Cyanide-containing wastewater electrolysis reactor for packed bed

The utility model belongs to the technical field of reactors for treating cyanogen-containing wastewater, and particularly relates to a reactor for electrolyzing cyanogen-containing wastewater by a packed bed. Wherein the sealing cover is fixed at the top of the inner insulating tank body, an exhaust port is formed in the sealing cover, an upper water inlet and a lower water outlet are formed in the inner insulating tank body, the interior of the inner insulating tank body is divided into a water inlet sedimentation buffer area, a filling bed electrolysis area and a water outlet buffer area by a water outlet overflow plate and a water inlet overflow plate, and a plurality of groups of cathode and anode partition plates are arranged in the filling bed electrolysis area. Every two groups of cathode and anode partition plates are separated by an electrode partition plate, a semiconductor filling bed is arranged between each group of cathode and anode partition plates, an aeration device is arranged at the bottom
