The method adopting the scheme mainly comprises the following steps of: partitioning a microwave radiation airspace; greatly extending and expanding the size of the reactor; beaming a bubble flow to enable the bubble flow to release to a focus degradation reaction area in a centralized manner; using an external cascaded filter to finely intercept catalyst micro-particles; using ultrasonic waves emitted from a depression at the bottom of the reactor to perform in-situ strong dissipation on the catalyst aggregate, and simultaneously cleaning a quartz tube; using an ozone sensor to sense a degradation endpoint, and automatically closing a related power supply at the endpoint; automatically detecting main incentive parameters of catalyst aggregation; and the like.

The invention relates to a waste water light degradation reactor expansion method for preventing ozone from flowing into a magnetron, belonging to the technical field of waste water treatment. Problems such as weaker catalyst interception link, lower single-tank treatment capacity of a reactor, difficulty in distinguishing a degradation reaction endpoint moment, incapability of powerfully dissipating catalyst clusters in situ and detecting catalyst agglomeration in time and magnetron corrosion caused by reverse crossflow of secondary ozone exist in the traditional relevant technologies, and the scheme aims to solve the series of problems. The waste water light degradation reactor expansion method mainly comprises the following steps of: limiting a microwave irradiation region; intercepting a catalyst stage by stage by using a multi-stage cascade filter; dissipating the catalyst clusters in situ by using low-frequency ultrasonic waves from the bottom of the reactor, and meanwhile, cleaning a quartz tube; perceiving the reaction progress by using an ozone sensor, and automatically turning off relevant power sources when a degradation end point is reached; actively warning the catalyst agglomeration trend; and separating a waveguide tube by using a wave-transparent airtight partition plate to block a reverse crossflow channel of gas containing ozone on the premise that the microwave transparence is not interfered basically.
