PROBLEM TO BE SOLVED: To efficiently treat water by mixing and reacting gas and liquid by providing an apparatus which is compact and which is easily managed and maintained. SOLUTION: The gas is mixed into the water to be treated by the ejector effect. The obtained mixture is jetted into a cylindrical pressure tank from the lower part of the tank in the tangential direction on the bottom surface so that the gas is dissolved into the water to be treated while the mixture is moving upward whirlingly from the lower part of the pressure tank. A cylindrical tank open to the atmosphere is arranged at the succeeding stage of the pressure tank, and the gas-dissolved water discharged from the upper part of the pressure tank is jetted from the lower part in the tangential direction on the bottom surface of the cylindrical tank open to the atmosphere in the cylindrical tank, so that the gas component dissolved in the water to be treated is made to be minute bubbles and the minute bubbles are made to float upward from the lower part in the tank open to the atmosphere.
