Abstract

The invention relates to a high-volume wastewater degradation reactor for automatically detecting the main incentive parameter of photocatalyst agglomeration, which belongs to the technical field of wastewater treatment, and aims at solving the problems of nano-photocatalyst loss, microwave energy waste, small single-tank wastewater treatment capacity of the reactor, insufficient high-circulation strength of internal liquid, hard discrimination at the final moment of a degradation reaction, unavailable in-situ powerful dissipation of photocatalyst agglomeration, unavailable immediate awareness in photocatalyst agglomeration occurrence and the like in current related background technology.

Description

technical field [0001] The invention relates to a large-capacity wastewater degradation reactor for automatic detection of the main inducement parameters of photocatalyst agglomeration, 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 ...

AI Technical Summary

Problems solved by technology

As mentioned earlier, when some pH values ​​are not pre-adjusted in place and the pH value is inappropriate, titanium dioxide particles are prone to agglomeration, which will affect its effective working interface area and affect its photocatalytic performance; especially for the CN102260003A proposal. Those relatively small particle size sections in the applicable catalyst particle size range are more prone to agglomeration problems caused by improper pH value pre-adjustment and inappropriate pH value; for this kind of catalyst particle agglomeration , it is necessary to take effective measures immediately to carry out the deagglomeration operation for the agglomerates; based on the structure of the CN102260003A scheme, the operator cannot immediately detect the agglomeration inside the reactor, and thus cannot make immediate disposal, thus , the limited efficiency of the reactor which can only be a small-scale structure due to many factors will be further reduced; therefore, in the application and operation of the reactor, especially, for example, in the possible large reactor or giant reaction In the application and operation of reactors, how to instantly perceive the main parameters that cause catalyst particles to agglomerate inside the reactor is a key issue. This is the eleventh issue.
