Embodiment Construction

[0119] The implementation of the method in this case, its main steps are as follows:

[0120] a, a metal trumpet-shaped component is suspended vertically in the inner cavity of the reactor with the big head facing down;

[0121] b. Vertically suspending the quartz tube with the electrodeless ultraviolet lamp installed in the upper airspace inside the cavity of the trumpet-shaped member;

[0122] 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, Outline a section of cylindrical airspace containing the quartz tube ...

Abstract

The invention relates to a microwave photocatalysis wastewater degradation reactor dilation method for integrating Coulomb repulsion action, and belongs to the technical field of wastewater treatment. The problems of extremely weak catalyst interception link, extremely small single-tank treatment amount of a reactor and difficult discrimination of degradation reaction terminal time and the problems that catalyst aggregations can not be intensively dissipated in situ, the catalyst aggregations can not be perceived in time, the charged characteristics of catalyst particles is not properly utilized, and the like exist in the related prior art. Aiming at the problems, the microwave photocatalysis wastewater degradation reactor dilation method comprises the following main steps of: limiting a microwave radiation region; bunching bubble flows, and guiding the bubble flows into an important degradation reaction region; intensifying catalyst interception by using hollow fiber membrane with negative electric charges; intensively dissipating the catalyst aggregations in situ by using ultrasonic waves emitted from the bottom of the reactor, and incidentally cleaning a quartz tube; monitoring reaction progress by using an ozone sensor, and automatically switching off a relative power supply when reaching a degradation terminal; and actively warning a catalyst aggregation tendency.

Description

technical field [0001] The invention relates to a method for expanding the capacity of a microwave photocatalytic wastewater degradation reactor integrating Coulomb repulsion, 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 attracted much attention 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 ...
