Abstract: The tip of a suction hose is supported by a floating support mechanism so that the suction port is maintained at a prescribed distance above the water surface and the base end of said suction hose is connected to the suction port of a turbofan. By the suction force of the turbofan, the oil film floating on the water surface is sucked along with the air above the water surface and the surface water through the suction hose from the suction port. The mixed fluid of air, oil and water that is delivered from the delivery port of the turbofan is sent to an oil-water separation device. The air is released into the atmosphere, and the oil and water are separated. For the turbofan, the rotational force of a separately disposed motor is transmitted by a belt transmission mechanism and rotates an impeller.
