NOVELTY - The application provides an oil-water separating device based on graphene sponge, relating to sewage treatment equipment technical field The shell body inner part comprises a shell body graphene-based sponge filler, graphene-based sponge filler is set in the chamber, and the chamber is divided into a water distribution area and a gas distribution area, the area of graphene-based sponge filler is a oil-water separation area; the water distribution area is provided with a water inlet and an oil outlet, the gas distribution area is provided with a water outlet and an air inlet. The device forms an oil-water separation area by using graphene-based sponge filler, the oily sewage of the water distribution area can be divided into water phase and oil phase in the oil-water separation area, the water phase is discharged through the water outlet of the gas distribution area, the oil phase is adsorbed by graphene-based sponge filler, when the adsorption is saturated, the compressed air is blown by the air inlet, the oil stain on the graphene-based sponge filler can be blown off, and discharged through the oil outlet, so that the graphene-based sponge filler can be regenerated and used, the oil removing efficiency is high and the cost is low.
