Application method of single-chamber air cathode MFC

Abstract

The invention provides a single-chamber air cathode MFC which comprises a reactor, carbon paper of a PTFE diffusion layer and a voltage detection system. The reactor is divided into an anode chamber and a cathode chamber by the carbon paper of the PTFE diffusion layer; a carbon brush is used as the anode in the anode chamber, and air is used as the cathode in the cathode chamber; a Maker's duino core plate and an ADC chip are mounted on a breadboard; and the ADC chip is in communication connection with the Maker's duino core plate, the anode of the MFC device is connected with the anode of theADC chip; and the cathode of the MFC device is connected with the cathode of the Maker's duino core plate. The invention also provides an application method of the single-chamber air cathode MFC. Thepower generation efficiency is improved; zero pollution and zero discharge can be realized; it is not required to dissipate energy for aeration, and the establishing and running cost is lower; a detection voltage system developed on the basis of an Ardiuno detection platform is optimized to realize cloud voltage monitoring; and the research cost of a microbiological fuel cell is reduced, a new detection means is provided, and experimental staff can monitor the voltage and analyze data in real time.

Description

technical field [0001] The invention relates to the field of single-chamber air cathode MFC, in particular to a method for using the single-chamber air cathode MFC. Background technique [0002] Microbial fuel cells (MFC) are devices that use microorganisms as anode catalysts to directly convert chemical energy in organic matter into electrical energy. , a wide range of applications and other advantages. At present, MFC is mostly used in the field of wastewater treatment. It is an effective way to alleviate the current energy crisis and solve environmental pollution problems while processing organic wastewater. In recent years, my country's beer industry has developed rapidly, and its output has ranked first in the world for many years in a row. At the same time, the amount of wastewater generated in its production has also increased. Based on the high concentration of organic and non-toxic components in beer wastewater, electrogenic bacteria are used to oxidize and decomp...
