NOVELTY - The utility model claims an oil-water separation recycling device, comprising an oil absorbing component, a coating layer and a graphene modifying layer; the oil suction component can generate elastic deformation; the oil suction component is provided with a hole; the hole diameter of the hole is 1 m to 1000 m, the graphene modified layer is set on the inner wall of the hole; the coating layer covers the oil suction component; the coating layer is used for blocking the outside particulate matter entering into the hole of the oil suction component. when the oil-water separation recycling device is immersed in the water, the oil phase is liquid absorbed into the hole modified by the graphene modified layer, and the water phase liquid substantially not absorbed into it, which is very simple to realize the separation between the oil phase and liquid water phase liquid and at the same time, the porous oil absorbing component is pressed after being stressed, wherein the oil phase can liquid easily extruded, so as to realize the recovery of the oil phase liquid
