Large-throughput ultraviolet photocatalytic wastewater degradation reactor adopting microwave excitation light source

Abstract

The invention relates to a large-throughput ultraviolet photocatalytic wastewater degradation reactor adopting a microwave excitation light source, and belongs to the technical field of wastewater treatment. A scheme adopted in the invention aims at the problems comprising useless energy dissipation caused by a case that a quantity of microwave energy is absorbed by wastewater, small wastewater throughput of a single tank of a reactor, insufficient internal liquid cycle intensity and the like in present electrodeless ultraviolet photocatalytic degradation technologies against industrial wastewater containing organic pollutants. In the scheme, electrodeless ultraviolet lamps are placed in a caged non-opaque metal microwave restraint to restrain microwaves and repress the useless dissipation of the microwaves, an ultraviolet-transmitting quartz tube used for gas-liquid isolation is arranged between the microwave restraint and the wastewater, and the quartz tube is arranged in the upper portion of the chamber tube of the suspending and vertical cylindrical member of the inner cavity of the reactor. The scheme solves all the problems.

Description

Technical field [0001] The invention relates to a large-capacity ultraviolet photocatalytic wastewater degradation reactor adopting a microwave excitation light source, 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 publication number CN102260003A uses microwave as the excitation source to excite the electrodeless ultraviolet lamp to emit ultraviolet rays, and irradiate the suspension liquid doped with photocatalyst titanium dioxide into the liquid. The electrodeless ultraviolet lamp is protected by a quartz tube. , An air pump cont...

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 single-tank wastewater treatment. Wastewater photochemical catalytic degradation reactor, and the structure of the new reactor should also be able to piggyback and strengthen the relatively large-scale circulation of the liquid inside the reactor
