A control strategy of SN-SBR treating domestic wastewater was developed.
The aeration time of SN-SBR was calculated using a developed equation.
Using the control strategy, SN-SBR kept stable regardless of the influent variation.
The inhibition of NOB in SN process was significant.
The TN removal rate of the SN-anammox system achieved 91.7 ± 0.4%.
