Waste Leachate

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 2375.1mW.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.

To investigate the removal effect of pollutants in mariculture sediment by sediment microbial fuel cell (SMFC) and its power generation capacity, the effects of external resistance, cathode pH and cathode dissolved oxygen concentration (DO) on the SMFC system were investigated. The results showed that the optimal parameters for SMFC were as follows: external resistance = 1500 Ω, pH = 8.5 and DO = 5 mg·L-1. In these situations, the power generation performance and organic degradation effect were both the best. The maximum output voltages were 585, 606, and 587 mV, respectively; the removal rates of COD in sediment were 75.51%, 84.21% and 86.63%, respectively; and the removal rates of ammonia nitrogen in sediment were 80.34%, 98.91% and 90.24%, respectively. The SMFC system had a certain degradation ability to pollutants such as COD and ammonia nitrogen in the sediment of the marine aquaculture areas, which had a broad application prospect.
