Problems solved by technology

[0003] Due to the low power generation voltage of MFC in the existing wastewater treatment process, usually 250-400mV, it is difficult to fully recycle and utilize electric energy. At the same time, when the wastewater contains refractory organic matter, there are problems such as long start-up period and low success rate.

Description

technical field [0001] The invention belongs to the field of wastewater treatment, and in particular relates to a microbial fuel cell wastewater treatment system. Background technique [0002] Microbial fuel cell (MFC) is a technology that uses the catalysis of microorganisms to convert chemical energy in organic matter into electrical energy. The basic principle is: in the anaerobic environment of the anode chamber, organic matter decomposes under the action of microorganisms and releases electrons and protons. A current is formed at the cathode, and protons are transferred to the cathode through the proton exchange membrane, and the oxidant (usually oxygen) obtains electrons at the cathode and is reduced and combined with protons to form water. The reaction chamber of traditional MFCs is usually divided into an anode chamber and a cathode chamber by a separation membrane. Microorganisms process wastewater in the anode chamber and generate electrons. The cathode chamber ge...
