Abstract

The application belongs to the technical field of microbial fuel cell, and particularly relates to a UASB-MFC coupling device with modified three-phase separator as an anode of a microbial fuel cell, which comprises a upflow anaerobic sludge blanket reactor with a three-phase separator, a microbial fuel cell anode, an air cathode and other key devices. The anode material is composed of a conductive polymer PANI coated three-phase separator, which can realize three-phase separation in the reactor, and simultaneously serves as the anode material of the microbial fuel cell (MFC), which is beneficial to the adhesion of microorganisms and electricity generation. The application utilizes the UASB reactor to realize sludge treatment, and simultaneously utilizes the microorganisms in the sludge and the modified three-phase separator as the anode material to generate electric energy, which greatly reduces the electrode cost of the MFC, expands the practical application, and improves the wastewater treatment efficiency and COD removal rate.
