[Methodological study on calibrating and validating model parameters of MUCT processes at low C/N ratio].

Basing on ASM2d, established a mathematical model to describe the transformation of COD, TN, NH4(+)-N and TP. In terms of comparison between simulation and observed values, the kinetics and stoichiometric parameters were established in MUCT process treating a wastewater with low C/N ratio. The results showed that, the q(PHA), K(A), K(pp), Y(PO4(3-), micro(AUT) and eta(NO3(-) were 2.90 g x (g x d)(-1), 3.85 g x m(-3), 1.35 g x (g x d)(-1), 0.35, 1.6 and 0.8, respectively. The typical parameters given by the ASM2d were used as others kinetic and stoichiometric parameters.
