NOVELTY - A microbiological fuel cell comprises an anode chamber, a cathode chamber, a proton film, an anode, a cathode, a silica gel gasket, a base plate, and a silica gel spacer; where both the anode chamber and the cathode chamber are end-sealing type cylindrical structures; the cylindrical parts are the reaction rooms; an electrode inserting hole is respectively arranged at the upper parts of cylinder for the anode chamber and the cathode chamber; the anode reaction chamber and the cathode reaction chamber are set with an anode and a cathode and tightly introduced from the electrode inserting hole.    USE - The microbiological fuel cell is useful for processing aniline wastewater (claimed).    ADVANTAGE - The microbiological fuel cell has simple method, low cost, easy execution, and obvious effect which can be applied under normal temperature. Moreover, the removing rate of the COD and the aniline is higher.    DETAILED DESCRIPTION - A microbiological fuel cell comprises an anode chamber, a cathode chamber, a proton film, an anode, a cathode, a silica gel gasket, a base plate, and a silica gel spacer; where both the anode chamber and the cathode chamber are end-sealing type cylindrical structures; the cylindrical parts are the reaction rooms; an electrode inserting hole is respectively arranged at the upper parts of the cylinder for the anode chamber and the cathode chamber; the anode reaction chamber and the cathode reaction chamber are respectively set with an anode and a cathode and tightly introduced from the electrode inserting hole through leads; the proton film presents square form which is clamped between the two silica gel spacers and fixed through the two silica gel spacers; the centers of the silica gel spacer and the gasket are set with a square hole where the side is less than that of the proton film, the gasket, and the silica gel spacer from the proton film assembly; the two silica gel spacers are respectively positioned among the proton film assembly, the anode chamber, and the cathode chamber, and fixedly connected with each other through a fastening bolt after being packaged; the anode is carbon cloth, carbon paper, glass carbon, foaming nickel, carbon fiber, carbon nanotube, hydrogen storage alloy, particle graphite, or graphite felt; the cathode is carbon cloth, carbon paper, or graphite; and 0.10-0.7 mg/cm2 of platinum (Pt) catalyst is plated on the surface of the cathode. An INDEPENDENT CLAIM is a method for adopting microbiological fuel cell to process aniline wastewater, comprising: (a) injecting amylaceum derivative organic wastewater into the microbiological fuel cell; where the reacting temperature is 30-40 degrees C; externally connected with a resistance of 1000 ohms, using anaerobic sludge to start the microbiological fuel cell; when the voltage of the battery is less than 50 mV, completely changing the amylaceum derivative organic wastewater in the anode chamber, waiting for the loading voltage to stabilize beyond the 400 mV; where the microbiological fuel cell is successfully started; (b) converting the amylaceum wastewater in the anode chamber to be the mixed solution of the amylaceum and aniline after the microbiological fuel cell is successfully started, detecting the degradation rate of chemical oxygen demand (COD) in the anode chamber and the aniline and the electricity generating performance of the battery; and (c) reducing the content of the amylaceum in the anode chamber, and taking the aniline as a single electronic supplier.    DESCRIPTION OF DRAWING(S) - The drawing shows a sectional view of the microbiological fuel cell.
