Adsorption column was 100 cm height and 20 cm diameter. Leachate flowed through up to bottom and the treated leachate was collected for analysis. Results showed that adsorption equilibrium of chemical oxygen demand, color, ammonium nitrogen and Ca/Mg was reached at 10, 30, 40 and 8 bed volume. Adsorption intensity of heavy metals was found to be Cd > Pb > Cr > Zn > Ni > Cu. Treated leachate was examined for toxicology by Microtox test and the result showed that it did not reach the EC50. It is evident that activated carbon showed to have the adsorption capability of chemical oxygen demand, color, ammonium nitrogen and metals. It also showed that the treated leachate had not potential impact on environmental toxicity.
