Abstract：A combined process was developed for deep treatment of effluent from an industrial wastewater treatment plant,which involved a surface flow constructed wetland,a vertical flow constructed wetland,a subsurface constructed wetland and two stereoscopic ecolgical spaces.The results showed that the effluent of the combined process met with Quasi Class Ⅳ of the Environmental Quality Standards for Surface Water(GB 3838-2002)when HRT was 72 h,the influent COD,NH+4-N,TP and TN were respectively 21.9～41.2 mg·L-1,0.51～4.21 mg·L-1,0.06～0.31 mg·L-1 and 8.79～14.2 mg·L-1.It will provide a certain reference for the deep treatment of effluent from an industrial wastewater treatment plant.
