The anoxic tank was packed with sponge pellets and followed by an aerobic membrane bioreactor (AMBR) to conduct a microbial enhancement system. Several parameters were examined to evaluate the system performance including MLSS, COD and ammonia-nitrogen. The average flow rate of this pilot plant was 3 CMD and an average membrane flux was maintained at around 12 L/m2-H, a total HRT of this system was controlled at 5 days. 20000 sponge pellets with a dimension of 0.5cm×0.5cm×0.5cm for each pellet were packed in the first tank without aeration. A PTFE membrane was employed for the membrane bioreactor and a suction/relaxation operation mode of 9/1 min was applied in this unit. A 300-day trial run was carried out to examine the system flexibility and permeate quality of this system. The results of this study showed that an average COD of permeate was 130 mg/L and ammonia-nitrogen removal was up to 99%. All the field data indicated that the effluent of this microbial enhancement system can meet the discharge requirement and has the scale-up potential to replace the current units including activated sludge process and activated carbon absorption unit. This study revealed that this microbial enhancement system is more economic and flexible than traditional process on bio-refractory wastewater, and this potenial process can play as an alternative for landfill leachate treatment to meet the strict standard in the future.
