【 摘 要 】

An alternativefor landfill leachate treatment are advanced oxidation processes by Fenton'sreagent (AOP/Fenton). In this context, the aim of this paper was to evaluate,in a bench scale, the treatability of leachate pós-AOP/Fenton characterizingthe supernatant and the sludge generated separately. Observed in optimal conditions,high removal efficiency of COD (76.7%), real color (76.4%) and humic substances(50%). Organic compounds were detected in the sludge (2.465 mg COD L-1)and high concentration of iron (1.757 mg L-1) as was expected. Finally,the sludge generated showed low settling hindering their separation by sedimentation(SVI = 321 mL g-1).
