This study was carried to investigate the milk-wastewater treatment in batch and continuous fluidized-bed bioreactor containing active microorganism, Aspergillus niger KCTC 1231. The reactor was operated at 30℃. The COD removal efficiency and MLSS were measured to determine the performance of the fluidized-bed bioreactor by cell concentration, aeration rate, and organic loading rate, respectively. At conditions of 60 ㎖ cell concentration and 2.0LPM aeration rate, milk-wastewater showed the COD removal efficiency of 81.51% and MLSS of 43,562 mg/ℓ, Also the same conditions, at adding 80 ㎖ chitosan beads, the COD removal efficiency and MLSS were about 85.79% and 62,482.5 mg/ℓ, respectively. In case of organic loading rate 3.88 kgCOD/㎥·day, free cell and adding chitosan beads showed about 80∼85% and 85∼90% COD removal efficiency, respectively. It was showed that milk-wastewater treatment of fluidized-bed bioreactor with chitosan beads was about 5% more efficient.
