Abstract

PURPOSE: To remove the oil and suspended solids contained in a hard separate state in water throughly through simple operation with excellent efficiency by coupling a fluidized bed type separating method and a fixed type separating method ingeniously.
CONSTITUTION: The water contg. oil components and suspended soilds that are not separated by the differences in specific gravity in a storage tank 5 for water to be treated and a preseparating tank 1 for the same is successively passed through fluidized bed type separating tanks 2 and 3. In the respective tanks, the water cont acts with the composite granular bodies of a lipophilic polymer and a nonlipophilic polymer, by which the contained oil components and suspended solids are adsorbed, flocculated, coarsened and stripped to float or settle, whereby they are removed from the upper or lower parts of the tanks. Further, the treated water out from the tanks 3 contains approximately ≤5ppm oil, but the water out from a fixed bed type separating tank 4 contains substantially zero ppm oil.
