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

Abstract

The invention provides a microwave coupling photo-catalytic wastewater degradation reactor with greatly expanded capacity of a single tank, 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 cylindrical component made of a metal material is vertically spanned inside the reactor in a suspending manner, and the upper area of the cavity pipe of the cylindrical component is separated by two metal meshes; an electrodeless ultraviolet lamp and a shield of the electrodeless ultraviolet lamp are moved to a position between the two metal meshes inside the cavity pipe with a quartz tube; a certain distance is remained between the outer wall of the quartz tube and the inner wall of the cavity pipe; and microwave radiation is limited in the area between the two metal meshes inside the cavity pipe. The structure is advantageous to intensify liquid circulation. According to the microwave coupling photo-catalytic wastewater degradation reactor, the problems can be solved comprehensively.

Description

technical field [0001] The invention relates to a microwave-coupled photocatalytic wastewater degradation reactor with greatly expanded capacity of a single tank, belonging 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. , a...
