The present invention relates to an oil-water separation apparatus which permits oil-water separation of heavily polluted oil-water mixed liquids or mixed liquids of high viscosity oil and water, etc., to be efficiently made.
The present invention consists in an oil-water separation apparatus characterized in that in a top-opened separator tank (A) into which oil-water mixed liquid is fed from a source liquid tank (B) in which the oil-water mixed liquid of the source liquid, being the object of treatment, is contained, the inside-tank space (5) is disected into an oil-water separation (A1) space and a separated crater containing space (A2), a partition plate (3) is hung in the tank, forming under its bottom a communication route (2) for enabling circulation between these two spaces, and while an oil outlet (7) is opened through the part of the tank wall where the separated oil accumulates, a plural number of charged plates (8a,b) on which a voltage is applied are arranged, each two of them vis-à-vis, in the aforementioned oil-water separation space (A1), said source liquid to be fed through the aforementioned oil-water separation space (A1)on which the electric field acts.
