Based on the analyzing of the energy consumption of the AO and AAO units, the energy-saving strategies and ways of those AO and AAO WWTPs were studied. Specially, the optimization of water treatment facilities and the operational management, development and application of low carbon technology, as well as include source and reduce expenditure exploitation and systematic optimization were well discussed. At the end, the future challenges and suggestions were also given. These findings here are of great significance for the energy-saving operation of the AO and AAO wastewater treatment plants operation.
