Abstract:
Provided are: a device for dissolving oxygen in water that can efficiently form bubbles in a liquid and can dissolve oxygen contained in these bubbles in a large volume of liquid in a short period of time while suppressing energy consumption; and a method for dissolving oxygen in water using the same. The device for dissolving oxygen in water is provided with: a box-shaped tank provided with a peripheral wall having a flow changing section that changes the direction of part of the flow of a first liquid, a base part that surrounds the peripheral wall, and drop holes provided on the base part; a first infusion pipe for infusing the first liquid into the box-shaped tank; a second infusion pipe for infusing a second liquid into the same; and a downward pipe linked to the drop holes. A first opening for the first infusion pipe opens above the inside of the flow changing section, and a second opening for the second infusion pipe opens above the drop holes.
