铁路中小站段污水处理匹配技术浅析

铁路通车里程迅速增加，铁路中小站段随之增长。站段内污水排放达不到国家排放标准而引起的环境恶化事例屡见不鲜。作者通过现场调研和资料查询，针对中小站污水排放量小、浓度较低的特点，综合分析了厌氧生物处理系统、SBR法等几种常用铁路污水处理工艺，对铁路水处理技术的发展具有一定的指导意义。

Research on Matching Technology for Wastewater Treatment of Moderate and Small Railway Stations

With the growth of railroad traffic mileage rapidly, the moderate and small stations increase. Because the drainage quality could not reach relevant national standard, deterioration of the environment see not fresh. Based on the on-site investigation and information search, the author analyzes the anaerobic biological treatment systems, SBR and so on under the conditions of small quantity and low concentrations of pollutants of wastewater from moderate and small stations. The paper can give some guidance to the development of water treatment technique.
