Embodiment Construction

[0027] The implementation of the method in this case, the main steps are as follows:

[0028] a, use a metal cage-shaped microwave irradiation airspace confinement device to wrap the quartz tube with an electrodeless ultraviolet lamp inside, so that the quartz tube is inside the cage-shaped microwave radiation airspace confinement device, and the cage-shaped The overall structural position of the microwave irradiation airspace restrainer is inside the wastewater degradation reactor. The metal cage-shaped microwave irradiation airspace restrainer is a metal cage. The function of the cage-shaped microwave irradiation airspace restrainer is It confines the microwave irradiation space within it, thereby constructing a microwave weak radiation space or a microwave zero radiation space between the outer wall of the cage-shaped microwave irradiation space constraint and the inner wall of the reactor;

[0029] b. Probe the waveguide originating from the magnetron into the interior of ...

Abstract

The invention relates to a method for expanding the capacity of a microwave photo-catalytic coupling wastewater degradation device, and improving the internal circulation, and belongs to the technical field of wastewater treatment. On the premise of taking the microwave and photo-chemical catalytic coupling effect into consideration, the reactor aims at 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. The method comprises the following steps of forcibly separating and distributing the microwave radiation area inside the reactor by adopting a metal cage to lead a coupling catalytic degradation effect to perform in the metal cage; maintaining a space without microwave radiation between the outer wall of the metal cage and the inner wall of the reactor; and erecting a flared component which is used for guiding and intensifying liquid circulation right below the metal cage. According to the method, the designed capacity of the reactor is permitted to be greatly expanded, and formation of a powerful internal liquid circulation can be facilitated.

Description

technical field [0001] The invention relates to a method for expanding the capacity of a microwave photocatalytic coupling wastewater degradation device with improved 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 prot...
