北京地铁车辆段及维修基地污水处理技术及其应用

Sewage treatment technology of Beijing metro depots and maintenance bases

根据北京地铁车辆段及维修基地污水水质特点,探讨现有污水处理工艺。将气浮除油及A;O+MBR处理技术应用于北京地铁车辆段污水处理项目现场,其出水指标达到国家污水处理标准,同时实现中水资源回收利用,以期为北京地铁节能降耗工作的开展提供新思路。

According to the sewage quality characteristics of Beijing metro depots and maintenance bases,the existing sewage treatment technology is discussed.The gas adsorption uncoiling technology and A;O+MBR treatment technology were applied to the sewage treatment project site of Beijing metro car depots.The effluent index reached the national sewage treatment standard,and the water resource was recovered and utilized at the same time,in order to provide a new idea for the work of energy conservation and consumption reduction of Beijing metro.
