[0002] Under the dual pressures of energy shortages and environmental pollution, microbial fuel cells (MFs) have attracted widespread attention due to their high efficiency, cleanliness, and adaptability, becoming a research hotspot in the energy field. As an emerging green energy technology, MFs utilize the metabolic activity of electrogenic microorganisms to convert chemical energy from organic waste into electricity, enabling simultaneous anaerobic activated sludge treatment and energy recovery. This approach holds significant promise for alleviating energy shortages and combating environmental pollution.

[0003] Exoelectrogenic bacteria are bacteria that can transfer electrons outside their cells. Extracellular exoelectrogenic bacteria are typically anaerobic or facultative anaerobes, capable of transferring electrons directly to chemical compounds or indirectly to electron acceptors. Exoelectrogenic bacteria can be introduced into anaerobic activated sludge using a microbial dosing device to cultivate them. However, when stored within a feed drum for dosing, the exoelectrogenic bacteria are exposed to air, shortening their shelf life and reducing their survival rate. Utility Model Content

[0021] Working principle: the power generation bacteria feeding device in use, first put the power generation bacteria into the raw material cylinder 1, then put the device into the anaerobic activated sludge to be treated, the device floats on the water surface by the floating ring 10, because the diameter of the floating ring 10 is greater than the diameter of the raw material cylinder 1, therefore, the device can keep stable on the water surface, by controlling the metering pump 4 to open, the metering pump 4 sends the power generation bacteria in the raw material cylinder 1 to the transfer cylinder 3, the power generation bacteria in the transfer cylinder 3 will contact the turbine 6, the turbine 6 rotates and drives the stirring rod 7 to rotate through the connecting shaft 5, the stirring rod 7 rotates to stir the power generation bacteria, and also can scrape the power generation bacteria adhering to the inner wall surface of the transfer cylinder 3, after the power generation bacteria enter the transfer cylinder 3, close the metering pump 4, then open the valve, the power generation bacteria in the transfer cylinder 3 will be discharged through the discharge pipe 8, the discharged power generation bacteria will enter the anaerobic activated sludge and mix with the anaerobic activated sludge, after discharging, the valve is closed.
