Meanwhile, the direction of the electrode is designed to be perpendicular to the direction of water flow, so that contact between liquid and the surface of the electrode is realized to the greatest extent, and therefore rapid and sufficient mass transfer is realized, and sufficient oxidative degradation of the liquid is promoted.

Further, the anode plates in the electrode module are two, the cathode plates are one, the anode plates and the cathode plates are arranged in parallel, the two anode plates are respectively positioned on two sides of the cathode plates, and holes which can pass through the non-conductive screws are respectively and correspondingly formed in the anode plates and the cathode plates; the upper ends of the anode sheet and the cathode sheet are respectively connected with an anode binding post and a cathode binding post through conductive screws, threads are arranged on the peripheries of the upper ends of the anode binding post and the cathode binding post, and the two binding posts are fixed on a horizontal mounting plate arranged outside through binding post nuts. The cathode electrode plate and the anode electrode plate are integrated into a group in a superposition combination mode by adopting the flat plate type electrode, and are assembled through the conductive screw and the non-conductive screw, so that the structure is simple and the disassembly is convenient.

Further, a plurality of through holes are formed in the periphery of the top surface of the mounting plate in a penetrating mode, a plurality of threaded holes are correspondingly formed in the top surface of the shell, and the mounting plate is fixed in the threaded holes through mounting nuts. After the whole electrode is integrated on the mounting plate, the mounting plate is fixed on the shell through the nut, and the mounting plate can be detached integrally during later replacement and maintenance.

Further, the cathode plate and the anode plate are in a grid shape, and the holes of the grid are in one of triangle, circle, diamond, rectangle, trapezoid and polygon. Electrode plates of different shapes are adopted according to the physical state of the actual treatment liquid, such as the particle size of suspended matters.

Further, a groove capable of being embedded with an O-shaped ring is formed in the shell at the bottom of the mounting plate. Used for sealing the joint between the mounting plate and the shell.
