Device and Method for Improving Methane Production in Anaerobic Digestion Through Magnetic Field of Current-Carrying Coil

Abstract: a device for improving methane production in anaerobic digestion through a magnetic field of a current-carrying coil is provided, which relates to the field of microbial anaerobic digestion. the device includes a feed system, a digester, a stirring system, a magnetic field generation system, a magnetic field measurement system, and a gas flow measurement system. a method for improving methane production in anaerobic digestion through a magnetic field of a current-carrying coil is further provided, including the steps of collecting and pretreating digestion feedstock, collecting and pretreating anaerobic digestion inoculum, manufacturing a current-carrying coil-assisted anaerobic digestion system, starting an anaerobic digestion experiment, and confirming experiment results. a magnetic field is generated by evenly winding a current-carrying coil around a digester, which can provide faster electron transfer for methane anabolic reaction, promote methane anabolic process, and improve the methane yield and efficiency.
