NOVELTY - Method for in-situ sustained release of Fenton's catalyst based on double anodes Electro-Fenton reactor comprises double anodes. The double anodes include inert electrode anode and iron anode, the cathode is located between the double anodes, the current value of double anodes can be independently adjusted, and the sum of current values of double anodes is equal to the applied surface of cathode, applying high current on the cathode surface by the cathode to generate reduction reaction in-situ to generate hydrogen peroxide (H2O2), generating catalyst Fe2+(ferrous ion) in situ at the iron anode oxidation, at the same time controlling the current ratio of inert electrode anode and iron anode to reduce the current on the iron anode to achieve the purpose of in-situ sustained release of Fenton catalyst under the premise of ensuring the efficient generation of hydrogen peroxide. USE - The method is useful for degrading organic pollutant including f phenols, heterocyclic compound, benzene ring compound, medicine compound and/or agrochemical chemical compound by electro-Fenton (claimed). DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for filter-type double-anode electric Fenton reactor. DESCRIPTION OF DRAWING(S) - The drawing shows schematic representation of the filter-type double-anode electric Fenton reactor.
