Modified ceramic separation membrane and preparation method thereof
The invention discloses a modified ceramic separation membrane which comprises a ceramic separation membrane and a graphene layer directly growing on the surface of the ceramic separation membrane. According to the modified ceramic separation membrane, the graphene layer directly grows on the surface of the ceramic separation membrane, through modification of the graphene layer, the ceramic separation membrane has good hydrophobic performance, meanwhile, the graphene layer has a unique porous structure, grease compounds can effectively pass through the graphene layer, the average pore size of the ceramic separation membrane is reduced, and the oil-water separation efficiency is improved. The retention rate of ions and macromolecular substances is increased, the oil-water separation performance of the substances is achieved, and the method can be applied to treatment of oily wastewater, recovery of high-value oil and water and the like.
本发明公开一种改性陶瓷分离膜，包括陶瓷分离膜和直接生长在所述陶瓷分离膜表面的石墨烯层。本发明的改性陶瓷分离膜，在陶瓷分离膜表面直接生长石墨烯层，经过石墨烯层的改性，陶瓷分离膜具有良好的疏水性能，同时石墨烯层具有独特的孔状结构，有利于油脂类化合物的有效通过，降低陶瓷分离膜的平均孔径，提升离子以及大分子物质的截留率，实现物质的油水分离性能，可以应用于含油废水的处理以及高价值油水的回收等。
