• 中文摘要： 熱交換器型之厭氣性生物膜反應器(HEABR)的性能在理論和實驗方面均加以探討。對於自行配製的低強度模擬廢水之處理,當實驗操作範圍在管壁溫度 25.degree.C-37.degree.C.,進口溫度 5.degree.C-15.degree.C及碳源負荷0.2克碳/(升.bcdot.日)-0.8克碳/(升.bcdot.日),都是可行的。而去除效率在70-98%之間。其操作性能與管壁溫度和水力滯留時間皆有密切關係,而當水力滯留時間短時,則與進口溫度無關。反應器模式之建立乃考慮細菌在生物膜和液體中進行一串聯式反應,對於反應溫度,主要基質擴散速率與中間產物的影響,均在模式中加以考慮。由實驗數據與理論計算結果之一致性,顯示此模式是可行的。
• 英文摘要： The performance of a heat exchanger-type anaerobic biofilm reactor (HEABR) was theoretically and experimentally studied. The treatment of a relatively low-strength artificial wastewater was experimentally feasible for a range of wall temperatures varying from 25.degree. to 37.degree.C, inlet temperatures varying from 5.degree. to 15.degree.C and loading rates varying from 0.2 to 0.8 g-C/ (l.bcdot.day). Removal efficiencies in the range of 70-98% were obtained. It was found that the performance of the reactor is strongly dependent on the wall temperatures and the hydraulic retention times and that the inlet temperature effect is smaller at low retention times. A reactor model was developed which considered that a consecutive reaction occurs both in the biofilm and the bulk liquid where the bacteria exist. The effects of temperature on the reaction and diffusion rates of the primary substrate and the intermediate product are also considered. A good fit between the experimental and calculated results showed the validity of the model.
