Abstract

Photo-Fenton treatment of amature landfill leachatewas optimized by using the response surfacemethodology
(RSM). The optimum operating variables to achieve 70%removal of COD, 80%removal of colour and 80%
removal of NH3-N were: H2O2/CODmolar ratio 3.75, H2O2/Fe2+ molar ratio 10.5 and irradiation time 1.5 h.
There was good agreement (< 2%error) between experimental removal efficiency andmodel prediction.
The characteristics of the photo-Fenton treated leachate were: NH3-N 112 mg/L, colour 108 Pt-Co Unit,
COD350mg/L, BOD5 116mg/L andBOD5/CODratio 0.33, indicating that the treated leachatewas amenable
to biological treatment. The study has revealed thatRSMis an effective tool to optimize the treatment process
and photo-Fenton is an effective pretreatment ofmature landfill leachate for biological treatment.
