Abstract

The invention relates to a microwave synergistic photocatalytic wastewater degradation reactor taking the electrostatic repulsion effect into consideration, and belongs to the technical field of wastewater treatment. The scheme aims to solve the series of problems that the accelerant intercepting link is weaker, the single tank handling capacity of the reactor is smaller, the repetitive operation is highly frequent, the finish point of the degradation reaction is hard to identify, the accelerant agglomerates cannot be powerfully eliminated in situ, the accelerant agglomeration cannot be immediately detected, the charge characteristics of the accelerant particles are not better used and the like in one package. According to the scheme, the structure is blocked and the microwave irradiation area is limited. In the structure, ozone containing bubbles are guided to key degradation reaction areas. Accelerant interception is strengthened by an electronegative hollow fibrous membrane by means of Coulomb repulsion. The accelerant agglomerates can be eliminated in situ in the structure, and an ultrasonic cleaning quartz tube is carried at the same time. Associated power supplies can be automatically powered off when the degradation reaction reaches the finish point in the structure. Accelerant agglomeration trend can be automatically sensed by the structure, and the trend is automatically warned.

Description

technical field [0001] The invention relates to a microwave synergistic photocatalytic wastewater degradation reactor considering electrostatic repulsion, 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 by a quartz tube. , ...
