Embodiment Construction

[0082] specific implementation plan

[0083] refer to Figure 1 to Figure 4 , the main appearance and structure of the microbial fuel cell using the water lettuce powder suspension as the anode substrate is as follows. The rubber cushion 5 of the membrane 4 (DuPont NR211 membrane) is fixed by 8 screws, nuts and screws 6 (3 on the left and right, and 2 on the bottom). 1, 2 The two pole chambers have the same structure and are axisymmetric. Each pole chamber has a small hole under the plexiglass wall on the other side of the proton membrane. Plastic conduit, clamped by water-stop clips to prevent leakage. There are three holes (2 large and 1 small) on the top of each pole chamber, and in the middle of each pole chamber is a large hole 8, which is inserted into the electrodes fixed with rubber plugs. The electrodes inserted into the cathode and anode chambers are made of a copper wire and The carbon paper is connected, and the copper wire and the carbon paper are clamped by be...

Abstract

The invention relates to the field of microbial fuel cells and discloses a microbial fuel cell with water hyacinth powder suspension liquid as an anode substrate. The microbial fuel cell is formed by splicing two half-opening boxes made of acrylic organic glass, two soft rubber pads clamping a proton exchange membrane are arranged in the middle of the microbial fuel cell and are fixed through nuts and screw slices, and the proton exchange membrane divides the cell into a cathode chamber and an anode chamber. The microbial fuel cell is combined with treatment of water hyacinth, energy released when microorganisms consume crushed water hyacinth is converted into electricity, main components of waste gas produced in the process comprise carbon dioxide and water, waste gas processing is not needed, secondary pollution is avoided, the microbial fuel cell is clean, environment-friendly and high in safety coefficient and can treat and make use of the water hyacinth while supplying electricity, accordingly the problem that a large amount of the water hyacinth is accumulated and cannot be efficiently used is solved, and a novel and reasonable utilization method is developed.

Description

technical field [0001] The invention relates to the field of microbial fuel cells, in particular to the use of water lettuce powder suspension as the anode substrate of the microbial cell. Background technique [0002] Microbial fuel cell (MFC for short) is a special fuel cell that uses microorganisms (Microbe) as a biocatalyst to directly convert the chemical energy of fuel into electrical energy. MFC can utilize different carbohydrates, and can also utilize various complex substances contained in wastewater. It can be a device that uses bacteria as a catalyst to oxidize organic or inorganic substances while generating an electric current. The electric energy generated by the interaction between the bacteria and the substrate is transferred to the anode (negative terminal) and then passes through the external circuit, passing through the conductive material with resistance or driving the load to work, and finally the current stays at the cathode (positive terminal). By co...
