Expansion method of microwave photocatalytic wastewater degradation device with improved catalyst interception link

Abstract

The invention relates to a capacity expansion method for a microwave photo-catalytic waste water degradation device with further improvement of a catalyst interception link, belonging to the technical field of waste water treatment. In the related prior art, the problems of loss of a catalyst, smaller single-tank waste water treatment capacity of a reactor, high frequency of repeated operations, difficulty in distinguishing endpoint time of degradation reaction, incapability of realizing in-situ strong dissipation of a catalyst aggregate, incapability of timely noticing catalyst aggregation and the like occur, and the invention aims at solving the series of the problems in a one-package manner. The method adopting the scheme mainly comprises the following steps of: partitioning a microwave radiation airspace; greatly extending and expanding the size of the reactor; beaming a bubble flow to enable the bubble flow to release to a focus degradation reaction area in a centralized manner; using an external cascaded filter to finely intercept catalyst micro-particles; using ultrasonic waves emitted from a depression at the bottom of the reactor to perform in-situ strong dissipation on the catalyst aggregate, and simultaneously cleaning a quartz tube; using an ozone sensor to sense a degradation endpoint, and automatically closing a related power supply at the endpoint; automatically detecting main incentive parameters of catalyst aggregation; and the like.

Description

technical field [0001] The invention relates to a method for expanding the capacity of a microwave photocatalytic wastewater degradation device with improved catalyst interception links, 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...

Problems solved by technology

[0046] Based on the structure of the CN102260003A scheme, during its operation, the water pump that fills the reactor cavity with waste water cannot judge whether the water level inside the reactor is high or low, and the operator can only rely on experience or visual inspection to turn off the water pump that fills the waste water in time Motor, if the experience is wrong or the visual response is not timely enough, it is easy to overflow the reactor due to excessive filling of waste water, which will cause unnecessary trouble; The membrane module pumps water outward. Without knowing the water level inside the reactor, the timing of shutting down the pump can only be judged based on experience or visual inspection. This operation is obviously unreliable, and it is very easy to make mistakes due to experience or visual inspection. If the response is not timely, the water pump cannot be shut down in time, and this kind of dry pumping and idling can easily cause the motor of the water pump to burn out. This problem cannot be ignored. This is the fourteenth problem.
