EVALUATE OF ADVANCED OXIDATIVE PROCESS BY FENTON REAGENT UNDER OPTIMIZED CONDITIONS FOR LANDFILL LEACHATE TREATMENT OF WITH EMPHASIS ON COLLECTIVE PARAMETERS AND CHARACTERIZATION OF SLUDGE GENERATED.

EVALUATE OF ADVANCED OXIDATIVE PROCESS BY FENTON REAGENT UNDER OPTIMIZED CONDITIONS FOR LANDFILL LEACHATE TREATMENT OF WITH EMPHASIS ON COLLECTIVE PARAMETERS AND CHARACTERIZATION OF SLUDGE GENERATED. An alternative for landfill leachate treatment are advanced oxidation processes by Fenton's reagent (AOP/Fenton). In this context, the aim of this paper was to evaluate, in a bench scale, the treatability of leachate pos-AOP/Fenton characterizing the 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)).
