Experimental Study on Anaerobic Biodegradability of Municipal Landfill Leachate

This study was to explore the feasibility of municipal waste disposal by anaerobic biodegradation. Experiment was conducted on anaerobic granular sludge digestion using liquid replacement equipment. The study results show that, leachate was at high level of anaerobic degradation activity during the initial 27 hours. In this experiment, methane conversion rate M% of landfill leachate could reach 62.2%, and anaerobic biodegradability BD % could be 76.4%, indicating that anaerobic degradation could be used for the disposal of landfill leachate, while the reaction period for anaerobic degradation should be 27 hours or less.
