In this study, Anaerobic Digestion Model No.1 (ADM1) was modified to incorporate changes in biochemical parameters due to solids retention time (SRT) variations. Cattle manure (CM) and thermally hydrolyzed CM were selected for testing. Continuous anaerobic digestion reactors were operated under different SRT conditions ranging from 6.6 to 36.0 days for both samples. The biochemical parameters (, , , , , , , , , , and ) for each SRT condition were determined. To modify ADM1, the equations obtained through linear regression were substituted into biochemical parameters as a function of SRT. The modified ADM1 demonstrated superior accuracy compared with conventional ADM1. This study implies the feasibility of optimizing biochemical parameters for modeling in response to changes in environmental variables.

厌氧消化模型 1 号的修改，用于模拟改变固体保留时间的牛粪厌氧消化


在本研究中，对厌氧消化模型 1 (ADM1) 进行了修改，以纳入由于固体保留时间 (SRT) 变化而导致的生化参数变化。选择牛粪（CM）和热水解CM进行测试。两个样品的连续厌氧消化反应器在 6.6 至 36.0 天的不同 SRT 条件下运行。确定每个 SRT 条件的生化参数（、、、、、、、、、、、、和）。为了修改 ADM1，将通过线性回归获得的方程代入作为 SRT 函数的生化参数。与传统 ADM1 相比，改进后的 ADM1 表现出更高的精度。这项研究表明优化生化参数以响应环境变量变化进行建模的可行性。
