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.

Abstract

The invention relates to a photocatalysis wastewater degradation reactor expanding method for automatically checking aggregation main cause parameters and belongs to the technical field of wastewater treatment. The problems that the catalytic agent is eroded, the microwave energy is wasted, the single-tank wastewater treatment amount is small, the cyclic strength of the inner liquid is insufficient, the degradation terminal point is difficultly identified, a catalyst agglomeration cannot be powerfully dissipated in situ, the catalyst agglomeration cannot be timely observed and the like exist in the conventional related technologies. The method aims to solve the series of problems. The method comprises the following steps: drawing the microwave irradiation range through a metal cage, bunching the rising bubble flow through a horn-shaped member, expanding the size of the reactor, gradually intercepting catalyst particles by using an external cascade three-stage backwash filter; dissipating the catalyst agglomeration by using the ultrasonic in-situ power at the bottom of the reactor, and incidentally cleaning the quartz tube; sensing the reaction progress by using an ozone sensor, and automatically controlling the related power switch mechanism by using a sensing electric signal; and automatically checking aggregation main cause parameters, and automatically giving an alarm when the index exceeds the limit.

Description

technical field [0001] The invention relates to a method for expanding the capacity of a photocatalytic wastewater degradation reactor by self-checking the parameters of the main cause of reunion, 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 sh...
