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.

The invention relates to a method for expanding a photocatalysis wastewater degradation reactor for perfecting catalytic agent intercept and belongs to the technical field of wastewater treatment. The problems that the microwave energy is wasted, the single-tank wastewater treatment amount is small, the oxygen concentration degree is insufficient in a key area, the catalytic agent is eroded, the degradation terminal point is difficultly identified, a catalyst agglomeration cannot be powerfully dissipated in situ, the catalyst agglomeration cannot be timely observed and the like exist in the conventional related technologies. The method aims to solve the series of problems. The method comprises the following steps: isolating the microwave irradiation air space, expanding the size of the reactor, guiding the bubble flow to release to a key area at high strength, gradually intercepting catalyst particles by using an external cascade three-stage backwash filter; dissipating the catalyst agglomeration by using the ultrasonic in-situ power at the bottom of the reactor, and incidentally cleaning the quartz tube; sensing the reaction progress by using an ozone sensor, and immediately closing the related power supply when degradation end point is reached; actively sensing the main cause parameter of the catalyst agglomeration, and automatically giving an alarm when the limit is exceeded, and the like.

The present invention relates to a large capacity microwave photocatalytic wastewater degradation device of a self-inspection electrodeless UV lamp state, belonging to the technical field of wastewater treatment. In the related art, the problems include difficulty in real-time awareness of the functional state of an electrodeless lamp, water burst of a quartz pipe cavity of the electrodeless lamp, waste of microwave energy, smaller single-tank wastewater treatment capacity, difficulty in distinguishing the time of degradation reaction endpoint, magnetron corrosion caused by reverse crossflow of secondary ozone and the like, and the scheme is designed against the series of the problems. According to the scheme, one ends of optical fibers are introduced to rim of a quartz pipe and the ends point at the quartz pipe cavity, and the other ends of the optical fibers get close to and point at a detection window of a UV intensity detector. The UV lamp intensity detector can be further coupled with a UV intensity attenuation alarm and other extension mechanism. The electrodeless lamp and the functional state thereof are monitored in a real-time manner by the structure to prevent related faults, and the other problems are also solved by the structure.
