摘要：

This research aims to investigate the performance of the combined BPAC-MBR system for old-landfill leachate treatment. The system was operated at two different intermittent aeration modes (aeration or non-aeration) of 120-120 min and 150-150 min. It was found that the BPAC-MBR system operating at 150-150 min could give higher removal efficiencies for all parameters; COD at 83%, colour at 85%, TKN at 97%, and TP at 68%. The reason might be that the degradation mechanism of microorganisms inside the BPAC-MBR system needed sufficient time for sequential aerobic and anaerobic periods to improve biodegradation for slowly biodegradable organic compounds.
