Nitrification microbial fuel cell

The invention discloses a nitrification microbial fuel cell, which is composed of an anode chamber, a cathode chamber and a proton exchange membrane. The anode chamber is provided with a cubical reactor and a sealing cover. The lower part of the cubical reactor is provided with a water inlet pipe, the upper part is provided with a water outlet pipe, and the middle part is provided with an aeration zone, a reaction zone and an isolation board isolating the aeration zone from the reaction zone. The upper part of the cubical reactor is communicated with the lower part, and an electrogenesis matrix is filled into the cubical reactor. A nitrobacterium biofilm formation anode is placed in the electrogenesis matrix. An anode lead fixing pipe is disposed on the sealing cover at the top of the reaction zone. A gas distribution pipe is arranged at the bottom of the aeration zone. The cathode chamber is equipped with a cubical reactor and a sealing cover. The lower part of the cubical reactor is equipped with a water inlet pipe, and the upper part is equipped with a water outlet pipe. The cubical reactor is steeped with a cathode solution, in which a cathode is placed, and the top sealing cover is equipped with a cathode lead fixing pipe. With the inorganic matter ammonia as the raw material, the invention has the advantages of simple structure, mild operation condition, small internal resistance, good electrogenesis efficiency, high energy utilization rate, and simultaneous realization of wastewater nitrification and biological electrogenesis.
