Microbial fuel cell potting soil and method for in situ remediation of chromium contaminated

The present invention discloses a microbial fuel cell and a method of potting soil Cr for in situ remediation of contaminated, the microbial fuel cell plants, including pots and grown in a plant pot, the pot from the outer structure of the pelvic wall sequentially into a plastic film web, a graphite cathode layer, the glass fiber layer and a graphite anode layer; graphite cathode layer of the anode and the graphite layer is connected by a wire to the battery, the battery source is connected; filling said flowerpot a mixture of soil and activated sludge uncontaminated. The present invention is a cathodic reduction mechanism using a microbial fuel cell (MFC), in situ remediation of soil technology, and the organic MFC is a new technology energy into electrical energy, which can only MFC pot by cathodic reduction of hexavalent chromium can also generate electrical energy storage.
