摘要：

In this study, the O-3/Fenton system in a rotating packed bed (RPB) in tandem with coagulation process was applied to the advanced treatment of coal gasification wastewater (CGW). The removal of COD reached 35.4% in the O-3/Fenton@RPB process, and the total removal of COD rose to 47.8% after the effluent of the O-3/Fenton@RPB process was further treated with coagulation. The O-3/Fenton@RPB + coagulation tandem process also demonstrates good effect on enhancing biodegradation and removing color of the CGW, with the BOD5/COD and decolorization in the tandem process reaching 0.49 and 87.5%, respectively. In addition, an artificial neural network model was established to predict the mass transfer performance of the O-3/Fenton system in the RPB and exhibited a good predictability. The O-3/Fenton@RPB + coagulation tandem process shows the application potential in the advanced treatment of CGW.
