Embodiment Construction

[0118] The implementation of the method in this case, the main steps are as follows:

[0119] 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 confinement device is inside the reactor. The metal cage-shaped microwave irradiation airspace confinement device is a metal cage, and the metal cage itself is covered with holes or meshes;

[0120] b. Probe the waveguide originating from the magnetron into the reactor, and connect the end of the waveguide protruding into the reactor with the inner cavity of the metal cage. The communication refers to microwave Connection and penetration in the sense of channel;

[0121] c. Extend and expand the size of the microwave weak radiation space or the microwav...

Abstract

The invention relates to a photocatalysis waste water degradation reactor capacity expanding method with improved intermedium recycling step, and belongs to the field of waste water treatment technology. Compared to the related technology, the invention solves a series of problems, such as wasted microwave energy, small single pot waste water treating amount, lost catalyst, difficultly distinguished degradation terminal point, inefficient utilization of charged characteristics of catalyst, lacked real time supervision step of electrodeless lamp function state, lacked quartz chamber water inrush prevention measure, or the like. The method mainly comprises the following steps: restricting the microwave irradiation spatial domain with metal cages for facilitating greatly capacity expanding of the reactor; intercepting catalysts step by step with an externally cascaded three-level backwashing type filter, wherein, the end filter membrane is changed into a filter membrane charged with negative electricity; dissipating catalyst agglomerated objects at the original positions using supersonic wave generated from the bottom of the reactor, and simultaneously cleaning quartz tubes; sensing the degradation terminal with a ozone sensor and automatically turning off related power supplies at the degradation terminal point; exploring the core space of the reactor by fiber, thereby actively supervising the function state of the electrodeless lamp.

Description

technical field [0001] The invention relates to a method for expanding the capacity of a photocatalytic wastewater degradation reactor with improved medium recovery links, 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 by a...
