Abstract:
1. A device for in-situ treatment of sediment simultaneous with microbial electricity generation, wherein the device is used as a microbial fuel cell placed in the sediment of a water body, the microbial fuel cell using organics in the sediment as fuels, the device comprises: a first insulated tube having at least one perforated section disposed between a closed end and an open end of the insulated tube, the open end allowing for air to flow therethrough, the at least one perforated section including more than two holes extending through the insulated tube; a membrane cathode being wrapped about the at least one perforated section to form a cathode chamber within the insulated tube, the membrane cathode being in contact with air located within the insulated tube via the more than two holes; an anode being wrapped about the membrane cathode such that an inner surface of the anode is adjacent to the membrane cathode and an outer surface of the anode is configured for contact within the sediment; and a second insulated tube having an open end and a cathode chamber formed therein and being interconnected to the first insulated tube via a connecting tube such that the cathode chamber of the first insulated tube is in fluid communication with the cathode chamber of the second insulated tube and such that the open ends of each of the first and second insulated tubes open in a direction away from the connecting tube.
