The invention relates to a method for enhancing the electrogenesis effect of a microbial fuel cell taking sludge as fuel, belonging to the technical field of environmental protection. The method comprises the following steps of: (1) fermenting excess sludge and primary sludge which are generated at a sewage treatment plant or a mixture of the excess sludge and the primary sludge under the condition of alkaline pH value of 9-10 for 6-8 days; (2) centrifugalizing a sludge fermentation mixture under the condition of 6,000 revolutions / minute for 10 minutes so as to obtain a sludge fermentation supernate; and (3) adding the sludge fermentation supernate to an air cathode single-chamber microbial fuel cell as a carbon source of a electrogenesis microbe for electrogenesis. The invention not onlyobviously enhances the electrogenesis effect of the microbial fuel cell taking the sludge as the fuel and realizes the high-efficiency resource utilization of the sludge, but also reduces the volume of the sludge and the pollution caused by the sludge on environment.
