The invention relates to a novel air-supplementary stirring wheel. Centrifugal impellers are driven by a high-speed submersible motor, and a hollow strip-shaped stirring wheel is designed on the outersides of the centrifugal impellers. Under combined actions of water pressure and friction resistance of water intake pipes, the stirring wheel rotates at a low speed, liquid stirring is realized, andthe fresh air is exchanged when the liquid ejected from ejection holes on the upper wall face of the stirring wheel returns to a liquid pool through the air, so that functions of air supplement and stirring can be simultaneously realized.
