Zhao Shihui, the State Key Laboratory of Pulp and Paper Engineering, South China University of Technology, and others used anaerobic activated sludge as an inoculum to construct a potassium ferricyanide cathode microbial fuel cell (MFC), and studied the degradation of papermaking wastewater and the effect of electricity generation.
The results showed that after 146 h of glucose inoculation, the MFC was successfully started and a voltage of 360 mV was generated. The MFC with paper-making wastewater as substrate had a maximum power density of 14.2 mW/m2 for 160 h, and the CODCr removal rate of the wastewater reached 60.2%. Pulping wastewater can be used as a substrate for MFC, and it is effectively degraded at the same time as electricity generation. This provides a new way for low-energy treatment of papermaking wastewater.
