兰州铁路局铁路沿线供水点水质调查

SURVEY ON THE WATER QUALITY OF WATER SUPPLY SPOTS ALONG THE RAILWAY LINE OF LANZHOU RAILWAY ADMINISTRATION

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 spots along the railway line of Lanzhou railway administration,in order to ensure the safe supply along the railway.Methods Water sampling and testing on the spot of water supply point were used to monitor the water quality.Results During the period of year 2006-2011,576 copies water samples from water supply spots in different way were detected and the average pass rate of microbiology indicators was 68.75%.The average pass rate of centralized water supply spots was 96.26% and that of second water supply spots and distributed water supply spots were 78.01% and 55.42% respectively.Conclusion The comprehensive index of water quality of water supply spots along the railway line of Lanzhou railway administration is low and the quality of centralized supply water is good.So disinfection and cleaning of water supply along the railway should be strengthened.
