METHOD FOR PROMOTING COKING WASTEWATER TREATMENT BY PHOTOCATALYTIC ELECTRODE COUPLED MICROBIAL FUEL CELL

摘要

A method for promoting coking wastewater treatment by a photocatalytic electrode coupled microbial fuel cell. A method of fixedly coating a stainless steel mesh with La-ZnIn₂S₄/RGO/BiVO₄ and silica sol is used to form a conductive catalytic composite membrane electrode, and the membrane electrode is used as an anode; HSO₃^- is added into coking wastewater in an anode chamber; a carbon stick is inserted into microorganisms in the anode chamber and is connected by means of a lead wire to form a circuit loop; and a halogen tungsten lamp is used as a light source acting on a catalytic electrode, thereby forming a system for treating coking wastewater by a photocatalytic electrode coupled microbial fuel cell.
