A methodology to estimate disintegration and hydrolysis kinetic parameters of solid wastes and validate an ADM1-based anaerobic co-digestion model is presented. Kinetic parameters of the model were calibrated from batch reactor experiments treating individually fruit and vegetable wastes (among other residues) following a new protocol for batch tests. In addition, decoupled disintegration kinetics for readily and slowly biodegradable fractions of solid wastes was considered. Calibrated parameters from batch assays of individual substrates were used to validate the model for a semi-continuous co-digestion operation treating simultaneously 5 fruit and vegetable wastes. The semi-continuous experiment was carried out in a lab-scale CSTR reactor for 15 weeks at organic loading rate ranging between 2.0 and 4.7 gVS/Ld. The model (built in Matlab/Simulink) fit to a large extent the experimental results in both batch and semi-continuous mode and served as a powerful tool to simulate the digestion or co-digestion of solid wastes.
本文提出了一种估算固体废物分解和水解动力学参数并验证基于ADM1的厌氧共消化模型的方法。该模型的动力学参数通过分批反应器实验进行校准，实验按照一种新的分批测试方案分别处理水果和蔬菜废物（以及其他残渣）。此外，还考虑了固体废物易生物降解部分和难生物降解部分的解耦分解动力学。将单个底物的分批试验校准参数用于验证同时处理5种水果和蔬菜废物的半连续共消化操作模型。半连续实验在实验室规模的CSTR反应器中进行，持续15周，有机负荷率在2.0至4.7 gVS/Ld之间。该模型（用Matlab/Simulink构建）在很大程度上拟合了分批和半连续模式下的实验结果，并成为模拟固体废物消化或共消化的有力工具。
