In recent, oily wastewater as a special contaminant has seriously impacted the ecological environment. In this work, nature and green materials are used to prepare the SA-PVDF membrane taking freezing and salt out super hydrophilic modifying. Therefore, obtained membrane exhibited good membrane flux, excellent recyclability, and superior separation efficiency. More importantly, obtained filter membrane was green, eco-friendly, and cost-affordable. Therefore, such a simple, universal, and facile method could be used in other organic and inorganic materials for preparing filter membranes, which plays a significant role in construing novel filtration membranes to remove oil from oily wastewater in practical life.
