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. The three-dimensional electrode electro-catalytic oxidation reactor comprises a container and a power supply device, wherein the container is provided with a water inlet and a water outlet. The container is internally provided with an electrode group; the electrode group comprises a plurality of positive electrodes and a plurality of negative electrodes; the positive electrodes and the negative electrodes are same in number and uniformly arranged at staggered intervals; zeolite particles are added in the liquid in the container and used as a third electrode; and the power supply device is conductively connected with the positive electrodes and the negative electrodes of the electrode group. The three-dimensional electrode electro-catalytic oxidation reactor has the advantages as follows: 1, the positive electrodes and the negative electrodes obtain electric power, so that H ions and O ions are decomposed from sewage liquid, therefore the zeolite particles can be formed into a tiny primary cell, and the tiny primary cell is used for converting the H ions and the O ions into OH hydroxyl radical ions; and 2, the positive electrodes and the negative electrodes obtain the electric power, so that the zeolite particles play a particle electrode effect and exert an ion conversion effect so as to generate a lot of OH hydroxyl radical ions on the peripheral surfaces of the electrodes and in the liquid.

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
