Municipal Solid Waste Leachate Treatment using Microbial Fuel Cell

摘要

Leachate is a high concentration organic wastewater, and microbial fuel cell (MFC) is capable of decomposing and treating organic pollutants directly. Single-chamber MFC using landfill leachate as anolyte was built to get rid of BOD and ammonia-nitrogen organic pollutant in leachate. The use of MFC led to the treatment of the biodegradable organic pollutant of municipal solid waste leachate and the production of electricity. The biofilm was detected on the MFC anode carbon felt, the voltage and power output were achieved 292.7±5 mV and 2375.1 mW·m~(-2). The suitable running time was about 10 days, when the BOD and ammonia-nitrogen removal efficiencies were achieved about 93.0% and 84.1%, respectively.
