Microbial fuel cell with double chambers for simultaneous phosphorus and nitrogen removal

Abstract

The invention discloses a microbial fuel cell with double chambers for simultaneous phosphorus and nitrogen removal. The fuel cell comprises a reaction system and a data acquisition monitoring system. The reaction system comprises an anode reaction system and a cathode reaction system, wherein the anode reaction system comprises anode microorganisms, an anode electrode, an anode chamber, a sampling hole, a sample feeding hole and an electrolyte; the cathode reaction system comprises cathode microorganisms, a cathode electrode, a cathode chamber, a water feed pipe, a water outlet pipe, a constant flow pump hose, an air-blowing pump, a brown buffer bottle, an aeration head, a constant flow pump and an electrolyte. The anode electrode and the cathode electrode are tightly attached on the two sides of a proton exchange membrane. The data acquisition monitoring system comprises a static wire, a load, a lead, a data acquirer and a computer. The microbial fuel cell runs discontinuously, and is simple in structure, low in internal resistance and efficient and stable in performance; the microbial fuel cell has the effects in two aspects of capacity and water treatment, and therefore, a new method is developed for phosphorus and nitrogen removal by use of the microbial fuel cells.

Description

technical field [0001] The invention belongs to the technical field of biological fuel cells, in particular to a dual-chamber microbial fuel cell for synchronous denitrification and phosphorus removal. Background technique [0002] Eutrophication, also known as water bloom, refers to the phenomenon of water pollution caused by excessive plant nutrients such as nitrogen and phosphorus in lakes, rivers, reservoirs and other water bodies. Due to the enrichment of nitrogen and phosphorus nutrients in the water body, the rapid reproduction of algae and other plankton is caused, the dissolved oxygen content of the water body is reduced, and the pollution phenomenon of the decline or even extinction of algae, plankton, plants, aquatic organisms and fish is caused. The prevention and control of eutrophication is the most complicated and difficult problem in water pollution treatment. The usual secondary biochemical treatment method can only remove 30-50% of nitrogen and phosphorus. ...
