Wastewater photochemical degradation reactor capacity expanding method for simultaneously reinforcing internal cycle of liquid

Abstract

The invention relates to a wastewater photochemical degradation reactor capacity expanding method for simultaneously reinforcing the internal cycle of a liquid belongs to the technical field of wastewater treatment. A scheme in the invention aims to solve problems comprising unsatisfactory microwave energy utilization condition, small wastewater throughput of the single tank of a reactor, insufficient internal liquid cycle intensity and the like in the prior art. The scheme mainly comprises the following steps: wrapping an electrodeless ultraviolet lamp with a metal cage in a quartz tube, communicating a waveguide tube with the inner cavity of the metal cage, positioning the quartz tube in the reactor, and constructing a microwave weak-irradiation airspace or a microwave zero-irradiation airspace between the outer wall of the metal cage and the inner wall of the reactor; arranging a horn-shaped member used for guiding and reinforcing the liquid flow cycle by means of rising ozone-containing bubbles just under the quartz tube; and extending and expanding the size of the microwave weak-irradiation airspace or the microwave zero-irradiation airspace in the reactor in a three-dimensional direction.

Description

technical field [0001] The invention relates to a method for expanding the capacity of a wastewater photochemical degradation reactor piggybacking enhanced liquid internal circulation, 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 developed rapidly 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 protecte...
