摘要：In this paper, the treatment of landfill leachate by Polymeric Ferric Silicate-Sulfate was studied with the landfill leachate of Shankou landfill in Guilin city as the research object. The orthogonal experiment shows that the influence of dosage of PFSS, pH and dosage of PAM on the treatment is decreasing in turn. The removal rate of COD, TP, SS reaches at 71.09%,99.13% and 97.54% when the original concentration of COD, TP, SS is 1442 mg/L,7.94 mg/L and 244 mg/L respectively by setting the optimum parameters of PFSS 20 ml/L, PAM 20 mg/L, pH 6.5. Adding enough PFSS is beneficial to the rapid release of CO₂ and the mud- water separation of flocculation, and avoid the influence of bubbles on the later separation of mud from water.
