| Abstract |
The purpose of this study is to investigate the high strength ammonia oxidation of piggery wastewater. Laboratory scale reactors was operated using influent of piggery wastewater and effluent of anaerobic digester from piggery wastewater at 35℃ and 20℃. Results of various operating conditions were compared and analyzed. After analyzing the results, effluent of anaerobic digester from piggery wastewater required shorter Solid retention time (SRT) than influent of piggery wastewater. In terms of the temperature, stable ammonia removal and denitrification was achieved on the both of the condition. At the temperature of 35℃, nitrite conversion rate was better than 20℃. It can be concluded that treating the piggery wastewater using anaerobic digester on the condition of the temperature at 35℃ is more efficient on the nitritation of the piggery wastewater. |
