地铁交通污水排放工程的节能节水技术应用研究

Application of Energy Saving Technology in Subway Traffic Sewage Discharge Project

针对当前的地铁交通污水排放体系全面性差的问题,提出将节水节能技术应用到污水排放体系建设中,对污水特性和污水排放工程问题进行分析,分析结果表明,地铁交通污水主要来源于消防废水、生活污水和雨水;地铁交通污水排放设计没有具体的规范;城市的地势偏低或城市中不同地区有明显的高低差,易致使地铁排水倒灌;路基路面结构与材质不良,容易导致路面积水,使路面积水向地铁内滴入或涌入;依据地铁交通污水排放对地铁运行和生态环境的影响,构建基于节能节水技术的地铁交通污水排放体系。

Given the poor comprehensive treatment ability of sewage in subway traffic system,this study applied thwater saving technology in the construction of sewage disposal systemto analyze the sewage discharge characteristics problems. The analysis results show that the Metro wastewater mainly comes from the firefighting wastewater,sewage and rainwater.There＇s no specific regulations for sewage disposal design in subway and different regions of thelow - lying city or city has obviousdifference of height to the subway fromthe pavement structure and subgrade drainage; bad material,easy to cause the surface the surface water influx to drip into the subway or subway traffic ; Based on the effects of sewage ologcal environment,this study builds the energy saving and water saving technology for Metro sewage discharge system.
