Abstract

The invention relates to a high-capacity intermittent industrial wastewater microwave photocatalytic degradation device, belonging to the technical field of wastewater treatment. The existing microwave photocatalytic degradation technology for the organic pollutant-containing industrial wastewater has the problems that microwave energy is wasted and practical single-jar wastewater treatment quantity is relatively small, and has the problem of scaling since an electrodeless ultraviolet lamp screen protector in the device is soaked in wastewater liquid by the outer side face of a quartz tube for a long term. The invention intends to solve the problems globally.In order to solve the problems, an electrodeless ultraviolet lamp is arranged in a silk screen cage-shaped nonopaque microwave restraining device made from metal material, the microwave is guided into the microwave restraining device to be restrained, the useless dissipation of the microwave can be stopped, and the designed volume of an expander can be allowed to be greatly enlarged on the basis of the structure, so that the single-jar wastewater treatment quantity of a reactor can be greatly improved. An ultrasonic transducer is attached to the outer side face of the side wall of the reactor, so that the scale can be timely removed after the high-frequency ultrasonic wave reaches up to the scale.

Description

technical field [0001] The invention relates to a large-capacity intermittent microwave photocatalytic degradation device for industrial wastewater, 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 quartz tube. , an air pump con...
