摘要: Model of a full-scale activated sludge process in WWTP Chongqing, China was established by coupling Activated Sludge No.2 (ASM2) and secondary settling tank (SST) model. Influent COD the ASM2 characterized through combined respirometric physical-chemical assay model parameters were calibrated after evaluating their structural identifiability. The SST is flux based on consistent modeling methodology, which more detailed velocity function proposed to describe most phenomena happened SST, including discrete floc, zone settling, compression settling. used simulate optimize operation It concluded that: 1) effluent COD, SS, TN TP could be simulated well, 2) recycle ratio concentration bioreactor optimized reduce waste sludge, increase capability resist load shocks lower temperature, improve quality, 3) an A2/O processes upgrade for improving efficiency N P removal.
