Reactor capacity expansion method for self-checking of the main cause of agglomeration parameters of wastewater photodegradation catalyst

The invention relates to a reactor capacity-expanding method with a self-inspection function for a main agglomeration inducement parameter of a wastewater photodegradation catalyst and belongs to the technical field of wastewater treatment. The reactor capacity-expanding method aims at solving the problems of catalyst loss, microwave energy waste, low single-tank capacity, incomplete ozone utilization, difficultly-distinguished degradation reaction endpoint time, incapacity of powerfully dissipating catalyst agglomerates in situ, incapacity of detecting the occurrence of catalyst agglomeration in time, and the like, existing in the existing related technologies. The method adopting the scheme comprises the mainly steps of: restraining a microwave to enable the microwave to only irradiate a specified area; expanding the dimensions of a reactor; increasing the intensity of air supply for a key degradation reaction area; intercepting the catalyst by an external cascaded three-stage backwash-type filter stage by stage; powerfully dissipating the catalyst agglomerates in site by an ultrasonic wave from the bottom of the reactor, and incidentally cleaning a quartz tube simultaneously; monitoring the reaction progress by an ozone sensor, and automatically turning off the related power supply while arriving at a degradation endpoint; and actively performing self-inspection on the tendency of catalyst agglomeration.
