In order to solve the problem of oxygenation of bottom water, the inflatable aerator is used for pumping air into the water bottom and then releasing the air through the sand table air holes or the small holes of the nano air pipes to perform oxygenation, and because the pressure of the water bottom is large, bubbles can be pumped out from the water bottom to perform oxygenation only by using special high-power high-pressure aerator driving such as Roots fans and the like, and much power consumption is high in overcoming the water pressure, so that the power consumption is high, and the bubbles can drive toxic and harmful bottom water to rise to be mixed with the water above, so that toxic and harmful gases are diffused to the whole water body, and the phenomenon that the fish is dead faster when the aerator is opened in a fish pond is seriously threatening the cultivation safety.
