• 中文摘要： 應用生物濾床法處理廢氣可取代傳統突氣汙染防制技術。本研究係以一實驗室規模之生物濾床探討其處理含三乙基胺汙染物廢氣之效率。濾床內填充之濾料主要為有機堆肥,並加入稻殼使氣體流動分布均勻及床壓降減低。本實驗將進料氣體中之三乙基胺濃度控制在0.32至3.45g/m/sup 3/,而氣體停留時間則介於12至90sec(氣體流速為1.12至7.91cm/s); 實驗結果顯示去除率會隨氣體流速及入口三乙基胺濃度的增加而降低。此生物濾床對三乙基胺之去除負荷可達 137g/(hr m/sup 3/),當進料負荷起過此臨界值後,高濃度之基質對微生物產生抑制作用而降低去除負荷。
• 英文摘要： Biofiltration process has been validated as a promising alternative to other conventional air pollution control technologies. The objective of this research was to investigate the biofiltration of waste gas streams containing malodorous triethylamine. The experiments were conducted in a laboratory-scale reactor with a mixture of sieved compost and chaff particles as the filter material. The chaff particles serve to ensure more homogeneous gas distribution and reduce the pressure drop across the biofilter. The concentration of triethylamine in the inlet gas was varied from 0.32 to 3.45g/m /sup 3/, while the gas residence time ranged from 12 to 90 sec (superficial gas velocity from 1.12 to 7.91cm/s). It was found that the removal efficiency increased with decreasing gas velocity or inlet triethylamine concentration. Moreover, the elimination capacity of this biofilter could reach up to 137g/(hr m/sup 3/). When the loading of triethylamine exceeded this critical value, substrate inhibition occurred and the elimination capacity decreased.
