為提昇連續流循序批分式活性污泥系統（ Continuous-Flow SequencingBatch Reactor, CFSBR）的整體處理效率及效益，本研究乃藉由低溶氧生物攝磷及硝化反應動力參數之分析，以評估其程序控制之可行性並界定成效
限制因子，並結合線上即時量測溶氧轉換比率（at）及系統需氧速率（ODt+Dt）用以表現微生物用氧行為與特性的探討，研擬即時曝氣控制的方法，以控
制CFSBR 系統於低溶氧環境中同時進行生物攝磷及氨硝化程序。研究結果顯示，CFSBR 系統之兼氣性微生物可被馴化及控制在低溶氧環境中進行生物攝磷及氨氮硝化程序。當微生物被馴化並控制在低溶氧環境進行生
物攝磷及氨氮硝化程序過程中，突增曝氣量或改變系統溶氧濃度，將會干擾生物攝磷機制及降低氨氮硝化的速率，導致脫氮除磷成效的惡化。厭氧相所需維持的氧化還原狀態為低溶氧生物攝磷及氨氮硝化程序之成效限
制因子。有效控制硝化產物以亞硝酸鹽及硝酸鹽的型式共同存在，且降低硝酸鹽與亞硝酸鹽的濃度比例，不僅可縮短缺氧脫硝反應的時間及促進脫硝反應的完全，同時可促使後續操作循環之厭氧相處於ORP < -250 mV 的氧化還原狀態，進而降低硝酸鹽對生物厭氧釋磷作用的抑制效應，使整體脫氮除磷效率大幅提昇。根據即時曝氣控制方法所量測之溶氧轉換比率與系統需氧速率等資訊，可瞭解CFSBR 系統微生物進行生物攝磷與硝化反應過程中的用氧行為，包括：系統溶氧進入微生物細胞以進行恢復代謝基質活性的時機、微生物活性恢復的機、及硝化反應型態等。結合上述的微生物用氧行為量測的方法修正即時曝氣控制方法，將可提高程序控制的穩定性與提昇整體操作效率及效益。

The purpose of this study is to develop a real-time aeration control method to
control the aerobic bio-phosphorus uptake and ammonia nitrogen nitrification
processes operated under low DO level conditions, to increase the
comprehensive performance of Continuous-Flow Sequencing Batch Reactor
(CFSBR). The study results showed the facultative organisms in CFSBR
could be acclimated and controlled under low DO levels and low ORP states to
perform the simultaneous bio-phosphorus uptake and ammonia nitrogen
nitrification processes, and high comprehensive performance of CFSBR were
obtained. The performance limiting factor of low DO level bio-phosphorus
uptake and nitrification processes is the ORP state in anaerobic phases.
Control the nitrified productions were coexistence of NO2
--N and NO3
--N, as
well as low NO3
--N/NO3
--N ratios were presented, could increase the efficiency
of the anoxic denitrification processes and eliminate the inhibition effects of
bio-phosphorus release in the anaerobic phases, thus increase the performance
of low level bio-phosphorus uptake and nitrification processes. The on-line
measured information of the oxygen transfer ratios and the oxygen demand rates could characterize the microbial oxygen utilization behaviors in the low DO level bio-phosphorus uptake and ammonia nitrogen nitrification processes.Integrate the on-line measured information of the oxygen transfer ratios and the oxygen demand rates into the real-time aeration control method could increase
the stability of process controls and the effectiveness of operations.
