PURPOSE:To surely carry out treatment by floating an oil suction device having plural suction nozzle parts freely liftably in the vertical direction and allowing the suction nozzle parts to communicate with the inside of an oil storage tank through a suction pipe. CONSTITUTION:Valves 4, 22 and 24 are closed, the switch of a control box 28 is turned on, a vacuum pump 2 is operated, and the air in the oil storage tank 1 is exhausted through the suction pipe 3, and the tank is depressurized. Consequently, a suction force is generated at the tip nozzle part 8a of a flexible small-diameter suction pipe 8. A soln. B contg. an oil component A such as defatted oil of emulsion type is supplied into a soln. tank 10 from the outside. The adsorption mat 15 of the oil suction device 12 floating on the liq. surface is impregnated with the oil component A. The oil component is then sucked by the tip nozzle part 8a of the suction pipe 8, discharged into the oil storage tank 1 from a small hole 9 and the lower opening of a pipe 5, and stored. Oil is excellently separated in this way. |
