Catalytic oxidation device for removing organic matters in wastewater

The utility model relates to the technical field of wastewater treatment, in particular to a catalytic oxidation device for removing organic matters in wastewater, which can be used for continuously mixing the wastewater and a catalytic oxidant, so that the organic matters in the wastewater can be effectively removed. The wastewater mixed with the catalytic oxidant is continuously introduced into the treatment box and reacts with the ultraviolet emission lamp to remove organic matters in the wastewater, so that the working efficiency of removing the organic matters from the wastewater is improved; comprising a treatment box, a plurality of sets of ultraviolet emitting lamps, a first water pump and a mixing device, the multiple sets of ultraviolet emitting lamps are installed in the treatment box, and the input end of the first water pump communicates with the mixing device; the mixing device comprises a mixing barrel, a storage barrel, four groups of supporting rods, a discharging bent pipe, a first rotating
