The method mainly comprises the following steps: introducing one end of an optical fiber to the periphery of the quartz tube so that the tip of the optical fiber points to the inner cavity of the quartz tube; enabling the other end of the optical fiber to be close to and point to a detection window of an ultraviolet intensity detection instrument; continuously supplying air to the quartz tube cavity region with a minitype air pump to counteract air leakage due to various regions, and keeping the positive pressure state of the air in the region to prevent water invasion accidents; hermetically isolating a waveguide tube with a microwave-permeable material to prevent the ozone inversion cross flow; finely intercepting the catalyst particles with a plurality of cascade-connected negatively-charged filter membranes; and performing a plurality of steps for achieving the expansion goal of the device.

The invention relates to an expansion method of a reactor upgraded from a photocatalytic waste water degradation catalyst interception mechanism, and belongs to the technical field of waste water treatment. The method aims at solving a series of problems that a catalyst runs off, the single tank volume is small, a degradation reaction endpoint is difficult to distinguish, a catalyst aggregator cannot be dissipated forcefully in situ, catalyst aggregation cannot be perceived immediately, preventive measures on water burst of a quartz cavity are insufficient, etc. in the prior art. The method mainly comprises the steps of restraining microwaves to irradiate a designated area only, expanding a reactor dimension, improving air supply intensity for a key degradation reaction area, progressively intercepting the catalyst with an external cascaded three-stage back flushing filter, forcefully dissipating a catalyst aggregator in situ with ultrasonic waves from the bottom of the reactor, cleaning a quartz tube incidentally, monitoring a reaction course with an ozone sensor, automatically turning off a related power supply at the degradation endpoint, actively checking a catalyst aggregation trend, and the like.
