This paper reports on landfill leachate treatment by Fenton (Fe2+/H2O2) and solar photo-Fenton (Fe2+/H2O2/UV) processes in a pilot plant with compound parabolic collectors (CPCs). The solar photo-Fenton reaction is much more efficient than the respective dark reaction under identical experimental conditions, leading to 86% mineralization and 94% reduction of aromatic content of the leachate after 4 days of solar exposure (206 kJ(UV) L-1), consuming 366 mM of H2O2 in the presence of 20 mg L-1 of iron. According to activated sludge respirometry, BOD5/COD ratio, Zahn-Wellens and kinetic results, the amount of UV energy necessary to reach a biodegradable effluent is 113 kJ(UV) L-1, consuming 227 mM of H2O2, which means almost 73% mineralization of the leachate.
