Therefore, how to properly treat the oily wastewater becomes a problem to be solved urgently. At present, the oily wastewater mainly comprises the following treatment methods: gravity separation, centrifugal separation, flotation, coagulation, combustion, photocatalytic oxidation, adsorption, and the like. However, most of the methods have complex operation flow and complex process, and are easy to generate toxic substances to cause secondary pollution to the environment. Membrane separation methods which have been developed in recent years have been increasingly used for separation of oil-containing wastewater due to the characteristics of simple devices, wide application range, high separation efficiency and the like; wherein the key to the process is the performance of the superhydrophobic film.

The existing super-hydrophobic membrane has poor hydrophobicity and poor retention effect on salt ions in wastewater; therefore, how to prepare the super-hydrophobic membrane which has good hydrophobic property and good salt ion interception effect and is convenient for subsequent treatment and degradation is the research direction of the industry.
