The invention relates to a photocatalysis wastewater degradation reactor capacity expanding method capable of incidentally preventing lamp region from causing water burst, belonging to the technical field of wastewater treatment. Existing relevant technologies has the problem of the water burst of an electrodeless lamp installing cavity, namely, a quartz tube cavity, and also has the problems of microwave energy waste, slightly small single-tank wastewater treatment capacity, catalyst agent loss, difficulty in distinguishing degradation reaction endpoints, incapability of immediately finding catalytic agent agglomeration, corrosion of secondary ozone reverse channeling to a magnetron, and the like. Aiming at the series problems, the capacity expanding method mainly comprises the steps of: connecting a miniature diaphragm pump used for replenishing air at a normal state and with low power consumption and low flow to an air channel leading into the quartz tube cavity in a bypass manner; restraining a microwave irradiation airspace by using a metal cage so as to conveniently largely expand the capacity of a reactor; intercepting a catalytic agent by stages by using a multi-stage filter; sensing a degradation endpoint by using an ozone sensor, and automatically switching off a power supply at the degradation endpoint; self-detecting the agglomeration trend of the catalytic agent; separating a waveguide tube by using a wave-transparent airtight partitioning plate, and blocking a secondary ozone reverse channeling channel.
