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.

Abstract

The invention relates to a blending weak-cavitation high-frequency ultrasonic anti-adhesion reactor for photocatalytic wastewater degradation, belonging to the technical field of wastewater treatment. The existing related technologies have the problems of microwave energy waste, small single-tank wastewater treatment capacity, weak catalyst particle interception link, difficult identification of the end point of degradation reaction and unavailable in-situ powerful dissipation of catalyst agglomerates, and have the problems that the catalyst agglomeration can not be noticed in time, the catalyst precipitate on a membrane component is not easy to clear and the like; and the reactor aims at solving the problems. In the reactor, microwaves are restrained by a metal cage, and the structure allows remarkable expansion of the reactor; the structure intercepts the catalyst particles by an external multi-level cascade filter; the structure dissipates the catalyst agglomerates by use of low-frequency ultrasonic waves while cleaning a quartz tube; the structure can automatically cut off the related power supply in time when the degradation reaction reaches the end point; the structure can detect the main incentive parameters of catalyst agglomeration; and the structure can assist the membrane component in a back flushing process by use of high-frequency ultrasonic waves.

Description

technical field [0001] The invention relates to a reactor for degrading photocatalytic waste water combined with weak cavitation and high-frequency ultrasonic anti-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 b...
