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

Embodiment Construction

[0028] The implementation of the method in this case, its main steps are as follows:

[0029] a, a trumpet-shaped member made of metal is vertically suspended in the inner cavity of the reactor with its big head facing down, and the main body of the reactor is a reaction tank made of metal;

[0030] b. Vertically suspending the quartz tube with the electrodeless ultraviolet lamp installed in the upper airspace inside the cavity of the trumpet-shaped member;

[0031] c. The structural position above the quartz tube and the structural position below the quartz tube in the cavity of the horn-shaped component are separated by metal mesh, and a total of two pieces of metal mesh are involved, which are the upper piece of metal net and the lower piece of metal mesh, wherein the upper piece of metal mesh is adjacent to the upper port of the trumpet-shaped member or is flat with the upper port, and the upper and lower pieces of metal mesh are cut in the cavity of the horn-shaped member...

Abstract

The invention relates to a microwave coupling effect considered wastewater photocatalytic degradation reactor expansion method, and belongs to the technical field of wastewater treatment. A scheme in the invention aims to solve the problems comprising small reactor single-tank throughput, high operation repeating frequency, insufficient internal liquid cycle strength and the like in the present microwave photocatalytic degradation technologies against industrial wastewater containing organic pollutants on the premise of giving the consideration to microwaves and the photocatalytic coupling effect. The method of the scheme is characterized in that a set of mutual-cooperating metal components is arranged in the reactor to carry out forced isolation of a microwave irradiation airspace, the microwave irradiation is restricted in a cylindrical airspace allowing wastewater to flow and a bubble flow containing ozone to freely get in and out, and a volume expansion airspace having no microwave irradiation and allowing the design size to be greatly expanded is constructed between the surrounding border of the cylindrical airspace and the inner wall of the reactor. The arrangement mode of the metal components is in favor of the large cycle of the internal liquid.

Description

technical field [0001] The invention relates to a method for expanding the capacity of a photocatalytic wastewater degradation reactor in consideration of microwave coupling, 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...
