Abstract

High energy consumption, secondary pollution and frequent maintenance of equipment have greatly increased the cost of oil-water separation on ships, and the effective use of organic waste can solve similar problems well. The discarded tea leaves were ground into powder to make a solution, and the tea powder was uniformly coated on the PVDF (polyvinylidene difluoride) membrane by vacuum filtration, and a tea powder-PVDF filter membrane with super hydrophilic-underwater oleophobicity was prepared. Using this membrane for emulsified oil separation experiments, the results show that the initial efficiency of tea powder-PVDF filter membrane separation of emulsified oil-water mixture is 99.6%, and after ten repeated experiments, it still maintains a high separation efficiency of 96.1%. Since the membrane is prepared by using waste without chemical reagents and the process is not complicated, it is a simple, green and low-cost method for preparing oil-water separation materials.
