为了解北京铁路局生活饮用水水质状况，对辖区６个铁路卫生防疫站１９９３～１９９７年上报的生活饮用水监测数据进行了统计分析。结果表明给水所、二次供水、分散式给水消毒率分别为４５．８１％、７６．４７％、４３．１８％；全局饮水超标指标主要是细菌学指标，消毒饮水的细菌学指标合格率高于未消毒饮水；５年来，随着消毒率的不断提高，饮水水质有所改善。表明生活饮用水消毒对提高水质起到明显的作用。
In order to understand the water quality of drinking water in Beijing Railway Bureau, statistical analysis was conducted on drinking water monitoring data reported by 6 railway health and epidemic prevention stations from 1993 to 1997. The results showed that the disinfection rates of water supply, secondary water supply and distributed water supply were 45.81%, 76.47% and 43.18% respectively. The indicators of excessive drinking water were mainly bacteriological indicators, and the qualified rate of bacteriological indicators of drinking water was high In non-sterile drinking water; 5 years, with the continuous improvement of disinfection rate, drinking water quality has improved. Show disinfection of drinking water to improve water quality played a significant role.
