The first motor 602 can drive the rotating rod 603 to rotate, and then drive the mounting frame 801 and the circular plate 4 to rotate, and then drive the two stirring plates 808 to rotate to stir and mix the sewage and the strong oxidant, so that the sewage, the strong oxidant and the catalyst can be fully mixed for oxidation reaction. During the reaction, the external air can be sucked into the long tube 904 through the suction pump 901 to provide oxygen to the sewage, and the pollutants in the wastewater are oxidized and decomposed by the strong oxidant. After the sewage is treated, the sewage can be discharged through the drain valve 2;

While flushing the residual stains on the inner wall of the tank body 1, the rotating rod 803 and the turntable 804 are driven by the second motor 802 to rotate, thereby driving the movement of the two first linkage columns 805 on the turntable 804. The movement of the first linkage column 805 can be used to push the linkage rod 809, the second linkage column 807 and the sliding block 806 to move, thereby adjusting the distance between the two stirring plates 808. The distance between the two stirring plates 808 can be enlarged, so that the two stirring plates 808 are respectively attached to the inner walls on both sides of the tank body 1, which is convenient for scraping the inner wall of the tank body 1. The residual stains on the inner wall of the tank body 1 can be quickly removed, and the scraping is cleaner, the decontamination speed is faster, the efficiency is higher, and the effect is better.
