Embodiment Construction

[0119] The implementation of the method in this case, the main steps are as follows:

[0120] 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;

[0121] 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 reactor capacity expanding method for waste water photocatalysis degradation and catalyst interception mechanism upgrade, and belongs to the field of waste water treatment technology. The invention solves a series of problems existed in the related art, such as catalyst loss, smaller single tank capacity, difficult distinguishing of degradation terminal point time, hard utilization of catalyst charged property, lack of supervision step electrodeless lamp, deficiency of quartz chamber water inrush prevention measure or the like. The invention mainly comprises the following steps: restraining microwave for irradiation of the assigned area only; expanding the reactor dimension; intercepting the catalyst by the externally cascaded three-grade backwashing type filter step-by-step, wherein, the end filter membrane is the filter membrane charged with negative electricity; exploring the core space of the reactor by fiber, thereby supervising the function state of the electrodeless lamp; supervising the reaction process by the ozone sensor, and automatically closing the related power supply when arriving at the degradation terminal point; actively self-checking the agglomeration tendency of the catalyst; or the like.

Description

technical field [0001] The invention relates to a reactor expansion method for upgrading a catalyst interception mechanism for photocatalytic degradation of wastewater, 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 qu...
