摘　　要：介绍了一套合流溢流污水处理装置的工艺流程、单元设计及其主要特点;对SS、CODCr、TP和浊度分别为170～700mg/L、130～650 mg/L、1.2～6 mg/L和150～330 NTU的合流溢流污水的中试研究表明,该装置对合流溢流污水具有良好的处理效果,SS、CODCr、TP和浊度平均去除率分别超过84%、68%、78%和79%.A set of devices was developed for control of the municipal combined sewer overflows , and in this paper the process flow, operation unit design and the overall feature of this facility is presented. The inflow wastewater has parameters of 170~700mg/L, 130~650mg/L, 1.2～ 6 mg/L and 150~330 NTU for SS, COD_ Cr , TP and turbidity respectively. The experimental results indicated that this device has good treatment effects, the average removals of the SS, COD_ Cr , TP and turbidity reached 84%, 68%, 78% and 79% respectively.
