Embodiment 1
[0037] Embodiment 1 uses the schematic diagram of the microbial fuel cell structure of cation exchange membrane to see appendix figure 1 .
[0038] The anion and anode chambers of the microbial fuel cell are separated by a cation exchange membrane of 8 cm x 8 cm. The cation exchange membrane can be a commercially available product. The cation exchange membrane of this embodiment was purchased from Zhejiang Qianqiu Industrial Co., Ltd. The anode chamber is sealed and the cathode chamber is open. The structure and connection method of the anode chamber, cathode chamber and external circuit can adopt the existing microbial fuel cell structure and connection method. In this embodiment, the anode is made of graphite felt, and the cathode is made of carbon cloth. Organic waste water (COD: 4850 mg / L) was added to the anode chamber as fuel, common anaerobic sludge was inoculated as electricity-producing microorganisms, and the battery was operated at room temperature for 19 days after...
Embodiment 2
[0040] Example 2 The schematic diagram of the microbial fuel cell structure using anion exchange membranes is shown in the appendix figure 1 .
[0041] The anion and anode compartments of the microbial fuel cell are separated by an anion exchange membrane of 8 cm × 8 cm, and the anion exchange membrane can be a commercially available product. The structure and connection method of the anode chamber, cathode chamber and external circuit can adopt the existing microbial fuel cell structure and connection method. In this embodiment, the anode is graphite felt and the cathode is carbon cloth. Organic wastewater (COD: 4850mg / L) was added to the anode chamber as fuel, common anaerobic sludge was inoculated as electricity-producing microorganisms, and the battery was operated at room temperature after an external resistance of 1000Ω.
[0042] This kind of MFC using anion exchange membrane, the output voltage will be stable at about 0.32V, see attached Figure 4 shown. The maximum po...
