Device and method for enhancing magnetic resin desorption

Abstract

The invention discloses a device and a method for enhancing magnetic resin desorption, and belongs to the field of resin regeneration. According to the invention, the first silicon-based hoop is longitudinally arranged outside the reaction zone of the device body, the second silicon-based hoop is transversely arranged outside the precipitation zone, and new-hole electron pairs are formed by utilizing the silicon-based materials under the irradiation of natural sunlight, so that a circulating alternating magnetic field is generated in the reaction zone and the precipitation zone; therefore, thedesorption efficiency of ammonia nitrogen is improved, the usage amount of desorption liquid is reduced, and the salt content in discharged water is reduced; meanwhile, the magnetism of the desorbedmagnetic resin is weakened under the action of an external magnetic field, mutual attraction force is reduced, the magnetic resin cannot be gathered to block a pipeline, a magnetic field is used for pushing magnetic resin particles to disturb to replace traditional mechanical stirring, and the resin crushing probability is reduced.

Description

technical field [0001] The invention belongs to the field of resin regeneration, and more specifically relates to a device and method for strengthening magnetic resin desorption. Background technique [0002] Magnetic resin adsorption method is widely used in the treatment of low-concentration ammonia nitrogen wastewater. Compared with other treatment methods, resin adsorption has the advantages of stable processing capacity, high processing efficiency, and no chemical addition. However, in the engineering practice of magnetic resin to treat wastewater, generally the resin will be stirred in the desorption tank after the adsorption is completed, and at the same time, the pollutants will be desorbed with salt water. Decreased adsorption efficiency, increased salt content in drainage, and mechanical agitation lead to problems such as broken magnetic resin. [0003] For example, the application number 200820237941.7, the application date is December 31, 2008, a Chinese utility...

Problems solved by technology

[0007] Aiming at the problems of resin accumulation, pipe blockage, and desorption adsorption efficiency reduction in the magnetic resin desorption process in the prior art, the present invention provides a device and method for strengthening magnetic resin desorption, by vertically setting There is a first silicon-based enclosure, and a second silicon-based enclosure is arranged laterally outside the precipitation area. These silicon-based materials are used to form new hole-electron pairs under natural sunlight, so that the reaction area and the precipitation area are generated. Circulating alternating magnetic field, so as to improve the desorption efficiency of ammonia nitrogen, reduce the amount of desorption liquid used, and reduce the salt content in drainage; at the same time, the magnetism of the desorbed magnetic resin is weakened under the action of an external magnetic field, and the mutual attraction decreases. It will accumulate and block the pipeline, and use the magnetic field to push the magnetic resin particles to disturb, thus replacing the traditional mechanical stirring and reducing the probability of resin breakage
