Abstract:	本研究利用無氧-好氧MBR系統以處理垃圾滲出水。於固定水力停留時間 (HRT) 48小時、固定污泥停留時間 (SRT) 50天、迴流比為2Q等條件下，探討此些變數下各項水質參數之變化情形。實驗過程中檢測進流、Anoxic槽、MBR、出流水各槽參數之變化，檢測項目包含溫度、pH、溶氧、濁度、鹼度、懸浮固體物、揮發性固體物、化學需氧量 (COD)、總凱氏氮 (TKN)、氨氮、有機氮、亞硝酸鹽氮、硝酸鹽氮。本系統沿用先前學姐(王怡婷, 2010)所設定之條件，系統污泥停留時間(SRT)為50天，MBR槽與Anoxic槽之間迴流比為2Q(Q=7.5流量)，持續觀察系統穩定後其中水質參數之變化。結果顯示，系統處理過後COD、TKN、有機氮、氨氮、總氮，其去除率分別為，75%、83%、80%、92%、82%，系統處理後之出流水濁度為1.21~5.32 NTU，濁度去除率可達99.8 %。 MBR槽COD、TKN、有機氮、氨氮、總氮，其去除率分別為，84%、91%、90%、91%、85%。整體而言，系統之硝化作用佳，對於硝酸鹽氮有明顯之去除效果，且系統中溫度、pH與溶氧值也都維持於有利硝化作用與脫硝作用之進行範圍內。 This study aims at the leachate wastewater treatment by an anaerobic-aerobic multi-processed. The HRT and SRT of this study were controlled around at 48 hrs and 50 days. In addition, the water recycle ratio of this system was set at 2Q. These conditions mentioned above were collected from a previous experiment of laboratory. The determination parameters of inflow and outflow parameters in Anoxic/MBR tanks were temperature, DO, turbidity, alkalinity, suspended solid, volatile solid, chemical oxygen demand (COD), total kelvin nitrogen (TKN), ammonia nitrogen, organic nitrogenous, nitrite nitrogen and nitrate nitrogen. The result showed that removal efficiency of COD，TKN，organic nitrogenous，ammonia nitrogen and total nitrogen in overall system were 75%, 83%, 80%, 92%, and 82%, respectively. Moreover, the turbidity in this multi-system could reach 99.8%. In conclusion, this anaerobic-aerobic multi-processes could attained better nitrification and good removal efficiency for nitrate nitrogen, the temperature, pH and DO value in this system could maintained in stable range which was favorable to nitrification process.
