Embodiment Construction

[0131] The implementation of the method in this case, the main steps are as follows:

[0132] 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;

[0133] 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 connection in the sense of channel;

[0134] c. Extend and expand the size of the microwave weak radiation space or the microwave...

Abstract

The invention relates to a monitoring lamp source state photocatalytic wastewater degradation reactor expansion method, belonging to the technical field of wastewater treatment. The existing related background technique has the problems of difficulty in instantly knowing the functional state of the electrodeless lamp easily, magnetron corrosion by water invasion and secondary ozone inversion cross flow in the electrodeless lamp arrangement cavity (quartz tube cavity), incapability of well utilizing electrical charge characteristics of the catalyst, and the like. The invention aims to solve the problems. The method mainly comprises the following steps: introducing one end of an optical fiber to the periphery of the quartz tube so that the tip of the optical fiber points to the inner cavity of the quartz tube; enabling the other end of the optical fiber to be close to and point to a detection window of an ultraviolet intensity detection instrument; continuously supplying air to the quartz tube cavity region with a minitype air pump to counteract air leakage due to various regions, and keeping the positive pressure state of the air in the region to prevent water invasion accidents; hermetically isolating a waveguide tube with a microwave-permeable material to prevent the ozone inversion cross flow; finely intercepting the catalyst particles with a plurality of cascade-connected negatively-charged filter membranes; and expanding the capacity of the reactor, and the like.

Description

technical field [0001] The invention relates to a method for expanding the capacity of a photocatalytic wastewater degradation reactor for monitoring the status of a light source, 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 protec...
