Nitrification microbial fuel cell

Abstract

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.

Description

technical field [0001] The invention relates to a microbial fuel cell, in particular to a nitrifying microbial fuel cell. Background technique [0002] In the last century, fossil fuels supported the development of the global economy, but fossil fuels are not renewable and will be exhausted in the next 100 years or a little longer. In energy utilization, the work of "opening up sources of income and reducing expenditure" has been placed in front of people realistically. Microbial fuel cell (MFC) is a device that converts chemical energy directly into electrical energy using enzymes or microorganisms as catalysts. MFC technology has many advantages such as wide source of raw materials, transformation of substrate into electric energy, mild operating conditions, low operating cost, and no harmful gas generation. It is recognized as a green and renewable energy utilization technology with great development prospects. [0003] The biological reaction in which ammonia is oxidiz...
