Nondestructive, vibration wave membrane assistant and contact agent adhesion resistant photocatalytic wastewater degradation reactor

Abstract

The invention relates to a nondestructive, vibration wave membrane assistant and contact agent adhesion resistant photocatalytic wastewater degradation reactor, belonging to the technical field of wastewater treatment. The reactor is used for solving problems in the current related technology, such as contact agent loss, microwave energy waste, small single-tank volume, difficulty in distinguishing the degradation reaction end point moment, incapability of forcefully dissipating contact agent agglomerates in situ, incapability of detecting contact agent agglomeration in time and difficulty in clearing contact agent precipitates on a membrane assembly. The structure of the reactor in the scheme limits the microwave from irradiating the airspace to allow the large-scale volume expansion of the reactor; the structure intercepts contact agent particles through a plurality levels of cascaded external filters, dissipates the contact agent agglomerates through low-frequency ultrasonic waves and cleans a quartz tube at the same time; the structure can automatically turn off a related power supply when the degradation reaction reaches the end point so as to avoid energy waste; the structure can detect the main incentive parameters of contact agent agglomeration to actively send out an alarm in case of exceeding the standard; and the structure further assists the operation of a back wash program of the membrane assemblies of the filters through high-frequency ultrasonic waves.

Description

technical field [0001] The invention relates to a photocatalytic waste water degradation reactor with non-damaging vibration wave aiding film and anti-catalyst adhesion, and belongs to the technical field of CO2F waste water 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 ...

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.
