Abstract:

The recovery process of crude oil or offshore oil leakage will produce a large amount of oily sewage,which brings great threat to the environment.Graphene and derived materials have large specific surface area,special pore structure and so on,which have attracted wide attention in the field of oil removal from oil-containing wastewater.The research progress of graphene-derived oil removal materials such as 3D graphene and graphene composite membrane in the treatment of oily waste was reviewed.The research on 3D graphene oil-absorbing materials was aimed to optimize the micropore structure,surface wettability,and improve the mechanical properties and service life.And the oil-water separation materials of graphene composite membrane mainly improved the flux,antifouling ability and stability of the membrane.At present,the synthesis process of graphene and derived oil removal materials was complicated and the stability was poor.In the future,the research on graphene and derived deoiling materials wouldl focus on reducing cost,improving stability and applicability.

Key words: oily sewage, three-dimensional graphene, graphene composite membrane
