目的分析福建省境内铁路分散式供水监测情况,为铁路分散式供水的监管提供依据。方法对2006—2011年铁路分散式供水点卫生档案及水质监测资料进行分析和评价。结果共采集水样311件,合格率17.4%,2006—2011年水样合格率均处于低水平状态(<30%)。除菌落总数(54.7%)、总大肠菌群(36.4%)、耐热大肠菌群(51.1%)、浑浊度(82.6%)和肉眼可见物(84.2)外,其余指标的合格率均在90%以上。水源以溪水的微生物指标合格率最低(13.3%)。结论福建省境内铁路分散式供水水质合格率较低,主要受微生物指标尤其是总大肠菌群的影响,分散式供水水质亟待改善。
Objective To analyze the situation of railway distributed water supply monitoring in Fujian Province and provide the basis for the supervision of railway distributed water supply. Methods The data of sanitary archives and water quality monitoring data of railway distributed water supply points from 2006 to 2011 were analyzed and evaluated. Results A total of 311 water samples were collected, with a pass rate of 17.4%. The passing rates of water samples from 2006 to 2011 were all at a low level (<30%). Except for the total number of colonies (54.7%), total coliforms (36.4%), heat-resistant coliforms (51.1%), turbidity (82.6%) and macroscopic (84.2) %the above. Microorganisms of water source to stream the lowest pass rate (13.3%). Conclusion The decentralized water quality of railways in Fujian Province is low, which is mainly affected by microbial indicators, especially the total coliform bacteria. The quality of distributed water supply needs to be improved urgently.
