Enhanced Coagulation for Landfill Leachate Pretreatment

W. K. Bai, F. Liu, H. You

Abstract

Coagulation was used in this paper to pretreat the waste incineration plant leachate to reduce the subsequent processing load. This work strengthened the traditional coagulation by compound coagulant and two-time coagulation. Results showed that the coagulation effect of poly aluminum chloride and polymeric ferric sulfate compound coagulant is better than that of polymeric aluminum chloride alone. The turbidity decreased from 74.0 NTU to 21.2 NTU, and the COD removal rate increased from 29.7% to 33%. In the case of the same dosage, the effect of two-time coagulation is stronger than that of one-time coagulation.
