Using Fenton Oxidation Method to Advanced Treatment of LandfillLeachate

摘要

Hydrogen peroxide and ferrous sulfate were used to advanced treatment of landfill leachate effluent frombiochemical tanks. Some influences on removing COD and chroma including the pH value of solution, the dosage offerrous sulfate, the dosage of hydrogen peroxide and reaction time were investigated. The test results showed that forremoval of COD and chroma the optimal pH was 3.0, the best ferrous sulfate and hydrogen peroxide dosage was1500mg/L, 20mL/L respectively, and the optimal reaction time was 60min. Under optimal conditions, COD and chromaremoval rate could reach 79.7% and 95.2% respectively.
