The invention relates to a
photocatalysis wastewater degradation reactor expanding method for automatically checking aggregation main cause parameters and belongs to the technical field of
wastewater treatment. The problems that the catalytic agent is eroded, the
microwave energy is wasted, the single-tank
wastewater treatment amount is small, the
cyclic strength of the inner liquid is insufficient, 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: drawing the
microwave irradiation range through a
metal cage, bunching the rising bubble flow through a horn-shaped member, expanding the size of the reactor, 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 automatically controlling the related power switch mechanism by using a sensing
electric signal; and automatically checking aggregation main cause parameters, and automatically giving an alarm when the index exceeds the limit.
