Abstract

The invention discloses a water-permeable electrode plate which comprises an integrally-formed pectinate anode and an integrally-formed pectinate cathode, wherein the pectinate anode is composed of multiple anodes arranged in parallel and anode tabs connected with the multiple anodes; the pectinate cathode is composed of multiple cathodes arranged in parallel and cathode tabs connected with the multiple cathodes; the pectinate anode and the pectinate cathode are interleaved in the opposite direction, so that the anodes and the cathodes are arranged alternately, thus forming a combined electrode group; and coating the anodes and the cathodes inside a water-permeable material. In the process that bubbles generated in the electrolysis process escape from the water-permeable material, the bubbles are cut by irregularly-arranged micro pores of the water-permeable material itself, thus reducing the diameter of the bubbles and improving the treatment effect of sewage; and the bubbles continually escape from the inside of the water-permeable material to the surface, and prevent the scaling phenomenon on the surface of the water-permeable material, thereby prolonging the service life of the electrode plate.

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...
