[0002] The electrochemical treatment of sewage is to apply the basic principle of electrolysis, so that harmful substances in the wastewater are respectively oxidized and reduced on the anode and cathode during the electrolysis process and successfully mineralized into harmless inorganic substances to realize the purification of the wastewater. The BDD (boron-doped diamond) electrode module is widely used in the electrochemical treatment of sewage. However, some installation methods of the BDD electrode module are unreasonable, which will cause the bubbles generated during the electrolysis of sewage and wastewater to adhere to the electrode plates, resulting in the inability of the sewage and wastewater to be fully electrolyzed and mineralized, and the treatment effect is relatively poor. Some reaction devices of the BDD electrode module add a stirring device or an aeration device inside to make the sewage and wastewater flow through the space between the electrode plates sufficiently and quickly, so as to fully electrolyze and mineralize the sewage and wastewater. However, this method will increase the cost. Summary of the Utility Model
