The objective of this study was to invetigate the coagulation effects of landfill leachate by using Acid Mine Drainage(AMD). The coagulation efficiency was investigated by mixing landfill leachate with Fe^+3 solution earned by oxidation of pyrite(AMD). In the results of this experiment, it was found that the amount of removed COD and SS was approximately 30% respectively by mixing at the ratio of AMD three to leachate one. And it showed highest turbidity removal efficiency at all mixing ratio. Concentration of Fe was decreased with increasing mixing ratio, however it was increased inversely at mixing ratio 4. Optimal mixing ratio was 3 at the results obtained by leachate coagulation experiments. Also removal efficiency at mixing ratio 3 corresponded to 500 mg/ℓ of FeCl_3 dosage. It was suggested that pretreatment by mixing of AMD and leachate remove both suspended organic material of leachate and metal of AMD.
