Abstract

Hydrogen peroxide and ferrous sulfate were used to advanced treatment of landfill leachate effluent from biochemical tanks. Some influences on removing COD and chroma including the pH value of solution, the dosage of ferrous sulfate, the dosage of hydrogen peroxide and reaction time were investigated. The test results showed that for removal of COD and chroma the optimal pH was 3.0, the best ferrous sulfate and hydrogen peroxide dosage was 1500mg/L, 20mL/L respectively, and the optimal reaction time was 60min. Under optimal conditions, COD and chroma removal rate could reach 79.7% and 95.2% respectively.

Keywords: Ferrous sulfate, hydrogen peroxide, landfill leachateC.
