Using Biomatrix Mechanism to Evaluate the Degradation of Nitrogen-Rich Wastewater in the Photosynthetic Reactor

[[abstract]]本團隊在100 年度由環保署補助嘉義縣環保局辦理「嘉義縣溪口鄉養猪業源頭 減量（猪廁所）試驗評估計畫」一案，在氨氮廢水資源回收-養藻試驗，將本團隊 厭氧醱酵產出之醱酵液做為營養源添加至光合生物反應器中，初步實驗結果發現能 有效提高光合反應器藻類的濃度。 經由上述結果，本計畫研究主題為「以生物矩陣法評估光合反應器處理高濃度 氮磷廢水之機制」，藉由生物矩陣法-高效率藻菌共生系統之方法，經優勢化藻種 馴養程序，了解光合生物反應器中藻菌共生系統機制，並以降解高濃度氮磷廢水為 指標，評估及建立高效率藻菌共生系統之光合生物反應器。計畫時間預計以二年完 成。 本研究擬以優勢藻菌共生程序將富高濃度氮磷廢水有效處理為可再利用之/資 源，建立高效率光合生物反應器操作系統，本研究計畫分為兩階段進行規劃：第一 階段以批次式培養進行藻菌共生系統測試，經由全因子設計方法及硝酸鹽氮降解趨 勢作為基準探討基質濃度及環境影響因子對藻菌共生之光合生物反應器降解硝酸 鹽氮之影響，分析水質與光合生物反應器中微生物之型態，評估與建立藻菌共生系 統共動態操作的啟動及初期環境因子條件；第二階段啟動連續式培養以驗證並規模 放大至實驗級光合生物反應器的動態操作系統，以實驗設計建立系統最佳化操作條 件(包括HRT、基質濃度..等的操作控制)，並進一步評估光合生物反應器處理高濃 度氮磷廢水之機制，探討生質物能資源化之最佳化操作及藻類回收再利用的機制， 以建構一套完整高效率光合生物反應器處理高濃度氮磷廢水之動態操作程序。[[abstract]]The purpose of this study will be to build up a photosynthesis process with symbiotic of algae and microorganisms for the degradation of nitrogen-rich wastewater. This process had set up in our laboratory for the treatment of pig manure. The process was seeded with aquaculture water and added with biological agents developed by Lay. The experimental results demonstrated that this process could significantly consume organic carbon and ammonium. This process also could closure high volatile suspended solid. Thus, two-step study will be fulfilled in this study for further understanding the role of microorganisms/bacteria and algae in this process. First, initial environmental factors for start-up the process will be studied according to an experimental design. Second, using a continuous mode to operate the process and to identify the environmental factors whether could be suitable for the process or not.[[note]]NSC101-2221-E327-009-MY
