Abstract
A biologically activated carbon anaerobic reactor was applied for treatment of two types of food industry wastewater : low soluble COD concentration wastewater of 1000-1500㎎/L with high suspended solid of 300㎎/L, and bean paste production process wastewater. Mean total COD removal efficiency of 86% and 89% were obtained for both wastewaters under the fluidized-bed-volume organic loading rate of 0.5-33㎏ COD/(m3・d) and 1.6-29㎏ COD/(m3・d) respectively. It was indicated that conversion efficiency of removed soluble COD to solid COD was 0.12㎏ COD/㎏ COD-removed and the solubilization ratio of solid-COD was 95% for the low soluble COD concentration wastewater.
