Paper Title:
Advanced Treatment of Stabilized Leachate by Sodium Hypochlorite Composite Chemicals
  Abstract

In this work, advanced treatment of leachate after biological treatment was performed using sodium hypochlorite solution (NaClO) + ferric chloride (FeCl3) + polyacrylamide (PAM) and NaClO + aluminum poly-chloride (PAC) + PAM, respectively, to determine the optimal condition for removal of COD and color. It was found that the optimal condition was: PAM 5 mg/L, FeCl3 420 mg/L, NaClO 6 mL/L, reaction time 15 min for treatment using FeCl3 + NaClO + PAM, and PAM 5 mg/L, PAC 800 mg/L, NaClO 6 mL/L, reaction time 15 min for PAC + NaClO + PAM. After being treated at the optimal conditions, the effluent quality met requirements of the tertiary grade described in “Integrated wastewater discharge standard”.
