Abstract: This study recommends FBR-Fenton/GAC process to be a feasible technology for ROC treatment, with high COD removal efficiency (72 %) and good performance stability. The carrier selection study proposed first time the three main mechanisms involved in FBR-Fenton/GAC process, including homogenous Fenton reaction, GAC adsorption, and GAC/H2O2 catalytic reaction. Also, in-situ GAC regeneration along the FBR-Fenton/GAC process was proved first time, with more than 90 % regeneration of GAC’s adsorption capacity during long-term operation of the process, which could enhance process effectiveness and prolong GAC lifetime. A novel integrated CFD-kinetic model framework was then proposed to be a promising numerical tool for simulating the FBR-Fenton/GAC process. The model was able to accurately predict the process performance by considering the interactions between the process and reactor variables. This modeling study would contribute greatly to the future real-time process control and system automation.
