High-capacity wastewater microwave photo-catalytic coupling degradation device for intensifying internal circulation of liquid

Abstract

The invention relates to a high-capacity wastewater microwave photo-catalytic coupling degradation device for intensifying internal circulation of liquid, and belongs to the technical field of wastewater treatment. On the premise of taking the coupling effect into consideration, the reactor aims at, in a package manner, solving the problems of small wastewater treatment amount of a single tank of a reactor, high repeated operation frequency, insufficient internal liquid circulating strength and the like, which exist in the existing technology of microwave photo-catalytic degradation to organic pollutant industrial wastewater. A metal cage is arranged in the reactor, an electrodeless ultraviolet lamp and a shield of the electrodeless ultraviolet lamp are coated in the metal cage with a quartz tube, a certain distance is maintained between the outer wall of the quartz tube and the inner wall of the metal cage, so that a microwave and photo-chemical coupling effect area is formed between the outer wall of the quartz tube and the inner wall of the metal cage; and the microwave radiation effect is blocked in the area between the outer wall of the metal cage and the inner wall of the reactor, and a flared cylindrical component used for intensifying liquid circulation is erected right below the metal cage. The high-capacity wastewater microwave photo-catalytic coupling degradation device is advantageous to solve the problems.

Description

technical field [0001] The invention relates to a microwave photocatalytic coupled degradation device for large-capacity wastewater with enhanced liquid internal 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 qua...

Problems solved by technology

[0010] In addition, in the scheme shown by CN102260003A, the inside of the reaction tank is filled with rising air bubbles, and the contribution to the relatively large-scale circulation of the liquid inside the reaction tank is slightly insufficient; As articulated in its detailed description, there is virtually no observable effect on corresponding small-size, low-capacity devices
