目的了解兰州铁路局铁路沿线不同方式供水点水质状况,以保障路沿线供水安全。方法通过对供水点现场采集水样和检测方法,对兰州铁路局辖区内沿线供水点水质进行了监测。结果在2006-2011年期间,共检测不同方式供水点水样576份,微生物指标平均总合格率为68.75%。集中式供水点水中微生物指标平均合格率为96.26%;二次供水点水中微生物指标平均合格率为78.01%;分散式供水点水中微生物指标平均合格率为55.42%。结论兰州铁路局铁路沿线不同供水点水质综合指标偏低,以集中式供水水质较好,应加强铁路沿线供水消毒与净化。
Objective To understand the water quality of water supply points in different ways along the railway line of Lanzhou Railway Bureau so as to ensure the water supply safety along the road. Methods The water quality of water supply points along the Lanzhou Railway Administration was monitored by collecting water samples and testing methods from the water supply site. Results During 2006-2011, a total of 576 water samples were collected from different ways. The average total qualified rate of microbial indicators was 68.75%. The average passing rate of microorganisms in centralized water supply was 96.26%. The average passing rate of microorganisms in secondary water supply was 78.01%. The average passing rate of microorganisms in water was 55.42%. Conclusion The comprehensive indexes of water quality at different water supply points along the railway line of Lanzhou Railway Bureau are low, and the water quality of centralized water supply is better. The water supply along the railway should be strengthened to disinfect and purify.
