Abstract
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 into which oil-water mixed liquid is fed from a source liquid tank in which the oil-water mixed liquid of the source liquid, being the object of treatment, is contained, the inside-tank space is disected into an oil-water separation space and a separated water containing space, a partition plate is hung in the tank, forming under its bottom a communication route for enabling circulation between these two spaces, and while an oil outlet is opened through the part of the tank wall where the separated oil accumulates, a plural number of charged plates on which a voltage is applied are arranged, each two of them vis-a-vis, in the aforementioned oil-water separation space, said source liquid to be fed through the aforementioned oil-water separation space on which the electric filed acts.
