Problems solved by technology

Therefore, fouling of alkaline precipitates (such as Ca(OH) 2 , Mg(OH) 2 etc.), long-term operation will inevitably lead to the blockage of the cathode gas diffusion layer and the increase of cathode polarization, which will increase energy consumption and reduce the life of the cathode

Abstract

The invention relates to a solid electrolyte electrolytic cell device using an anion exchange membrane. The solid electrolyte electrolytic cell device comprises an ion exchange membrane as well as an anode chamber and a cathode chamber arranged at both sides of the ion exchange membrane, wherein the anode chamber comprises an anode terminal plate, a porous anode support material and an anode catalytic layer; the cathode chamber comprises a cathode terminal plate and a porous cathode catalytic material and the ion exchange membrane material is the anion exchange membrane. By virtue of the solid electrolyte electrolytic cell device disclosed by the invention, the problem of scaling at an interface between the membrane and the electrode is avoided, the phenomenon of scaling of the ion exchange membrane is greatly retarded, the problem of blocking due to the scaling of the SPE (Solid Polymer Electrolyte) electrolytic cell is avoided and the stability and service life of the sewage treatment device are prolonged. The selection of the cathode catalytic material of the SPE electrolytic cell can be also broadened and the cost of the sewage treatment device can be significantly reduced.

Description

technical field [0001] The invention relates to the technical field of water treatment industry in the field of environmental protection, in particular to an electrolyzer device using an anion exchange membrane solid electrolyte. Background technique [0002] Many industrial wastewaters have poor biodegradability, and contain a large amount of ammonia, cyanide, phenols, pyridine, quinoline and many other inorganic and aromatic toxic and harmful substances, which are difficult to biodegrade. Electrochemical advanced oxidation is an effective method to treat such industrial wastewater. Electrochemical oxidation uses free radicals generated on the electrode surface (such as direct oxidation of hydroxyl radicals) or generated oxidants (such as indirect oxidation of hypochlorous acid), which can effectively oxidize and degrade water Organic Pollutants. In addition, the cathode can produce hydrogen by electrocatalytic reduction of protons in water at the cathode at a lower potent...
