A preparation method for a novel composite anode based on nitrogen-doped charcoal of sludge and porous volcanic, and a microbial fuel cell, relating to the technical field of resource utilization of new materials, new energy and wastewater. Active sludge is prepared into porous nitrogen-doped charcoal by using a nitrogen high-temperature pyrolysis baking method; and then, surface minerals are removed by using an acidification method to improve the electrical conductivity of the charcoal; finally, surface charcoal loading is performed by taking volcanic granules as a carrier to prepare and form nitrogen-doped charcoal granules on a volcanic surface. The novel granules have high porosity, high electrical conductivity and large specific surface area, and fully meet the performance requirement of the anode material of the microbial fuel cell. The anode of the novel nitrogen-doped porous charcoal can increase the loading capacity of electricity-producing bacteria and microorganisms of the anode of the microbial fuel cell, and improve the conversion rate of biomass energy in wastewater; by virtue of low-resistance characteristics, the electron transfer efficiency is also improved, and finally, the power of the microbial fuel cell is enhanced, so that both wastewater treatment and recycling and efficient biological power generation are achieved.
