Abstract: In an anode and cathode synergistic electrocatalytic system for wastewater treatment and an application, an electrode having a “dual function” is used as a cathode. The cathode and an anode are sequentially arranged in a crisscrossed and parallel mode and fixed into an electrode group. The electrode group is paced in a reaction tank which has an aeration device at the bottom thereof, separately connecting the cathode and the anode of the electrode group to a power supply. Electrocatalytic degradation is performed on wastewater. In the electrocatalytic degradation process, a synergistic electrocatalytic degradation effect of the anode and the cathode is achieved by the mutual coordination of heterogeneous electro-fenton of the cathode and oxidation of the anode. The cathode ad anode synergistic electrocatalytic process has a good wastewater treatment effect, high current efficiency, low energy consumption, and low operation and maintenance costs.
