摘要

以ASM2D为机理模型对活性污泥法脱氮除磷工艺进行优化设计，在满足出水水质标准的前提下，使总设计费用达到最低，对优化模型中的各种参数进行灵敏度分析。结果表明，不同种类参数的灵敏度差别很大，其中目标函数中各参数对结果影响最大，最大灵敏度达到-99.02%;进水组分、化学计量系数和动力学参数的最大灵敏度分别为16.06%、11.9%和7.60%。随着排放标准的下降，系统的总费用也随之减少。对优化设计中参数进行灵敏度分析可以得出一些重要参数对结果的影响程度，为参数校正和结果输出提供理论依据。

Abstract

ASM2D was used as mechanism model for optimizing the activated sludge nutrient removal process.For minimizing the total design cost under the premise of meeting emission standards

the sensitivity of each parameter in the optimization model was analysed.The sensitivity of different parameters varies greatly

in which the objective function has the largest impact on the design results with a sensitivity value of -99.02%.The maximum sensitivities of influent components

stoichiometric parameters and kinetic parameters are 16.06%

11.9% and 7.60%

respectively.With the decline of emission standards

the total cost also will be reduced.Through sensitivity analysis in optimization design

the influence extent of important parameters on the optimization results can be obtained

which also provide theoretical bases for parameters calibrating and results outputing.
