Abstract

PURPOSE: To provide a treatment process in which oil and floating solid matters can be separated from emulsified oil containing waste water at a high rate in a short period of time with low installation and treatment costs and which permits long time continuous treatment.
CONSTITUTION: The emulsified oil containing waste water to be treated is supplied to a storage tank 1 where emulsion fracturing treatment is made with an emulsion fracturing agent added and a screw 2 operated. Next, treated water is fed to a gravity separating tower 4 by a pump 3 to undergo gravity separation treatment. Separated floating oil is discharged through a flotation separating layer 5 and a discharge port 6. Treated water is fed to a first coarse particle making element 8 having inside a fibrous layer 7 made of hydrophilic synthetic fiber, and the oil changed in coarse particles is discharged through the flotation-separated oil tank 10 of a first flotation separating tower 9 and through a discharge port 11. Thereafter, treated water is treated in a similar manner while flowing through a coarse particle making element 13 made almost similarly to said coarse particle making element 8 and through a flotation separating tower 14.
