The invention relates to a capacity expanding method for a photocatalysis waste-water degrading reactor capable of realizing UV radiator state self-inspection, and belongs to the technical field of waste water processing. In present correlated background technologies, there are the problems that: the function state of an electrodeless lamp is difficult to know timely; an electrodeless lamp placing chamber, that is a quartz tube chamber, has a water bursting problem; microwave energy is wasted; single pot waste-water processing capacity is smaller; catalysts loss; degradation terminal point is difficult to determine; secondary ozone flows crossly and corrodes magnetrons; and the like. The capacity expanding method aims at the problems. The capacity expanding method comprises the main steps: introducing one end of an optical fiber to the periphery of a quartz tube, making the tip of the optical fiber direct to inner cavity of the quartz tube, and making the other end of the optical fiber press close to and direct to the detection window of a ultraviolet light intensity detector. The capacity expanding method also comprises other multiple steps. The capacity expanding method of the invention helps to realize package solution on the series of the problems.

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.
