Method and device for separating emulsified oil in water

The invention belongs to the field of water treatment, relates to a method and a device for separating emulsified oil in water, and provides a method for separating the emulsified oil in the water, which comprises the following steps: enabling mixed liquid to pass through loosely stacked or compacted mixed weaving type fiber balls, enabling water drops or oil drops in the mixed liquid to collide with fibers, and adhering to the surfaces of the fibers with different surface properties, and under the action of fluid drag force, the emulsion breaking and oil-water separation are realized and are gathered and grown on the surfaces of the fibers, and then water drops or oil drops fall off from the surfaces of the fibers and are layered under the action of gravity, so that the emulsified oil separation is realized. The invention further provides a device for separating emulsified oil in water. The device is suitable for removing free oil and emulsified oil in wastewater, is also suitable for removing free water and
