In this study, refractory leachate was treated using FeCl₃ and FeCl₃ + PAM, respectively, to study removal efficiency of CODcr, SS and colority of leachate as a function of such influencing factors as pH, dosage of FeCl₃ and/or PAM. It was found that optimal dosage and pH are 420 mg/L and 6 for FeCl₃. The optimal condition when using PAM + FeCl₃ for removal of CODcr was 15-minute reaction, pH of 5, FeCl₃ dosage of 420 mg/L, PAM dosage of 5 mg/L. Effluent quality after coagulation at the optimal conditions met requirements of the tertiary standard described in “Integrated wastewater discharge standard”. Coagulation using PAM + FeCl₃ at the optimal condition was recommended for advanced treatment of refractory leachate after biochemical treatment.
