By adjusting to 7 to 5 K9/cj, fine bubbles that require about 2 to 3 minutes to float W 1 m underwater can be obtained. Water containing such bubbles is injected from the discharge holes 15a to 15a of the discharge pipe 15 into the water W near the water bottom B, and a part of it hits the water bottom B, activating the sludge on the water bottom B, and at the same time, the water is injected. Thereafter, the water in the water W from the bottom B to the surface is activated by the bubbles that gradually rise in the water W.
