This study was conducted to investigate the treatment performance of anaerobic organism for stabilized leachate under ambient air condition. The treatability of landfill leachate was tested under various influences including pH, dosage of anaerobic organism and contact time. Laboratory experiment revealed that anaerobic organism was in progressive state when the leachate in neutral condition. At this phase, the removal efficiency of chemical oxygen demand (COD), ammoniacal nitrogen (NH3–N) and colour of 76.84, 59.44 and 46.2?%, were experimentally attained. The experimental results also showed that the the optimum variables condition was established at pH 7 of leachate sample, dosage of 100?mL of anaerobic organism and required 14?days to reduce the COD, NH3–N and colour pollutants to 65.5, 60.2 and 46.3?%, respectively. The preliminary investigation shows that the anaerobic organisms were able to remediate leachate pollutants by the microbial activity in the leachate sample under ambient air condition.
