dc.description.abstractThe aim of this study was to investigate the treatment efficiency of two laboratory scale vertical-flow wetland systems (VFWS) with/without additional carbon source to affect the denitrification of landfill leachate, taken from an active 15 years old landfill for municipal solid wastes. The BOD/COD ratio of the leachate was 0.26, which means predominance of slowly biodegradable substances. During the experiments the parameters COD, BOD, [NH4-N], [NO2-N], [NO3-N] and total phosphorus were determined. Significant removal efficiency according to COD (94.69 ± 2.5 %) and BOD (95.96 ± 2.5 %) was achieved. Complete nitrification of ammonium nitrogen into nitrite and nitrate occurred in both systems. Denitrification occurred only in the wetland system when methanol was added.
