Dilation method of high-frequency ultrasound combined anti-adhesion photo-catalytic wastewater degradation reactor

Abstract

The invention relates to a dilation method of a high-frequency ultrasound combined anti-adhesion photo-catalytic wastewater degradation reactor and belongs to the technical field of wastewater treatment. The relevant prior art has the problems that the microwave energy is wasted, the wastewater treatment capacity of a single tank is low, the accelerant is lost, the degradation endpoint is hard to distinguish, the accelerant agglomerates cannot be scattered in root position, accelerant agglomeration cannot be found in time, and the accelerant precipitates on a membrane member is hard to be removed, etc, and the scheme of the invention is to solve the series of problems above. The dilation method comprises the following main steps: isolating a microwave radiation airspace; expanding the size of the reactor; using an external multi-stage cascaded filter to intercept the accelerant particles stage by stage; using low-frequency ultrasonic wave from the bottom of the reactor to strongly scatter the accelerant agglomerates in root position and simultaneously cleaning a quartz tube; using an ozone sensor to sense the reaction progress, and immediately turning off the relevant power supply before reaching the degradation endpoint; initiatively detecting the main inducement parameters of accelerant agglomeration, and giving an alarm when the acceleration agglomeration is over the time limit; and using high-frequency ultrasonic wave to help the membrane member of the filter to perform backwash cleaning operation.

Description

technical field [0001] The invention relates to a method for expanding the capacity of a photocatalytic wastewater degradation reactor combined with high-frequency ultrasonic anti-adhesion, 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 ...

AI Technical Summary

Problems solved by technology

[0044] 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.
