Photocatalytic Wastewater Degradation Reactor Capacity Expansion Method Incorporating Coulomb Repulsion

Abstract

The invention relates to a method for expanding the volume of a photocatalysis wastewater degradation reactor integrating a coulomb repulsion function, belonging to the technical field of wastewater treatment. An existing related technology has the problems that the microwave energy is wasted, the single-tank wastewater treating capacity is small, the oxygen supply concentration of a key area is insufficient, a catalyst flows away, the end time of degradation is difficult to distinguish, a catalyst agglomerate cannot be subjected to in situ strong dissipation, the agglomeration of the catalyst cannot be detected in time, the particulate charged characteristics of the catalyst are not put into good use, and the like. The method is provided for solving the series of problems, and mainly comprises the following steps of: obstructing a microwave radiation airspace; expanding the size of the reactor; guiding bubble flows to intensively release the bubble flows to an important area; enhancing catalyst interception by using a negatively charged hollow fiber membrane; carrying out in situ strong dissipation on the catalyst agglomerate by using ultrasonic waves emitted from the bottom of the reactor, and cleaning a quartz tube at the same time; sensing the reaction process by using an ozone sensor, and turning off a power supply immediately at the degradation end point; and automatically detecting main incentive parameters of the agglomeration of the catalyst.

Description

technical field [0001] The invention relates to a method for expanding the capacity of a photocatalytic wastewater degradation reactor in which Coulomb repulsion is integrated, 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 protected...
