采用改进粒子群算法对 ADM1模型中的关键参数进行了估计，经敏感性分析，确定了 Monod最大比吸收速率、半饱和值、产物对底物的产率等3种参数对产酸速率具有较大影响。应用修正后的动力学参数对ADM1模型在不同C/N比调控下污泥厌氧发酵产酸结果进行了模拟。结果表明，模拟产酸数据和实测数据误差较小，说明修正后的ADM1模型能够很好地描述污泥厌氧发酵中C/N比条件对产酸的影响。

The improved particle swarm optimization (PSO) algorithm was used to estimate the key parameters of ADM1model. Through sensitivity analysis of key parameters, the Monod maximum uptake rate parameters km,i, half saturation constant Ks,i and the products yield from substrate fi were proved to be significant impact on the volatile fatty acids (VFAs) production. The revised kinetic parameters were integrated into the ADM1to modeling the VFAs production from anaerobic fermentation of sewage sludge by C/N regulation. The results indicated that the errors were low between the estimated and experimental determined VFAs production data, suggesting that the modified ADM1 model can be used to describe the effects of C/N regulation on the VFAs production from anaerobic digestion of sewage sludge well.
