Abstract

Based on Activated Sludge Model NO.1 (ASM1) in wastewater treatment plant (WWTP), the models of single-feed and step-feed process were established. The components removals in two types of feed processes were simulated by Matlab Simulink. The results show that organic matter removal and heterotrophic organisms growing can benefit from single-feed process, while the step-feed process will promote ammonia nitrogen removal and autotrophic organisms growing. Simulation shows that the increment of XBA in step-feed process can be 0.4% higher than that in single-feed. The oxygen uptake rate of nitrification (NOUR) in WWTP shows that the step-feed process can effectively upgrade the NOUR which XBA can reach to 695 mgO₂/(Lúd), 1.96 times higher than the average value of another 4 WWTPs with single-feed process.
