Computer Assisted Design of Electro-Fenton Reactor to Improve the Pollutants Degradation Ability

Abstract

The traditional electro-Fenton catalysis is performed in batch reactors or flow-by reactors. In these types of reactors, electro-Fenton rection suffers low current efficiency and high energy consumption caused by limited electrode/solution catalytic interface and negative electrostatic repulsion effect. In this work, a flow-through type electro-Fenton reactor was designed by implanting the biomass derived self-supporting cathode and cheap titanium mesh. The flow-through reactor has three advantages: Flowthrough three-dimensional electrodes can lower the energy consumption and operating costs; Short distance between cathode and anode is conducive to electron transfer; High-porosity electrode materials can improve mass transfer of pollutants. The effects of electrode assembly pattern and flow direction on pollutants removal efficiency were investigated to optimize the electro-Fenton performance of the flow-through type reactor.
