Three-dimensional electrode electro-catalytic oxidation reactor for degrading sewage

Abstract

The invention discloses a three-dimensional electrode electro-catalytic oxidation reactor for degrading sewage, which comprises a container and a power source device, wherein the container is provided with a water inlet and a water outlet; an electrode assembly is arranged in the container, and comprises a plurality of positive electrodes and a plurality of negative electrodes, which are same in number and uniformly arranged at intervals in a staggered way; liquid in the container is added with zeolite particles serving as third electrodes; and the power source device is electrically connected with the positive and negative electrodes of the electrode assembly. The three-dimensional electrode electro-catalytic oxidation reactor has the advantages that: 1, the positive and negative electrodes acquire electric energy, so that sewage liquid is degraded into H ions and O ions, the zeolite particles can form small primary batteries, and the small primary batteries convert the H ions and O ions into OH hydroxyl radical ions; and 2, the positive and negative electrodes acquire electric energy, and the zeolite particles have the particle electrode function and ion conversion function, so that massive OH hydroxyl radical ions are generated on the peripheries and surfaces of the electrodes and in the liquid.

Description

technical field [0001] The invention relates to a three-dimensional electrode electrocatalytic oxidation reactor for degrading sewage. Background technique [0002] A three-dimensional electrode electrocatalytic oxidation reactor, including cathode and anode. In addition to selecting more suitable cathode and anode electrode materials, appropriate electrode spacing, electrode shape, structure, arrangement, area and other factors for this kind of reactor, finding a particle material suitable as a three-dimensional electrode is a three-dimensional electrode electrocatalytic oxidation reactor. The most important, the most important and the most crucial point of being able to exert higher performance. [0003] At present, most three-dimensional electrodes use activated carbon or modified carbon materials as three-dimensional electrode particles. Although it has the advantages of a wide range of applications, many sources of materials, and relatively low prices, it also has the...

AI Technical Summary

Problems solved by technology

Although it has the advantages of a wide range of applications, many sources of materials, and relatively low prices, it also has the following disadvantages: 1. The pertinence is not strong, and its efficiency is low when certain substances in special sewage are high; 2. Because the surface hardness of the particles is very low, it is easy to be damaged during the reaction process, making the particles smaller and losing electrical activity; 3. Because of its small specific gravity, it is easy to float out of the liquid surface and be lost or mixed into treated water to increase, such as sewage The difficulty and cost of design and manufacture of treatment equipment also increases the failure rate of equipment; 4. Although carbon particles have no secondary pollution advantages after being discarded, they have no use value and increase the cost of sewage treatment
