摘　　要：首先,通过理论分析对A/O工艺及SFA/O工艺的处理容量进行分析,对两种工艺的脱氮性能进行评价。在此基础上,在高C/N和低C/N下,通过试验验证两种工艺的脱氮性能及污泥沉降性能。结果表明,SFA/O工艺在与传统A/O工艺相比,无论在处理效果及长期运行的可行性上,均存在明显优势。SFA/O可作为一种深度脱氮工艺可应用到大中小型污水处理工程。To compare the nitrogen removal efficiency, the theoretical method was adopted to analye the treat- ment capacity between A/O process and SFA/O process. Based on the theoretical analysis, the nitrogen removal ef- ficiency and sludge settlement performance under the higher C/N ratio and lower C/N ratio was investigated re- spectively. The results showed that either the treatment efficiency or the feasibility of long-term operation, SFA/O process shows a strong advantage compare to A/O process. As a deep nitrogen removal process, SFA/O process can be used to wastewater treatment plant with large, medium and small scale.
