Abstract

The invention relates to a large-capacity photocatalytic wastewater degradation device capable of greatly utilizing charge characteristics of a contact agent and belongs to the field of a wastewater treatment technology. The existing related technique has the problems that microwave energy is wasted, the single-pot wastewater treatment amount is relatively small, the oxygen supplying concentration ratio of an important region is not enough, an intercepting link of contact agent particles is relatively weak, a finishing moment of a degradation reaction is difficult to distinguish, a contact agent reunited object can not be forcedly dissipated in situ, contact agent reunion can not be observed in time, the charge characteristics of the contact agent particles can not be greatly utilized and the like, and the scheme aims to solve the problems. The structure limits microwave radiation airspace and can enable a reactor to be greatly enlarged; the structure is good for forcedly supplying an air atmosphere of an important degradation reaction region; in the structure, a charge negative electricity hollow fiber membrane is used for strengthening the interception of the contact agent; the structure can forcedly dissipate the contact agent reunited object in situ and incidentally cleans a quartz tube in an ultrasound manner; the structure can automatically close a related power supply in time at the finishing point of degradation; and the structure can alert the reunion tendency of the contact agent.

Description

technical field [0001] The invention relates to a large-capacity photocatalytic wastewater degradation device that makes good use of the charged properties of a catalyst, 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 attracted much attention 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 ...
