Abstract
The invention relates to a microwave photocatalytic wastewater degradation device allowing greatly expanding single pot treating capacity and belongs to the technical field of wastewater treatment. The existing microwave photocatalytic degradation technology aiming at industrial wastewater containing organic pollutants has the problems of microwave energy waste and small practical single pot wastewater treating capacity; in addition, in the prior art, the phenomenon of scale deposit can occur after the outer side surface of a quartz tube for shielding an electrodeless ultraviolet lamp is soaked in wastewater for a long time, a scale layer formed by the scale deposit blocks the permeability of light and also affects the wastewater treatment efficiency of the existing device; and the microwave photocatalytic wastewater degradation device aims at solving all the problems. The device adopts the structure that the electrodeless ultraviolet lamp is arranged in a wire mesh cage-shaped non-light tight microwave restraint made of metal material, and leads microwave into the restraint to restrain the microwave, so that microwave is free from inconducive dissipation, the design volume of a reactor is allowed to be greatly expanded based on the structure, and further the single pot wastewater treating capacity of the reactor is greatly enhanced. The device instantaneously eliminates the scale layer through high-frequency ultrasonic wave.
Description
technical field [0001] The invention relates to a microwave photocatalytic waste water degradation device that allows greatly expanding the treatment capacity of a single tank, and belongs to the technical field of CO2F waste water 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 ...
