- Abstract:
- The multi?stage AO process has the advantages of high nitrogen removal efficiency and low return power consumption, and has been gradually applied in domestic wastewater treatment plants. The latest Technical Specification for Design of Membrane Bioreactor Process for Municipal Wastewater Treatment (T/CECS 152-2017) recommends two?stage or multi?stage AO?MBR process to be selected in process selection to improve denitrification performance. However, the calculation method of the multi?stage AO process is not clear in domestic standards. By contrast, the calculation method proposed by Japanese Sewage Works Agency gives a clear description of the process principle and values of the design parameter, and has been verified by many examples, which has strong practicability. Combined with the process design example of Futian wastewater treatment plant in Shenzhen, the calculation method of the multi?stage AO process based on Japanese Sewage Works Agency was introduced and compared with other calculation methods. It is considered that the process calculation method is simple and the future operation management is convenient under the equal proportion inflow.
