Embodiment 1
[0036] A new type of fuel cell, including cathode (20cm×20cm graphite), catholyte, anode (20cm×20cm graphite), anolyte, microbial fuel, cation exchange membrane, copper wire and resistance (1000 ohm), the cathode is connected through the wire , The anode and the resistor are connected in series to form a loop; the anolyte is: NH 4 Cl 1.3%, NaHCO 3 0.3%, KH 2 PO 4 0.2%, glucose 2%, the rest is water (weight fraction); the anolyte is fed with high-purity nitrogen to ensure that it is in an anaerobic state. The catholyte is: potassium ferricyanide solution (weight fraction) with a concentration of 8%;
[0037] The above-mentioned microbial fuel is prepared from the following raw material bacteria in the following weight percentages: Rhodopseudomonas palustris 25%, Pseudomonas aeruginosa 20%, Geobacter sulphur-reduced 20%, Bacillus licheniformis 15%, Bacillus cereus 15%, Sulfur propionate 5%. The microbial fuel is a mixed bacterial solution, and the inoculum is 5% of the anolyte. ...
Embodiment 2
[0039] The anolyte is industrial wastewater from a fertilizer plant in Linshu, and the rest is the same as above. The composition changes of anolyte and anolyte after 36 hours of power generation are shown in Table 1:
[0040] Table 1
[0041]
[0042] At the same time, the voltage across the detection resistor is 782mv; it can be seen that the microbial fuel of the present invention not only has good power generation performance, but also can treat high-concentration polluted wastewater, and can also be used as an effective sewage treatment agent.
