Aiming at the phenomenon of anodic polarization and the mechanism thereof, the service life of the carbon anode is prolonged, and the occurrence of electrode polarization is reduced or the polarization is effectively eliminated. In general, the anode effect is treated by a high-voltage back-flushing method, that is, after the anode effect occurs in the electrolysis process, the production power supply is switched to a high-voltage power supply, and a high voltage is applied to the anode, so that the fluorocarbon film on the electrode is automatically separated.
