[0002] An electrochemical reactor is a device or apparatus for realizing an electrochemical reaction. The electrochemical reactor is provided with two electrodes with different polarities. After power-on, the solution is electrolyzed under the action of the electrodes to obtain cathode and anode products.

Therefore, the anode structure is improved to improve the oxidation effect of the anode. However, for some organic pollutants that are difficult to oxidize and easy to reduce, when using electrochemical technology for treatment, obviously improving the anode oxidation effect is not the optimal solution. Therefore, the cathode reduction effect can be improved. At present, most of the reactors for the cathode adopt a flat plate material, and the mass transfer effect is general.
