Preparation of photoelectric integrated catalytic electrode and application of photoelectric integrated catalytic electrode in degradation of antiviral drug wastewater

The invention discloses preparation of a photoelectric integrated catalytic electrode and application of the photoelectric integrated catalytic electrode to antiviral drug wastewater degradation, and relates to the technical field of sewage purification and wastewater resource utilization. The composite catalytic electrode comprises a CMO electro-catalytic electrode and a WCN photocatalytic electrode, and nickel foam is placed between the CMO electro-catalytic electrode and the WCN photocatalytic electrode to form the composite catalytic electrode with a sandwich structure; the CMO electro-catalysis electrode is prepared by taking CuMn2O4 particles as a catalyst material through electro-deposition and heat treatment; the WCN photocatalytic electrode is prepared by adhering sodium tungstate, melamine and formaldehyde to a substrate through PVP (Polyvinyl Pyrrolidone), drying and calcining. The composite catalytic electrode is coupled with the photoelectric biological Fenton reaction, so that the acyclovir in t
