Embodiment Construction

[0116] The implementation of the method in this case, the main steps are as follows:

[0117] 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 quartz tube is located inside the reactor, and the cage-shaped microwave confinement device is a cage-shaped metal component , the structure of the cage-like microwave confinement device has holes or meshes all over its structure, the function of the cage-like microwave confinement device is to confine the microwave irradiation space inside it, so that the outer wall of the cage-like microwave confinement device and the A microwave weak radiation space o...

Abstract

The invention relates to a capacity expansion method of a photocatalytic wastewater degradation reactor combined with the charged characteristic of a contact agent, and belongs to the technical field of wastewater treatment. In order to solve the problems in the relevant prior art that the loss of the contact agent exists; the microwave energy is wasted; a small amount of wastewater can be treated by using a reactor with a single tank; the moment at the end of a degradation reaction is difficult to distinguish; a contact agent agglomeration matter cannot be forcedly dissipated in situ; the agglomeration of the contact agent is not perceived in time; the charged characteristic of contact agent particles is not utilized well and the like, the method mainly comprises the following steps: tucking a microwave irradiation range by using a metal cage; bunching the rising bubble flows by using a horn barrel-shaped component; expanding the size of the reactor; strengthening the interception of the contact agent by using a hollow fiber membrane changed with negative electricity; forcedly dissipating the contact agent agglomeration matter via ultrasonic waves from the bottom of the reactor as well as incidentally cleaning a quartz tube at the same time; monitoring the reaction process by using an ozone sensor; automatically controlling relevant power supply switching mechanisms via electric sensing signals; and automatically detecting a main agglomeration inducement parameter.

Description

technical field [0001] The invention relates to a method for expanding the capacity of a photocatalytic wastewater degradation reactor that combines the charging characteristics of a catalyst, 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 shroud...
