Material and energy flow of activated sludge in anoxic-anaerobic-aerobic system
倒置AAO工艺中物料及能量流向的研究

In this study the material flow of carbon, nitrogen and phosphorus in the activated sludge system of anoxic-anaerobic-aerobic was analyzed in a full-scale wastewater treatment plant, and the result shows low COD balance (75.8%), high P and N balance. Moreover the energy flow based on material balance was analyzed in this system.
