The application of reversed A2/O process in practice in China is mainly discussed in this paper. As a new process on nitrogen and phosphorus removal, principle and technical features of reversed A2/O process are also summarized. The application in rebuilt wastewater treatment plant shows that reversed A2/O process not only has merits on high nitrogen and phosphorus removal efficiency, but also has merits on energy saving. The application in newly-build wastewater treatment plant shows that infrastructure and equipment investment of reversed A2/O process economized 15% and 10% respectively, compared to conventional A2/O process. The practical application shows that reversed A2/O process is a new nitrogen and phosphorus removal process, which is suitable for China's national conditions.
