영문 초록

The objective of this study was to examine performance of the support media made of polypropylene in an fixed bed biofilm reactor for the treatment of synthetic sewage. After 18 h of seeding, biomass was attached on the surface of support media. Bioflm was formed within 2~3 days, but stable biofilm was abtained about 20 days. When organic loading rate was increased from 61.4 g BOD_5/㎡day to 102.9 g BOD_5/㎡day, the effluent BOD_5 and the biomass concentration was increased from 5.7 mg/ℓ to 9.7 mg/ℓ and from 50.1 g biomass/㎡ to 98.7 g biomass/㎡, respectively. At steady state effluent suspended solid was maintained below 2 mg/ℓ. The surface area of support media for desire effluent for a given conditions was expressed as a model equation below. 수식(원문참조) Prediction of the effluent BOD_5 values by using the mathematical model well agreed to the measured values.
