The invention relates to a large-scale photocatalytic
wastewater degradation reactor getting rid of trouble of catalyst agglomeration, and belongs to the technical field of
wastewater treatment. A conventional related technology has the problems that the catalyst is lost,
microwave energy is wasted, volume of a single tank is small, internal
liquid circulation intensity is not enough, utilization of
ozone is incomplete, an endpoint of a
degradation reaction is difficult to distinguish, aggregation materials of the catalyst can not be dissipated in-situ, and the like. Aiming at the above problems, the large-scale photocatalytic
wastewater degradation reactor getting rid of the trouble of the catalyst agglomeration is provided. A structure of the large-scale photocatalytic wastewater degradation reactor getting rid of the trouble of the catalyst agglomeration restricts
microwave irradiation airspace, guides
ozone air bubble stream to release toward a key reaction area, achieves step-by-step interception of catalyst particles by an external cascaded three-stage backflushing filter, can dissipate the aggregation materials of the catalyst in situ and clean a
quartz tube incidentally, and can automatically close relevant power supplies in time when the
degradation reaction reaches the endpoint, so that the energy waste can be prevented, and surplus and
pollution release of the
ozone can be completely eliminated.
