Abstract

The invention relates to a large-capacity wastewater degradation reactor capable of infusing charge characteristics of photocatalyst particles and belongs to the field of a wastewater treatment technology. The existing related background technique has the problems that a nano photocatalyst runs off, microwave energy is wasted, the single-pot wastewater treatment amount of a reactor is relatively small, a finishing moment of a degradation reaction is difficult to distinguish, a contact agent reunited object can not be forcedly dissipated in situ, the contact agent reunion can not be observed in time, the charge characteristics of contact agent particles can not be greatly utilized and the like, and the scheme aims to solve the problems. In the scheme, a metal cage can be used for restricting microwaves so as to greatly enlarge the reactor; the structure in the scheme strengthens inner liquid to be greatly circulated; the structure strengthens the interception of a contact agent by using a charge negative electricity hollow fiber membrane by Coulomb repulsion; 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 switch off a related power supply in time at a finishing point of degradation; and the structure can automatically detect main incentive parameters of the reunion of the contact agent.

Description

technical field [0001] The invention relates to a large-capacity wastewater degradation reactor in which the charging characteristics of photocatalyst particles are integrated, 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...
