Internal-liquid-circulation-reinforced high-treatment-capacity reactor for wastewater photochemical degradation

Abstract

The invention relates to an internal-liquid-circulation-reinforced high-treatment-capacity reactor for wastewater photochemical degradation, belonging to the technical field of wastewater treatment The existing electrodeless ultraviolet catalytic degradation technique for organic-substance-containing industrial wastewater has the problems of inutile energy dissipation due to high absorption amount of microwave energy by the wastewater water body, overlow single-tank wastewater treatment capacity of the reactor, insufficient internal liquid circulation strength and the like. The scheme provided by the invention aims to solve the problems above. According to the scheme provided by the invention, an electrodeless ultraviolet lamp is arranged in a metal cage-shaped photopermeable microwave restriction device into which microwaves are introduced, so that inutile dissipation is inhibited by restricting the microwaves; meanwhile, in the structure, an ultraviolet-permeable quartz tube for gas-liquid isolation is arranged between the microwave restriction device and the wastewater body; and a flared component for reinforcing liquid circulation is arranged right below the quartz tube. The scheme provided by the invention totally solves the problems above.

Description

technical field [0001] The invention relates to a large-capacity reactor for photochemical degradation of wastewater with enhanced internal liquid circulation, and belongs to the technical field of CO2F wastewater treatment. Background technique [0002] Microwave photocatalytic degradation treatment technology, as an effective harmless treatment technology for industrial wastewater containing organic pollutants, has developed rapidly in recent years. [0003] Regarding the microwave photocatalytic degradation technology, as an example, refer to the Chinese patent application with publication number CN102260003A. [0004] The Chinese patent application with the publication number CN102260003A uses microwaves as the excitation source to excite the electrodeless ultraviolet lamp to emit ultraviolet rays, and irradiates the suspension mixed with photocatalyst titanium dioxide inside the liquid. The electrodeless ultraviolet lamp is shrouded and protected by a quartz tube. , an...

Problems solved by technology

[0009] The technical problem to be solved by the present invention is to develop a new type of microwave oven that can solve the above-mentioned problems in view of the shortcomings in the above-mentioned CN102260003A application, that is, the unsatisfactory utilization of microwave energy and the small amount of actual wastewater treatment in a single tank. Wastewater photochemical catalytic degradation reactor, and the structure of this new type of reactor with improved single-tank wastewater treatment capacity should also be able to piggyback and strengthen the relatively large-scale circulation of the liquid inside the reactor
