Phycomycetes microbial fuel cell and preparation method and application of phycomycetes microbial fuel cell

Abstract

The invention belongs to the technical field of biological fuel cells, and discloses a phycomycetes microbial fuel cell and a preparation method and application of the phycomycetes microbial fuel cell. The phycomycetes microbial fuel cell comprises an anode chamber, a cathode chamber, a transverse diaphragm, an anode, a cathode and an outer circuit, wherein phycomycetes, a culture solution and a carbon source are respectively installed in the anode chamber and the cathode chamber. In the operation process of the phycomycetes microbial fuel cell, operation is conducted by repeatedly converting the electrodes; in the whole operation process, with the help of synergistic effects of the phycomycetes, the effect that azo dye pollutants are degraded efficiently is achieved; the electrodes are alternately used for degrading the azo dye pollutants, therefore, the physiologically toxic effect on current-producing bacteria by the azo dye pollutants is eliminated, and continuous efficient current generation is realized; the phycomycetes is adopted as a biocatalyst for both the anode and the cathode, no metal catalyst is used for modification, no exogenous artificial mediator is added, aeration is not needed, therefore, the construction and operation cost of the microbial fuel cell is lowered, the sustainability of the microbial fuel cell is enhanced, and industrial amplified production of the microbial fuel cell can be conducted beneficially.

Description

technical field [0001] The invention belongs to the technical field of biological fuel cells, and in particular relates to an algal microbial fuel cell and its preparation method and application. Background technique [0002] Microbial Fuel Cell (Microbial Fuel Cell, referred to as microbial fuel cell) is a new bioelectrochemical device that uses microorganisms to convert organic matter into electrical energy. It is applied to the field of wastewater treatment and can use wastewater as fuel to degrade organic pollutants directly Generate electricity, so that waste water can be purified and recycled. [0003] The biodegradation of organic pollutants usually involves redox reactions, and the anaerobic bioanode and aerobic biocathode of microbial fuel cells can create conditions for the biodegradation of a variety of refractory organic pollutants. Studies have shown that microbial fuel cells can simultaneously enhance the degradation of various refractory organic compounds, su...
