Open publisher page 0 citations

Abstract

Coagulation and Fenton combined methods were used to treat the landfill leachate.The optimum dosage of PAC and FeSO4 was obtained by the experiment.The factors of Fenton reaction such as initial pH,the dosage of FeSO4,the mole ratio of H2O2/Fe2+ etc were studied by experiments.The results show that under the optimum conditions,PAC-Fenton and FeSO4-Fenton process on COD removal rate can reach 91.4% and 90.3% respectively,in which FeSO4 coagulation-Fenton process is more advantageous in industrial applications.
