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.

Abstract

The invention relates to a high-capacity photocatalytic wastewater degradation device for precisely recycling titanium dioxide catalyst particles, belonging to the technical field of wastewater treatment. The following problems exist in the prior related art: the microwave energy is wasted, the single-tank wastewater treatment capacity is smaller, the internal high cyclic strength is insufficient, the bubble rising path is shorter, the oxygen supply concentration ratios in key areas are insufficient, the catalyst particle interception link is weaker, 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 at the problems. The structure of the device limits the microwave irradiation airspace, allows substantial capacity expansion of the reactor, is favorable for reinforcing supply of air atmosphere in the key degradation reaction areas, is suitable for finely intercepting the catalyst particles, can disperse the catalyst agglomerates in situ by strong force, simultaneously carries out ultrasonic cleaning on quartz tubes incidentally, can automatically and immediately turn off the related power supply at the degradation endpoint, and can warn the tendency of catalyst agglomeration.

Description

technical field [0001] The invention relates to a large-capacity photocatalytic waste water degradation device for strictly recovering titanium dioxide catalyst particles, 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 ...
