    Abstract: 本研究結合膜離生物反應槽(Membrane bioreactor,MBR)與好/缺氧操作模式(Aerobic/Anoxic operation mode),針對ABS樹脂廢水中氮化物處理效率進行研究。研究結果得知,在TKN去除方面,Stage 1之去除效率為42±13.9%,Stage 2與Stage 3之去除效果分別為48.9±13.7% 與 54.4±13.7%。然而,TKN之去除效率為40~50%,且出流水亞硝酸與硝酸之濃度非常低,其可表示此系統中脫硝作用與硝酸化作用(nitratation,NO2-→ NO3-)顯著,但其亞硝酸化作用(nitritation,NH4+ → NO2-)有被抑制。氮系物種質量平衡方面發現,進流有機氮與氨氮總和皆佔氮系物種99~100%,於三階段操作模式下,Stage 1出流水之氨氮與有機氮分別佔系統總氮量51%與10%。Stage 2出流水之氨氮與有機氮分別佔系統總氮量33%與21%。Stage 3出流水之氨氮與有機氮分別佔系統總氮量27%與22%。整體上來看,以第三階段之去除效果為最佳。
