Method for improving comprehensive performance of intermittent microwave photo-catalytic waste water degradation device

Abstract

The invention relates to a method for improving the comprehensive performance of an intermittent microwave photo-catalytic waste water degradation device, belonging to the technical field of waste water treatment. The invention aims to totally solve the problems that the microwave energy utilization condition is unsatisfactory, the single-tank waste water treatment amount of the device is low, scales are easily deposited on a quartz tube for the screening and protection of an electrodeless ultraviolet lamp and the outer side thereof, etc. in the existing microwave photo-catalytic waste water degradation technology. The method provided by the invention comprises the following steps: containing the electrodeless ultraviolet lamp in a cage-shaped microwave restraint made of a metal material; communicating a waveguide tube with the inner cavity of the microwave restraint; mounting an ultrasonic wave transducer in a microwave photo-catalytic reactor or on the outer surface of the microwave photo-catalytic reactor; and turning on a related power supply of the ultrasonic wave transducer. The method is beneficial to repress the vain dissipation of microwave energy, realizes the instant removal of deposited scales by means of high-frequency ultrasonic waves, and is beneficial to greatly improve the comprehensive performance of the microwave photo-catalytic degradation device.

Description

technical field [0001] The invention relates to a method for improving the comprehensive performance of an intermittent microwave photocatalytic wastewater degradation device, belonging 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 protected by a quar...
