Embodiment Construction

[0132] The implementation of the method in this case, the main steps are as follows:

[0133] a, The electrodeless ultraviolet lamp located in the quartz tube is covered by a cage-shaped microwave confinement device made of metal, so that the electrodeless ultraviolet lamp is inside the cage-shaped microwave confinement device, and the overall structural position of the cage-shaped microwave confinement device It is also inside the quartz tube, which is a component used for gas-liquid phase isolation and screen protection. The cage-shaped microwave confinement device is a cage-shaped metal component, and the cage-shaped microwave confinement device The function is to confine the microwave radiation inside;

[0134] b. Suspending the quartz tube with the electrodeless ultraviolet lamp wrapped by the cage-shaped microwave confinement device made of metal material, it is suspended in a region with a relatively small diameter of the cavity inside the cavity of a trumpet-shaped com...

Abstract

The invention relates to a lamp source state self-inspection ultraviolet catalytic 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 ozone inversion cross flow in the quartz tube cavity for electrodeless lamp shielding, 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; and finely intercepting the catalyst particles with a plurality of cascade-connected negatively-charged filter membranes, and the like.

Description

technical field [0001] The invention relates to a method for expanding the capacity of an ultraviolet photocatalytic wastewater degradation reactor for self-inspection of the state of a lamp 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 ...
