The invention relates to a method for expanding a photochemical catalysis wastewater degradation reactor with an automatic endpoint shutdown function, and belongs to the technical field of wastewater treatment. The scheme is used for solving a series of problems of weak catalyst retaining link, unideal microwave energy utilization condition, small wastewater treatment capacity of a reactor single tank, insufficient large circulation strength of the internal liquid, difficult degradation endpoint time distinguishment, in-situ strong dispersing incapability of a catalyst agglomeration material and the like in the related prior art. The scheme mainly comprises the following steps of: utilizing a metal cage to narrow a microwave irradiation scope; adopting a trumpet-shaped member to bunch the rising bubble flow; expanding the size of the reactor; utilizing an external cascaded three-level flushing type filter to block the catalyst particles level by level; using ultrasonic waves from the bottom of the reactor to strongly disperse the catalyst agglomeration material in situ, and cleaning a quartz tube; and adopting an ozone sensor to monitor a reaction process, and utilizing sensing electric signals to automatically control a related power switch mechanism.

The invention relates to a capacity expansion method for a microwave photocatalytic wastewater degradation device capable of automatically monitoring and warning a terminal, and belongs to the technical field of wastewater treatment. The problems of loss of a nanometer catalyst, small wastewater treatment quantity of a single tank of a reactor, high frequency of repeated operation, difficulty in distinguishing a terminal moment of degradation reaction and incapability of in situ forced dissipation of catalyst clusters exist in the prior art, and the invention aims at solving the series of problems in the prior art completely. The capacity expansion method comprises the main steps of: separating a microwave irradiation airspace; significantly extending and expanding the size of the reactor; bunching and guiding bubble flow to release the bubble flow towards a key degradation reaction area in a concentrated way; intercepting particles of a nano photocatalyst stage by stage by using an external cascade three-stage reverse-washing filter; carrying out in situ forced dissipation on the catalyst clusters by using ultrasonic waves released from the bottom of the reactor, and simultaneously cleaning a quartz tube incidentally; and sensing a degradation terminal by using an ozone sensor, and driving a power control mechanism to automatically turn off a related power supply when being positioned at the terminal.
