In this paper the ADM1 model that has been developed by the IWA Task Group for Mathematical Modelling of Anaerobic Digestion Processes is summarized. The model was applied to a variety of anaerobic digestion scenarios that are presented in the literature and for each data set the model predictions were compared to experimental values. Based upon the model applications it was apparent that for accurate model simulations the influent sludge should be well characterized in terms of biodegradable and recalcitrant COD and also nitrogenous compounds. In almost all cases the model was able to reflect the trends that were observed in the experimental data however the concentrations of VFAs were consistently over-predicted in digesters with short SRTs. It would appear that the inhibition functions associated with low pH values tend to overestimate the impact of pH on biokinetic rates for the acid-consuming bacteria. Application of the model with flow through of active biomass between digesters in series in temperature-phased systems needs to be further evaluated in the future.
本文总结了国际水协厌氧消化过程数学建模任务组开发的ADM1模型。该模型应用于文献中呈现的各种厌氧消化场景，并将每个数据集的模型预测值与实验值进行了比较。基于模型应用，很明显，为了进行准确的模型模拟，进水污泥应在可生物降解和难降解化学需氧量以及含氮化合物方面得到很好的表征。在几乎所有情况下，该模型都能够反映实验数据中观察到的趋势，然而，在短污泥停留时间的消化器中，挥发性脂肪酸的浓度一直被高估。似乎与低pH值相关的抑制函数往往高估了pH值对耗酸细菌生物动力学速率的影响。未来需要进一步评估该模型在温度分段系统中串联消化器之间活性生物质流通的应用情况。
