The coking wastewater electrolysis unit comprises a tank body, wherein a support frame which is fixedly connected with the tank body is arranged in the tank body; an anode plate and two cathode plates are vertically arranged on the support frame; the anode plate is arranged between the two cathode plates; theanode plate and the cathode plates are connected with an external power supply; a plurality of carrier rods filled with composite catalysts are distributed between the anode plate and the cathode plates; the plurality of carrier rods are suspended on the top of the tank body through a lifting plate; and a plurality of spray pipes are arranged on the support frame. According to the coking wastewater electrolysis unit disclosed by the invention, the plurality of spray pipes are arranged in the electrolysis unit and distributed on two sides of the cathode plates and the anode plate, and electrodeplates in the electrolysis unit are subjected to backwashing by utilizing the wastewater subjected to electrolytic filtering, dirt attached onto the surface of the electrode plate is fully cleaned, and the service life of the electrode plate is prolonged. Moreover, the back-washing water is the treated wastewater, recycling is realized, the waste and pollution of water resources are reduced, andthe cost is saved.
