Abstract :
Landfill leachate pre-treatment was studied by Fenton reagent composed of FeSO4ldr7H2O and H2O2. The different effect factors of CODcr were studied, such as pH value, Fenton reagent under different dosages, the molar ratio of ferrous ion to H2O2 and reaction time. The results indicated: when the pH value was 3.0, the dosages of H2O2 was 0.25 mol, FeSO4ldr7H2O and H2O2 in the molar proportion was 10 to 1 and reaction time was 1.5 hour, the higher CODcr removal efficiency was obtained, reached 64.7%.
