The pretreated sewage flows into an aeration chamber with a volute aerator 3 through a water inlet hole, the sewage is fully mixed with micro bubbles generated by the aerator through the aeration chamber in the rising process, and the aerator transfers the air on the water surface to the water through an air extraction pipeline. The aeration machine has the working principle that a vacuum area is formed in water by utilizing the high-speed rotation of an air dispersing impeller at the bottom of an air conveying pipeline, air on a liquid surface is input into the water through the aeration machine to fill vacuum, micro bubbles are generated along with the air and spirally rise to the water surface, and oxygen in the air is dissolved into the water along with the micro bubbles.
Due to the density imbalance between the gas-water mixture and the liquid, a vertical upward buoyancy is created, bringing the grease, jelly and suspended solids to the surface. During the floating process, micro bubbles can be attached to grease, jelly and solid suspended matters, and the grease, the jelly and the solid suspended matters are supported and maintained on the water surface by the bubbles after reaching the water surface. The sludge scraper runs along the entire liquid surface and pushes the grease, jelly and suspended solids from the inlet end of the air flotation tank 5 into the sludge discharge pipe at the outlet end. A horizontal screw conveyor 6 is arranged in the sludge discharge pipeline and used for conveying the collected sludge into a sludge collection pool. The purified sewage flows into the overflow groove and then automatically flows to the biochemical treatment part.
An open return assembly 4 extends from the aeration zone along the bottom of the air flotation tank 5. When micro bubbles are generated, the cavitation aerator 3 can form a negative pressure area at the bottom of the tank with the return pipe, and the negative pressure can lead the wastewater to return to the aeration area from the bottom of the tank and then return to the air floatation section. This process ensures that about 40% of the wastewater returns and the flotation stage can still operate without water.

The pretreated sewage flows into the aeration chamber with the volute aerator 3 through the water inlet hole, the sewage is fully mixed with micro bubbles generated by the aerator through the aeration chamber in the ascending process, and the aerator transfers the air on the water surface to the water through the air exhaust pipeline. The aeration machine has the working principle that a vacuum area is formed in water by utilizing the high-speed rotation of an air dispersing impeller at the bottom of an air conveying pipeline, air on the liquid surface is input into the water through the aeration machine to fill the vacuum, micro bubbles are generated along with the air and spirally rise to the water surface, and oxygen in the air is dissolved into the water along with the micro bubbles.
Due to the density imbalance between the gas-water mixture and the liquid, a vertically upward buoyancy is created, bringing the grease, jelly and suspended solids to the surface. During the floating process, micro bubbles can be attached to grease, jelly and solid suspended matters, and the grease, the jelly and the solid suspended matters are supported and maintained on the water surface by the bubbles after reaching the water surface. The sludge scraper runs along the entire liquid surface and pushes the grease, jelly and suspended solids from the inlet end of the air flotation tank 5 into the sludge discharge pipe at the outlet end. A horizontal screw conveyor 6 is arranged in the sludge discharge pipeline and used for conveying the collected sludge into a sludge collection pool. The purified sewage flows into the overflow groove and then automatically flows to the biochemical treatment part.
An open return assembly 4 extends from the aeration zone along the bottom of the air flotation tank 5. When micro bubbles are generated, the cavitation aerator 3 can form a negative pressure area at the bottom of the tank with the return pipe, and the negative pressure can lead the wastewater to return to the aeration area from the bottom of the tank and then return to the air floatation section. This process ensures that about 40% of the wastewater returns and the flotation stage can still operate without water.
