Description

technical field [0001] The invention relates to the technical field of microbial batteries, in particular to a bioelectrochemical sewage treatment device and method for bacteria and algae. Background technique [0002] With the worldwide industrial development and population growth, the energy crisis is becoming more and more serious. Existing methods of power generation, such as coal-fired, hydraulic, wind, solar, and nuclear power generation, have disadvantages that are difficult to overcome, such as the reduction of mineral deposits, the continuity of electricity production, and the difficulty of collecting electricity. Currently, microbial fuel cells represent the latest way to generate electricity: the use of bacteria to oxidize organic matter to generate electricity. Its working principle is a bioelectrochemical device that directly converts the chemical energy of fuel into electrical energy by using the catalysis of microorganisms. The main uses of microbial fuel ce...
