Structural Effect of Landfill on Leachate Recirculation

This paper presents a pilot experiment involving four plots of landfill with different structures for examining the leachate recirculation effectiveness of different conditions, i.e. semi-aerobic and anaerobic, formed respectively due to the different structures of landfill. Results shows quasi-aerobic condition in general is better than the anaerobic in terms of COD and ammonia removals with leachate being recirculated, and the longer retention time of recycled leachate would help enhance recirculation effects.
