▎ 摘　　要

NOVELTY - A fast electrocatalytic oxidation sewage treatment system based on boron-doped diamond mesh electrodes and boron-doped graphene mesh electrodes comprises more than or equal to 1 composite electrode (N), electrolytic cell and power supply, and the composite electrode is located in the electrolytic cell. Each of the composite electrodes comprises boron-doped diamond mesh electrode and boron-doped graphene mesh electrode arranged at intervals, the boron-doped graphene mesh electrode as negative electrode, the boron-doped diamond mesh electrode as positive electrode, and the positive and negative electrode are connected with the power supply. USE - Fast electrocatalytic oxidation sewage treatment system based on boron-doped diamond mesh electrodes and boron-doped graphene mesh electrodes. ADVANTAGE - The boron-doped diamond mesh electrode is used as a positive electrode, and the boron-doped graphene mesh electrode is used as a negative electrode, when only one composite electrode is used, the fading time of simulated sewage degrading 30 mg/L methyl orange is 30 seconds, the degradation speed is 6.7mg/second, and the sewage can be treated rapidly, and environmentally-friendly with low consumption.
