江西铁路沿线饮用水源分散,点多线长,辖区内南昌、九江、吉安、赣州、鹰潭、上饶、景德镇、萍乡、宜春和新余等10个地区共100多个水源,分布在铁路沿线车站、工务段工区、车务段和房建生活段给水所。为了解江西铁路沿线生活饮用水中消毒副产物的污染现状,笔者于2012年6月—2013年5月对南昌铁路局江西境内火车站、给水所、列车、水厂等供水点水样中亚氯酸盐和氯酸盐含量进行调查。按照GB/T 5750—2006《生活饮用水标准检验方法》对水样中亚氯酸盐和氯酸盐含量进行测定,方法的检出限分别为0.002和0.005 mg/L,平均回收率分别为102.0%和100.0%,RSD分别为1.251%和1.017%。按照GB5749—2006《生活饮用水卫生标准》进行评价,亚氯酸盐和氯酸
There are over 100 water sources in 10 areas including Nanchang, Jiujiang, Ji’an, Ganzhou, Yingtan, Shangrao, Jingdezhen, Pingxiang, Yichun and Xinyu within the jurisdiction of the railway, which are distributed along the railway stations, Public Works Works Area, traffic and housing construction section of water supply. In order to understand the pollution status of disinfection by-products in domestic drinking water along the railway in Jiangxi Province, the author studied the water samples of water supply stations like Jiangxi Railway Station, water supply station, trains and water plants in Nanchang Railway Administration from June 2012 to May 2013 Chlorate and chlorate levels were investigated. According to GB / T 5750-2006 Standard Test Method for Drinking Water, the detection limits of chlorite and chlorate in water samples were 0.002 and 0.005 mg / L, respectively. The average recoveries were 102.0% and 100.0% with RSDs of 1.251% and 1.017%, respectively. In accordance with GB5749-2006 “drinking water health standards” for evaluation, chlorite and chlorate
