-
摘要: 通过对北京某城市污水厂的曝气池各单元及二沉池营养物质变化进行跟踪试验,分析该污水厂的活性污泥单元倒置AAO工艺部分碳、氮、磷的物料流向,并且基于物料平衡分析了工艺中的能量流向。Abstract: 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.
