Room 4 keeps good oxidation-reduction potential, and cathode aerator 11 need to be disposed around cathode chamber 5, is carried out to 5 surrounding of cathode chamber
Noncontinuity is aerated, and the dissolved oxygen concentration around cathode chamber 5 is made to be maintained at 5~6mg/L.
Wherein anode chamber 4 and cathode chamber 5 is all made of the graphite felt of 10 × 10 × 5mm as electrode material, in order to effectively plus
The delivery rate of fast electronics, need to wrap up the stainless (steel) wire of one layer of 15 mesh as current-collector, two electrodes are by leading outside graphite felt
Line is attached, and adds the external resistance 7 of 500 Ω in external circuit, to accelerate the formation of biomembrane in system.
Wherein consider the precision too high or too low for temperature that can influence current monitoring device 6, the reading to producing electricity numerical value is produced
Raw error, need to be by current monitoring device 6 in closed thermostat 10, and temperature need to be maintained at 25 DEG C or so.
After the completion of whole system, microbiological fuel cell needs 5 days startup and stabilization time, Microbial fuel after stablizing
Battery can stablize electricity production, 2.31 ± 0.38uA of magnitude of current average out to that system is monitored.
Thus according to actual conditions, the organic loading range of waste water is can be predicted substantially in 300~1000mg/L, it is corresponding
Microbial fuel cell unit generate average current range in -0.44~2.69uA.
The above is only the preferred embodiment of the utility model, it should be pointed out that:For the common skill of the art
For art personnel, without departing from the principle of this utility model, several improvements and modifications can also be made, these improve and
Retouching also should be regarded as the scope of protection of the utility model.
