GO-TiO_2/g-C_3N_4/PVDF复合膜对油田废水的处理
|
摘要
本文采用流延法制备了添加不同比例的GO-TiO_2以及g-C_3N_4的PVDF复合膜,并将改性后的PVDF膜应用于油田废水处理。通过对复合膜的表征以及对膜处理后的出水进行水质分析,从不同膜对油田废水的COD、SS以及含油率的去除率等方面测试膜的性能。结果表明:添加量GO-TiO_2后的PVDF膜综合性能更优异且处理含油废水的效果最佳。
In this paper,the PVDF composite membranes with different proportions of GO-TiO_2 and g-C_3N_4 were prepared by tape casting method,and the modified PVDF membranes were applied to oilfield wastewater treatment. Through the characterization of composite membranes and water quality analysis of treated effluent,the performance of composite membranes was tested from COD,SS and oil content removal rate of oilfield wastewater by different membranes. The results showed that the PVDF membrane with GO-titanium dioxide had excellent comprehensive performance and the best treatment effect for oily wastewater.
