Microwave synergistic photocatalytic wastewater degradation reactor with enhanced catalytic particle interception

Abstract

The invention relates to a reactor for reinforcement of catalyst particle interception and microwave synergistic photocatalytic wastewater degradation, belonging to the technical field of wastewater treatment. The following problems exist in the prior related art: the catalyst intercepting link is weaker, the single-tank treatment capacity of the reactor is smaller, the repetitive operation frequency is high, the internal cyclic strength of liquid is insufficient, ozone utilization is incomplete, the degradation reaction endpoint is difficult to distinguish, catalyst agglomerates can not be dispersed in situ by strong force, and occurrence of catalyst agglomeration can not be perceived immediately. The invention aims to solve the problems once. The structure of the reactor separates and limits the microwave irradiation area, guides the ozone bubble flow to key degradation reaction areas, finely intercepts the catalyst particles with an external cascaded filter, can disperse the catalyst agglomerates in situ by strong force, simultaneously carries out ultrasonic cleaning on quartz tubes incidentally, can automatically turn off the related power supply when the degradation reaction reaches the endpoint, and can actively detect the tendency of catalyst agglomeration and carry out automatic warning.

Description

technical field [0001] The invention relates to a microwave synergistic photocatalytic wastewater degradation reactor that strengthens the interception of catalyst particles, 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 b...

AI Technical Summary

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.
