摘要(中) 連續流循序批式活性污泥系統（Continuous-Flow Sequencing Batch Reactor, CFSBR）透過現地單槽式處理，解決下水道維護困難與建設的問題，為未來發展之趨勢。由於進流水水質、水量及環境條件會隨著時間變化，過去透過判斷pH與ORP反曲點以即時判斷微生物反應終點，以提升系統處理效益。但皆以靜態方式判斷折點，當進流水水質濃度高與微生物反應速率慢，導致微生物無法在限制時間內達反應之終點，造成系統無法達成處理之目的。且在系統運作初期，各反應相運作時間皆無擬定之依據，導致需要透過出流水水質結果持續修正，如此，造成時間與實驗成本的浪費。為了解決上述之問題，本研究欲建立一自動控制系統，透過系統動力模式依據進流水水質擬定操作策略，系統依據產出之操作策略運作，可將進流水水質處理至符合預期之水質，COD<100 mg/L、SS<30 mg/L及氨氮<10 mg/L。且透過建立控制策略擬定流程，可依據監測資訊與異常訊號，判斷系統問題與分析造成問題之原因，並產生解決對策，以及時解決進流水水質、水量及微生物隨時間改變與軟硬體異常之問題，藉此達成系統自動化之目的。 摘要(英) A CFSBR（Continuous-Flow Sequencing Batch Reactor）solve difficult problem of sewer of the construction and maintenance by using a single reactor on site. As a result of the influent of water of the quality, discharge of quantity and environmental conditions will change over time, in order toenhance the system processing efficiency, using pH and ORP broken point to judge microbial terminal point. When high concentrations of the influent water quality and microbial reaction rate is slow, judging microbial terminal point can’t make system achieve the purpose. In the initial period of operation and system produce strategy which make system operate without adequate foundation, so strategy need to sustained correction by analyzing result of the effluent, resulting in a waste of time and experimental costs. In this research is to establish an automatic control system, developed operating system dynamic model based strategy through the influent water quality for solve the above problems, and CFSBR base on strategy can beinfluent water treatment to meet the water quality expected, COD<100 mg/L,SS<30 mg/L and NH4+<10 mg/L. By creating a process to develop control strategies can be based on monitoring information and anomalies, determine system problems and analyze the causes of the problems caused and produce solution, as well as solve the influent of water of the quality, discharge of quantity and microbiological changes over time problems with hardware and software anomalies, thereby achieve the purpose of automation systems. 關鍵字(中) ★ 連續流循序批次活性污泥系統
