PURPOSE:To maintain an excellent water purifying capacity over a long period of time and to effectively remove green algae, etc., by pressurizing and blowing a air- water mixture formed by mixing fine bubbles with water to a water purifying area and successively passing a far IR radiation area and microorganism water purifying area. CONSTITUTION:Water is sucked through a suction pipe 6 from a net cylinder screen 7 and is discharged from a discharge pipe 8 in the tangent direction within a mixing chamber 15 when the water purifying device is installed on the bottom of a pond a submersible pump 5 is driven and compressed to an air-water mixer 9 via an air supply hose. The fine bubbles are incorporated into the discharge water from the air-water mixer 9 at the time of discharge and the air-water mixture is made into swirling flow in the air-water mixing chamber 15, by which the sand, etc., in the sea water are centrifugally separated. The air-water mixture is then made into rising flow and is successively passed through a far IR septic tank 17 and a microorganism treatment tank 19, by which the air-water mixture is subjected to treatments, such as sterilization treatment and decomposition of org. solids. The air-water mixture is then released upward. The such operations are successively executed, by which the water in the pond is subjected to a circulation treatment. |
