An oxygen supply device for water that increases the dissolved oxygen of water in the environment including the sea, lakes, rivers, dams, moats, a tank that is placed in the water and discharges gas dissolved water, and suction A pump for injecting the water into the tank, and a gas sending means for sending the gas to at least one part of the front or rear stage of the pump or the tank, and the gas is mixed and dissolved in the water sucked by the pump An apparatus for supplying oxygen into water , wherein the gas-dissolved water is configured to be discharged into water. The apparatus for supplying oxygen to water according to claim 1, wherein water discharged from the pump is injected into a gas reservoir formed in the upper part of the tank.   The water level in the tank is measured by measuring the difference between the pressure in the gas reservoir in the tank and the water pressure outside the tank, and the water level in the tank is maintained at a predetermined height. Item 3. The oxygen supply device for water according to Item 1 or 2.   The oxygen supply apparatus for water according to any one of claims 1 to 3, wherein a water level in the tank is adjusted by adjusting a gas delivery amount from the gas delivery means.   5. The gas level in the tank is prevented from being lowered and the water level is adjusted by discharging the gas in the gas pool formed in the upper part of the tank to the outside of the tank. The oxygen supply apparatus to water in any one.   6. The apparatus for supplying oxygen into water according to claim 5, wherein the gas in the gas reservoir formed in the upper part of the tank is discharged onto the water through a conduit. A nozzle is provided at the tip when water is poured into the tank, and the water ejected from the nozzle is arranged so as to generate a vortex in the water in the tank. Equipment for supplying oxygen to water. When injecting water into the tank , a nozzle is provided at the tip, and this nozzle is disposed near the top of the tank so that water ejected from the nozzle collides with a baffle plate disposed in the tank. The oxygen supply device for water according to any one of claims 1 to 6.   The apparatus for supplying oxygen to water according to any one of claims 1 to 8, wherein the bottom surface of the tank is opened and water is discharged toward the bottom of the water.   The apparatus for supplying oxygen to water according to any one of claims 1 to 8, wherein water is discharged from a bottom surface of the tank in a horizontal direction.   A flow path extending means is provided in the tank to extend the flow path length until the water supplied to the tank reaches the discharge port, thereby improving the solubility of the gas in the injected water and from the water discharge port. The apparatus for supplying oxygen to water according to any one of claims 1 to 10, wherein outflow of dissolved gas is suppressed. The oxygen supply device for water according to any one of claims 1 to 11, further comprising a circulation line for injecting a gas in a gas reservoir in the upper part of the tank into at least one of a front stage and a rear stage of the pump . The suction port of the pump and the discharge port of the tank are arranged so that the difference between the density of water in the area sucked by the pump and the density of water in the area discharged from the tank is a depth within 10 kg / m ^3. The oxygen supply device for water according to any one of claims 1 to 12, wherein the oxygen supply device is installed.
