<p>PROBLEM TO BE SOLVED: To enhance efficiency of dissolving gas into liquid phase by providing a diffuser which mixes and stirs the gas collected by connecting the diffuser to a gas collector and a water stream from an underwater pump and discharges them into water at the tip of a branched pipe provided in the midway of a pipe, feeding the gas to the liquid phase together with an agitation water stream and performing agitation-aeration. SOLUTION: The underwater pump 1 having desired performance, provided under water, is connected to a gas feeding pipe 4 via water feeding pipes 2, 3 and the branched pipe 5. This gas feeding pipe 4 is immersed from above the surface of water into the water and also an umbrella type gas collector 6 is provided at the lower end part of the gas feeding pipe 4 and the gas collector 6 is connected to the diffuser 7 arranged at the tip of the branched pipe 5, and the gas collected with the gas collector 6 is mixed and stirred with the water stream from the underwater pump 1, and is discharged into water, and the gas is fed to the liquid phase together with the agitation water stream to perform agitation-aeration. Thus, the efficiency of dissolving gas into a liquid phase is enhanced.</p> |
