APPARATUS FOR SEPARATING OIL FROM WASTE WATER CONTAINING OIL EMULSION AND METHOD THEREFOR

摘要

An apparatus for separating oil from waste water containing oil emulsion includes a waste water reservoir for holding the waste water containing oil emulsion, waste water treating arrangement for treating the waste water supplied fron the waste water reservoir, oil float waiting reservoir, oil collecting reservoir, chemical reactor tank, and chemical tank. The oil float waiting reservoir is to hold the treated water delivered from the waste water treating arrangement for a given time so as to make the oil part in the treated water float separated from the water part falling down by the force of gravity to the bottom. The waste water treating arrangement includes a treatment tank for holding the waste water to treat, catalyst supply device for supplying a catalyst to the waste water in the treatment tank to enhance the electrical conductivity of the waste water, and circulation piping provided with a magnetofluiddynamic device and circulation pump to circulate the waste water with enhanced electrical conductivity in order to destroy the stability of the oil droplets dispersed in the waste water.
