Systems and Methods for Sustainable Wastewater and Biosolids Treatment

摘要

Methods of sustainable wastewater and biosolids treatment using a bioreactor including a microbial fuel cell are disclosed. In some embodiments, the methods include the following: enriching an anode of the microbial fuel cell in the bioreactor with a substantially soluble electron acceptor; growing the bacteria in the presence of the anode enriched with a substantially soluble electron acceptor; oxidizing a substrate using the bacteria to produce free electrons; channeling the free electrons away from a terminal electron acceptor and to the enriched anode, the enriched anode serving as an electron acceptor; and carrying the free electrons from the enriched anode to a cathode of the microbial fuel cell to generate electricity.
