Abstract

The invention discloses a water permeable battery lead plate. The water permeable battery lead plate comprises an integrally-formed pectination anode comprising a plurality of parallel anodes and an anode lug connected with the plurality of anodes, and an integrally-formed pectination cathode comprising a plurality of parallel cathodes and a cathode lug connected with the plurality of cathodes, wherein the pectination anode and the pectination cathode are spaced oppositely so as to enable the plurality of anodes and cathodes to be arranged at intervals to form a combined electrode group, and the anodes and the cathodes are wrapped inside the water permeable material. When bubbles generated in the electrolysis process escape from the water permeable material, the bubbles are cut by irregularly arranged micropores of the water permeable material, so that the diameter of the bubbles is reduced, and the sewage treatment effect is improved; as the bubbles constantly escape from the interior of the water permeable material to the surface, scaling on the surface of the water permeable material is avoided, and the service life of the battery lead plate is prolonged.

Description

technical field [0001] The invention relates to an electrode plate, in particular to a water-permeable electrode plate used in an electrolytic air flotation sewage treatment device. Background technique [0002] Air flotation technology is one of the commonly used sewage treatment technologies. Its principle is to use special electrode materials to electrolyze sewage with low energy consumption. The tiny bubbles generated in the process adhere to the pollutants in the water and float together to remove them; the diameter of the bubbles produced is in About 10-100 microns, it is smoky in water and has a strong air flotation efficiency; electrolytic air flotation usually uses insoluble electrodes, commonly used are stainless steel, graphite, lead dioxide, metal oxide titanium-based electrodes, etc., usually The electrolytic cell is installed at the bottom of the water treatment pool, and the water slowly flows through the electrolytic cell, and the air bubbles are adsorbed aft...
