2006—2010年兰州铁路局铁路沿线自备集中式供水水质变化分析

Analysis on the Water Quality of Centralized Water Supplies along the Railway Lines f Lanzhou Railway Administration in 2006—2010

摘要

摘要:
目的通过分析兰州铁路局铁路沿线自备集中式供水水质的状况，为制定安全自备集中式供水策略提供参考依据。
方法利用2006—2010年间兰州铁路局辖区的6个车务段自备集中式供水卫生监督监测资料，对水质进行统计学分析。
结果自备集中式供水水质菌落总数、总大肠菌群和耐热大肠菌群等微生物指标总体合格率均在95%以上; 水质毒理学、感官性状和一般化学等指标基本没有变化，大多数指标合格率基本都保持在90%左右。
结论兰州铁路局铁路沿线自备集中式供水水质质量良好。

Abstract:
Objectives To provide theoretical basis for establishing strategies of keeping the water from centralized water suppliers safe through analyzing the quality of water supplied along the railway lines of Lanzhou Railway Administration.
Methods Using the health supervision and monitoring data of centralized water supplied in six train service depots of Lanzhou Railway Administration in 2006—2010 to produce statistical analysis.
Results The pass rates of total coliform bacteria colonies, coliforms and heat resistant organisms in water were 95% or more; the quality of toxicology, sensory properties and general chemical indexes of water in five years had not changed, the qualified rates of most indicators were maintained at 90%.
Conclusions The quality of water in the centralized water suppliers along the railway lines of Lanzhou Railway Administration was good.Strengthening dynamic management to ensure the quality and safety of water is necessary.
