Method for coupling of PVDF/carbon fiber-based MFe2O4 photocatalysis conductive filtering membrane and MBR/MFC

The invention belongs to the fields of new energy and environment pollution control and discloses a method for coupling of a PVDF/carbon fiber-based MFe2O4 photocatalysis conductive filtering membrane and MBR/MFC. The membrane is used as the cathode of a microbial fuel cell (MFC), pollutant removal efficiency is improved through the cathode and photocatalysis under the powder generation driving of a biological anode, and finally membrane filtration is conducted to discharge water to achieve energy-efficient treatment of wastewater. A method for preparing the PVDF/carbon fiber-based MFe2O4 photocatalysis conductive filtering membrane comprises the steps of adding carbon nano powder and MFe2O4 photocatalyst to PVDF casting membrane solution in sequence, coating the surface of a carbon fiber cloth with the mixture by a certain thickness, and preparing the PVDF/carbon fiber-based MFe2O4 photocatalysis conductive filtering membrane with the phase inversion method. In an H type MFC, by placing the membrane on the cathode of the cell, energy-efficient treatment of wastewater can be achieved through biological power generation, photocatalysis and membrane filtration.
