Simple pendulum motion electrode sewage treatment device

Abstract

The invention relates to a simple pendulum motion electrode sewage treatment device which comprises a sewage treatment tank, a rotating shaft is rotatably mounted at the upper part of the sewage treatment tank, two ends of the rotating shaft extend out of the sewage treatment tank and are connected with a simple pendulum type magnet magnetic needle assembly, and an electromagnet driving structure is arranged under the end part of the rotating shaft; and the part, positioned in the sewage treatment tank body, of the rotating shaft is connected with an electrode bracket; an electrode group is placed in the electrode bracket. By means of simple pendulum motion of the electrode group and relative immobility of sewage, short flow is reduced, concentration polarization is reduced, formation of dirt on the electrodes is slowed down, the distance between electrode plates is reduced, the organic matter pollution decomposition effect is improved, energy consumption is reduced, electromagnet repulsive force provides swing driving force when the mass block is located at the bottom, and the device has the advantages of simple structure, wide electrode application type, low manufacturing cost, low energy consumption and long service life.

Description

technical field [0001] The invention relates to a sewage treatment device, in particular to a single pendulum moving electrode sewage treatment device, which belongs to the field of sewage treatment. Background technique [0002] Electrocatalytic oxygen technology is a green chemical technology that uses special electrode plates to energize to generate hydroxyl radicals or other groups and free radicals with super oxidizing ability to decompose organic pollutants in the solution and convert them into harmless water and carbon dioxide. , suitable for refractory biodegradable industrial wastewater treatment. At present, the electrode plates of electrocatalytic oxidation devices commonly used in engineering are fixed in the reactor, and the fluid is moved rapidly relative to the electrodes by aeration or increasing the flow rate to make the pollutants fully contact with the electrode plates to improve the decomposition efficiency of organic pollutants. In addition, in recent ye...
