铁路货车车辆段综合污水处理工艺设计

Design of Wastewater Treatment in a Railway Wagon Depot

铁路货车车辆段排放的工业污水含油量较高,BOD/COD比值不高,直接采用生化处理并不合适。因此,工业污水应经预处理与生活污水相混合,然后进行生化处理,再辅以深度处理,最终出水水质可满足达标排放或者回用标准。

Industrial effluent drained by a railway wagon depot contains prtroleum pollutants,and the value of BOD/COD is not large enough, which makes it not suitable to be treated by biochemical process. So, the industrial effluent should be pretreated first, and mixed with domestic sewage, then enter biochemical process and advanced treatment,the quality of the water sent out can reach the standard to be discharged or reused.
