[0002] Wastewater electrolysis treatment refers to a method of applying the mechanism of electrolysis to convert harmful substances in the original wastewater into harmless substances through oxidation and reduction reactions at the anode and cathode respectively through the electrolysis process to achieve wastewater purification. The electrolytic cell is equipped with plates, which are generally made of ordinary steel plates. The electrolytic cell is divided into unipolar and bipolar types according to the way the plates are connected to the power supply. After power is turned on, under the action of the external electric field, the anode loses electrons to undergo an oxidation reaction, and the cathode gains electrons to undergo a reduction reaction. The wastewater flows through the electrolytic cell as an electrolyte, and oxidation and reduction reactions occur at the anode and cathode respectively, and the harmful substances are removed.
