| Summary: | 碩士 === 嘉南藥理科技大學 === 環境工程與科學系暨研究所 === 99 === 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.
