Embodiment Construction

[0134] The implementation of the method in this case, the main steps are as follows:

[0135] 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 restrictor is inside the wastewater degradation reactor. The metal cage-shaped microwave irradiation airspace restrictor is a metal cage, and the structure of the metal cage is covered with holes or meshes. The function of the cage-shaped microwave irradiation airspace confinement device is to confine the microwave irradiation airspace inside it, thereby constructing a microwave weak radiation airspace between the outer wall of the cage-shaped microwave irradiation airspace confinement device and the inner wall of the reactor or microwave zero-irradiatio...

Abstract

The invention relates to a radiation source state self-inspection photocatalytic wastewater degrader 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 performing a plurality of steps for achieving the expansion goal of the device.

Description

technical field [0001] The invention relates to a method for expanding the capacity of a waste water degradation device for self-checking the state of a radiation source of photocatalysis, and belongs to the technical field of CO2F waste water 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 ...
