Photocatalytic Wastewater Degradation Reactor Capacity Expansion Method Capable of Self-testing the Main Inducing Parameters of Agglomeration

Abstract

The invention relates to a photocatalysis wastewater degradation reactor expansion method capable of realizing self testing of agglomeration main incentive parameters, 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, insufficient concentration of oxygen supply of key areas, catalyst loss, difficult identification of degradation end points, unavailable in-situ powerful dissipation of catalyst agglomerates, and have the problems that the catalyst agglomeration can not be noticed in time and the like; and the method aims at solving the problems. The method mainly comprises the following steps of: partitioning a microwave irradiation airspace; expanding the reactor size; leading the bubble flow for high-intensity release toward a key area; gradually intercepting the catalyst particles by an external cascade three-level back flushing filter; powerfully dissipating the catalyst agglomerates in situ by use of ultrasonic waves from the bottom of the reactor while cleaning a quartz tube; sensing the reaction process by an ozone sensor, and cutting off the related power supply when the reaction reaches the degradation end point; and actively detecting the main incentive parameters of catalyst agglomeration, and automatically giving an alarm when the parameters exceed the standards.

Description

technical field [0001] The invention relates to a method for expanding the capacity of a photocatalytic wastewater degradation reactor capable of self-testing the parameters of the main cause of 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 ultraviol...

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.
