Abstract :
Because of the special periodicity running mode of DE oxidation ditch, a running period is divided into 4 stages, and an ASM1-based instantaneous model is constructed to the system `Anaerobic Selection Tank + DE Oxidation Ditch + Final Sedimentation Tank´. Simulation is made with default parameters by MATLAB program. The results show that variation trend of COD and NH4-N accorded with practical situation. But variation trend of NOx-N did not match well.
