PURPOSE: An apparatus for supplying oxygen into a water tank is provided to increase the dissolving effect of the oxygen, to minimize the consumption of the oxygen, and to reduce the cost of installation thereof. CONSTITUTION: The apparatus for supplying oxygen into a water tank(100) is comprised of a water circulation pump(2), an oxygen mixing device(4), a cylindrical oxygen dissolving vessel(13), an oxygen spraying device(12), a discharge pipe(9), and a decompression discharge plate(20a,20b,20c). The oxygen mixing device is a venturi tube for forcibly sucking and dissolving the oxygen from an oxygen supply device(5). The oxygen spraying device is constituted by an injection nozzle(11) of a multi-layer structure radially arranged in the oxygen dissolving vessel. The discharge pipe has a confluence injection tube installed under the oxygen spraying device. The decompression plate is drilled with a fine discharge opening(19a,19b,19c) on the front surface.
