A general methodology to implement fermentable soluble substrates in the IWA Anaerobic Digestion Model No. 1 (ADM1) that extends its application to anaerobic co-digestion of multiple substrates is presented. The approach considers the fermentation of new soluble substrates, not originally described in ADM1, as channelled through mass- and electron-balanced sugar fermentation equivalent reactions, and that fermentable substrates are degraded by a generic group of fermenters instead of the original ADM1 sugar fermenters. Therefore, no additional microbial group state is required. An additional term that modifies the ADM1 sugar fermentation kinetics equation was included to account for the competition among multiple substrates to be degraded by a particular biomass group. The model was validated at pilot scale treating a blend of pig manure (soluble fraction), wine and gelatine at mesophilic conditions. Only the ADM1 acetoclastic ammonia inhibition parameter was calibrated to obtain consistent model prediction of gas and liquid composition.
提出了一种将可发酵可溶性基质应用于 IWA 厌氧消化模型 No.1（ADM1）的通用方法，该方法扩展了其对多种基质厌氧共消化的应用。该方法考虑了新的可溶性基质的发酵，这些基质在 ADM1 中没有被描述，而是通过质量和电子平衡的糖发酵等效反应进行传递，并且可发酵基质由通用的发酵菌组而不是原始的 ADM1 糖发酵菌进行降解。因此，不需要额外的微生物组状态。增加了一个项来修改 ADM1 糖发酵动力学方程，以说明多种基质在被特定生物质组降解时的竞争。该模型在中温条件下处理猪粪（可溶性部分）、葡萄酒和明胶混合物的中试规模上进行了验证。仅对 ADM1 产乙酸氨抑制参数进行了校准，以获得气体和液体成分的一致模型预测。
