In this study, the results of the calibration of the complex activated sludge model implemented in BioWin software for the full-scale wastewater treatment plant are presented. Within the calibration of the model, sensitivity analysis of its parameters and the fractions of carbonaceous substrate were performed. In the steady-state and dynamic calibrations, a successful agreement between the measured and simulated values of the output variables was achieved. Sensitivity analysis revealed that upon the calculations of normalized sensitivity coefficient (S(i,j)) 17 (steady-state) or 19 (dynamic conditions) kinetic and stoichiometric parameters are sensitive. Most of them are associated with growth and decay of ordinary heterotrophic organisms and phosphorus accumulating organisms. The rankings of ten most sensitive parameters established on the basis of the calculations of the mean square sensitivity measure (δ(msqr)j) indicate that irrespective of the fact, whether the steady-state or dynamic calibration was performed, there is an agreement in the sensitivity of parameters.
本研究介绍了在 BioWin 软件中实现的复杂活性污泥模型的校准结果，该模型适用于全规模污水处理厂。在模型校准过程中，对其参数和碳源组分的分数进行了敏感性分析。在稳态和动态校准中，实现了输出变量的实测值和模拟值之间的良好一致性。敏感性分析表明，在计算归一化敏感性系数 (S(i,j)) 时，17 个（稳态）或 19 个（动态条件）动力学和化学计量参数是敏感的。其中大多数与普通异养生物和聚磷菌的生长和衰减有关。基于均方敏感性度量 (δ(msqr)j) 的计算，确定了十个最敏感参数的排名，表明无论进行稳态还是动态校准，参数的敏感性都是一致的。
