摘　　要：文章针对中试规模农村生产生活有机废弃物的厌氧消化过程,利用MATLAB进行ADM1模型的拟合仿真研究。结合投料方式,通过校准kLaCH_(4),kLaH_(2),kLaCO_(2)值,模拟序批式混合有机质厌氧消化过程中CH_(4),CO_(2)的产量。得到的累积产气量模型拟合度较好,R^(2)高于0.98。对CH_(4)和CO_(2)的单日产气量,以及由此计算得出的CH_(4)和CO_(2)浓度比值,也进行了拟合并讨论模型校准的效果。In this paper,aiming at the rural anaerobic digestion process of farming organic wastes and living organic wastes on a pilot scale,fitting simulation of ADM1 model by using MATLAB were studied.Combined with the feeding method,the production of CH_(4)and CO_(2)in the sequencing batch anaerobic digestion with mixed organic matter was simulated by calibrating the values of KlACH_(4),KlaH_(2)and KlACO_(2).The cumulative gas production model was well fitted with R^(2)greater than 0.98.The ratio of CH_(4)/CO_(2)concentration was calculated based on the daily production of CH_(4)and CO_(2),and the results of model calibration were discussed.
