Wastewater-degradation microwave photocatalytic device beneficial to inhibiting energy unnecessary dissipation

Abstract

The invention relates to a wastewater-degradation microwave photocatalytic device beneficial to inhibiting energy unnecessary dissipation, belonging to the technical field of wastewater treatment. The invention aims to totally solve the problem of energy unnecessary dissipation since the wastewater body absorbs abundant microwave energy, and the problem of scaling on the outer side surface of the quartz tube for an electrodeless ultraviolet lamp shield in the existing microwave photocatalytic degradation technique of industrial wastewater containing organic pollutants. The electrodeless ultraviolet lamp is arranged in a metallic wire-cage-shaped transparent microwave restrictor, microwaves are introduced into the microwave restrictor, so that the microwave restrictor can inhibit the microwave from unnecessary dissipation. On the basis of the structure, the design volume of the reactor is allowed to be greatly expanded, thereby greatly enhancing the single-tank wastewater treatment capacity of the reactor; and an ultrasonic transducer is arranged on the inner side surface of the side wall of the microwave photocatalytic reactor, thereby instantly clearing the scales under the action of high-frequency ultrasonic by using the ultrasonic transmission of the liquid medium.
