AQUASIM 2.1 was used as the interface of mathematical calculations to develop the simulation model. Specifically, the Mixed Reactor and Saturated Soil Column were linked with the Biofilm Reactor respectively as two different types of hydrologic systems. The equations of biochemical processes in wetlands were combined into two hydrologic systems respectively to develop water quality simulation models for constructed wetlands.ield sampling data conducted by Guo(2009) were applied in this study for model calibration and validation. To improve the efficiency of model calibration and realize the major factors of water quality in wetlands, sensitivity analysis of parameters in each nutrient cycle was performed before model calibration stage. The error comparison between the simulation and measured outflow concentrations was carried on through statistical analysis to validate the availability of the model. Consequently, the results of the study, including the finding of feasible ranges for major affecting parameter values and the predicted water treatment efficiencies of constructed wetlands with various designs, are expected to give some valuable information for design, construction, manipulation, management, and diagnosis of constructed wetlands in the future.目 次試委員會審定書誌 I文摘要 IIIBSTRACT IV 錄 V目錄 VII目錄 X一章 緒論 1.1前言 1.2 研究目的 2.3 溼地 2.3.1 人工溼地 3.3.2 人工溼地水質淨化機制 5.3.3 礫間接觸處理法 6二章 文獻回顧 13.1 人工溼地現地實驗 13.2 人工溼地數值模擬 14.3 AQUASIM相關研究 15三章 研究方法與步驟 23.1 AQUASIM 23.2水質模式架構 24.2.1混合反應槽(零維模式) 24.2.2 飽和土體(一維模式) 25.3 生物膜 26.3.1生物膜模式架構 27.3.2生物膜生物作用模式 33.4 溼地內生物、化學、物理機制之模擬 35.4.1 模式變數與參數 35.4.2 人工溼地消耗營養物質之數學模式 43.4.3 計量矩陣 56.4.4 人工溼地動態水質模式 56.5 模式之誤差來源 57.6模擬資料 58.6.1 實驗溼地背景資料 58.6.2 實驗目的 58.6.3人工溼地設計規格 59四章 參數檢驗與模式驗證 81.1敏感度分析 81.3水質模式比較 85五章 結果討論 106.1模式結果討論 106.2生物膜模式之影響評估 108.3 飽和土體水質模式(一維)之貢獻 109六章 結論與建議 115.1結論 115.2建議 117考文獻 120錄 128application/pdf2970723 bytesapplication/pdfen-US地下流式人工溼地水質模擬生物膜AQUASIM牡蠣殼Subsurface flow constructed wetlandWater quality simulationBiofilmOyster shell[SDGs]SDG15thesishttp://ntur.lib.ntu.edu.tw/bitstream/246246/181157/1/ntu-98-R96622022-1.pdf
