本研究利用生物包陷 (entrapment)技術，固定混合微生物( mixed-microorganisms) 於三醋酸纖維酯 (cellulose triacetate) 上， 以此作為載體 (carrier)；將此載體填充固定於反應管柱內，進行食品有機廢水之處理。 本廢水處理系統 為連續式；且反應管柱之水流方式近於完全混合。本報告係研究本廢水處理系統處理食品有 機廢水時之動力學，求出本系統之動力學模式。分析結果顯示，本廢水處理系統之基質利用 率與入流水基質濃度之關係可以下式表示： U=K1 × So-K2 U: 基質利用率，單位 mg/L-hr K1: 常數，單位 1/hr So: 入流水 COD 濃度，單位 mg/L K2: 常數，單位 mg/L-hr。

　　　　　The present study used mixed microorganisms entrapped in cellulose triacetate as a carrier, and packed the carrier into a reactor column to treat organic wastewater from food industry. The wastewater treatment system was a continuous flow and completely mixed reactor column. The present study analyzed the kinetics of this wastewater treatment system. The result shows that the substrate utilization rate is proportional to the substrate concentration in the influent, and can be described as below: U=K1 × So-K2 U: substrate utilization rate, mg/L-hr K1=constant, 1/hr So: COD concentration in influent, mg/L K2:constant, mg/L-hr.
