摘要:	本研究對象為TNCU活性污泥處理系統是透過微生物作用將水中碳、氮、去除及磷移除以達到滿足出流水標準之目的，而一般TNCU廢水處理系統屬半開放性的系統，外界環境變化皆會影響污水水質特性，且目前污水處理系統設計多使用穩態數學模式，污水廠操作方式皆是採用固定式操作與控制方法，而人工水質檢測與量測方法需要耗費大量的人力物力及財力，加上微生物本身菌群組成與微生物對各項物質能量轉化過程難以量化，無法應付系統進流與系統各槽水質水量隨著時間變動的動態污水處理系統。面對整個處理系統呈現高度複雜的關係，以利用系統動力模式在非穩定的動態系統比起傳統控制系統更兼具全面性與人性化。因此，本研究主要為將可量化非結構性問題的系統動力模式，以系統動力學概念分析系統內各項物質與微生物間的關連與運作機制，並以此為基礎發展與建立TNCU系統動力模式，作為系統動力模式運作之輸入參數並計算系統出流水質，以評量找出TNCU系統問題的原因，期望能提升系統出流水質的穩定度，以做為後續系統操作控制與維護管理TNCU系統正常運作之決策工具。。而本研究的TNCU系統應符合微生物反應作用機制的反應趨勢，也須符合污水處理系統達到同時去氮除磷的目的，因此，本研究的模式可應用於污水處理系統，藉由評量程序模擬不同調整後的系統條件，以滿足TNCU系統功能之目的。解決現今許多廢水處理場設計上沒有依據並且大多都根據設計者經驗去進行設計的問題。;The thesis of this research is the TNCU treatment system, which removes carbon, nitrogen, removal and phosphorus from water through the action of microorganisms in order to meet the purpose of running water standards. The general TNCU wastewater treatment system is a semi-open system, and the external environment changes. It will affect the characteristics of sewage water quality, and the current sewage treatment system design mostly uses steady-state mathematics. The sewage treatment plant operation method uses fixed operation and control methods, and the manual water quality detection and measurement methods require a lot of human resources, material resources, and financial resources. In addition, it is difficult to quantify the energy conversion process of various substances by the microbial flora composition and the microorganisms themselves, and cannot cope with the dynamic sewage treatment system where the inflow of the system and the water quality and quantity of the tanks of the system change. Facing the entire processing system, it presents a highly complex relationship, and it is more comprehensive and user-friendly than the traditional control system in the unstable dynamic system by using the system dynamic mode. Therefore, this research is mainly to analyze the system dynamics model can quantify non-structural problems, analyze the relationship and operation mechanism between various substances and microorganisms in the system with the concept of system dynamics, and develop and establish the TNCU system dynamic model based on this., As the input parameter of the system power mode operation and calculate the system output water quality to evaluate and find out the cause of the TNCU system problem. I expect it to improve the stability of the system output water quality for subsequent system operation control and maintenance management of the TNCU system Decision-making tool for normal operation. The TNCU system of this study should conform to the reaction trend of the microbial reaction mechanism, and it must also conform to the purpose of simultaneous nitrogen and phosphorus removal in the sewage treatment system. Therefore, the model of this study can apply to the sewage treatment system and simulated by the evaluation procedure. Different adjusted system conditions to meet the purpose of the TNCU system function. Solve the problems that many wastewater treatment plants have no basis in design and I designed most of them based on the experience of designers.
