This document summarizes a study on using Fenton oxidation to treat fresh leachate. The researchers determined the optimal conditions for Fenton oxidation through a series of experiments varying pH, ferrous sulfate dosage, hydrogen peroxide dosage, and reaction time. The maximum removal efficiencies achieved were 99.1% for turbidity, 86.3% for hardness, 85.1% for COD, and 99.3% for color under optimal conditions of pH 2.5, 1.5 g/L ferrous sulfate dosage, 3 mL/L hydrogen peroxide dosage, and a 40 minute reaction time. The study demonstrated that Fenton oxidation is an effective and feasible method for treating leachate.
