Capacity expansion method of photocatalytic wastewater degradation reactor with the help of high frequency ultrasonic anti-adherence

Abstract

The invention relates to a dilation method of an anti-adhesion photo-catalytic wastewater degradation reactor with help of high-frequency ultrasound and belongs to the technical field of wastewater treatment. The relevant prior art has the problems that the accelerant interception link is weak, the treatment capacity of each tank of the reactor is low, the endpoint time of degradation reaction is hard to distinguish, the accelerant agglomerates cannot be strongly scattered in root position and the accelerant agglomeration cannot be found in time, and the precipitates on the membrane member are hard to be removed, etc, and the scheme of the invention is for solving the series of problems above. The dilation method comprises the following main steps: limiting a microwave radiation region; using a multi-stage cascaded filter to intercept the accelerant stage by stage; using low-frequency ultrasonic wave from the bottom of the reactor to scatter the accelerant agglomerates in root position and simultaneously cleaning a quartz tube; using an ozone sensor to monitor the reaction progress; automatically turning off the relevant power supply before reaching the degradation endpoint; initiatively warning the agglomeration tendency of the accelerant; 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 with the aid of high-frequency ultrasonic anti-adherence, and belongs to the technical field of CO2F wastewater treatment. Background technique [0002] Microwave photocatalytic degradation treatment technology, as an effective and 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, please refer to the Chinese patent application with publication number CN102260003A. [0004] The Chinese patent application with publication number CN102260003A uses microwaves as an excitation source to excite an electrodeless ultraviolet lamp to emit ultraviolet rays, and irradiates a suspension mixed with photocatalyst titanium dioxide inside the liquid, and the electrodeless ultraviolet lamp is...

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.
