%,96.72%,arsenic,chromium,lead,mercury,nitrates,chloroform,carbon tetrachloride,respectively,98.07%,99.23%,98.84%,98.65%,99.23%,94.61%,94.61%,other indicators were all qualified.[Conclusion]The passing rate of drinking water quality in Ji＇nan Railway Bureau is lower,and passing rate of bacterial indicators need to be improved.
