| Basing on ASM2d, established a mathematical model to describe the transformation of COD, TN, NH+4-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 QPHA, KA, KPP, yPO3- 4, μAUT and ηNO- 3 were 2.90 g·（g·d）-1, 3.85 g·m-3 , 1.35 g·（g·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. |
