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.

Key words: high discharge standard, municipal wastewater treatment plant, A2/O, upgrading, demonstration project
