Abstract: This paper provides an overview of the technical achievements in A²/O upgrading during the 11th and 12th Five-Year Plans as well as the current successful operation of the improved A²/O process. We summarize the measures used for upgrading the A²/O process of municipal wastewater treatment plants under high discharge standards with respect to in-situ optimization and advanced treatment. Finally, we review the operating state of representative A²/O upgrade demonstration projects and offer suggestions for optimization and promotion of the A²/O process.
