NOVELTY - The oil-water mixed liquid separating method involves extending a first end of a conduit into an oil absorbing medium. The oil absorbing medium is placed in an oil-water mixed liquid to be process. The oil absorbing medium is formed as a graphene modified sponge with hydrophobic property. A second end of the conduit is connected with a suction device. The suction device is opened to extract oil phase liquid in the oil absorption medium through the conduit. The oil-water mixed liquid is separated from the oil-water mixed liquid by an external suction device. USE - Oil-water mixed liquid separating method. ADVANTAGE - Improve the oil-absorbing threshold value and uses the oil-absorbing medium material with large volume. Effectively save the use of the oil-absorbing medium material. Process is different from manual extrusion operation, realizes full automatic and high efficiency separating oil-water mixed liquid. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic diagram of an oil-water mixed liquid separation device.
