When the water volume inside the air flotation tank 1 is excessive, the floating ball 22 drives the connecting rod 16 and the top plate 32 to rise through buoyancy. When the top plate 32 touches the bottom end of the inductor 31, the sewage conveyance stops, thereby preventing sewage overflow caused by excessive sewage and polluting the nearby environment. When the height of the frame 15 needs to be adjusted, pads can be added to both sides at the bottom end of the frame 15. Start the second hydraulic cylinder 17. The second hydraulic cylinder 17 drives the separation tank 20 through the mounting plate 18, so that the separation tank 20 can be conveniently adjusted according to the height of the scraper 7. Adjusting the position of the separation tank 20 can facilitate sewage treatment even when the water volume is small.

The servo motor 9 drives the threaded rod 12 to rotate, thereby driving the first hydraulic cylinder 8 and the scraper 7 to move through the connecting sleeve 11 and the fixed plate 24, so that the scraper 7 scrapes the floating bubbles at the top inside the air flotation tank 1 into the inside of the separation tank 20. The first hydraulic cylinder 8 can drive the scraper 7 to lift and control the height of the scraper 7. The bubbles are scraped inside the separation tank 20, and then the defoaming agent is sprayed inside the separation tank 20 through the defoaming nozzle 13 to defoam.
