In this work, a respirometric approach, i.e., Dynamic Respiration Index (DRI), was used to predict the anaerobic biogas potential (ABP), studying 46 waste samples coming directly from MBT full-scale plants. A significant linear regression model was obtained by a jackknife approach: ABP=(34.4+/-2.5)+(0.109+/-0.003).DRI. The comparison of the model of this work with those of the previous works using a different respirometric approach (Sapromat-AT(4)), allowed obtaining similar results and carrying out direct comparison of different limits to accept treated waste in landfill, proposed in the literature. The results indicated that on an average, MBT treatment allowed 56% of ABP reduction after 4weeks of treatment, and 79% reduction after 12weeks of treatment. The obtainment of another regression model allowed transforming Sapromat-AT(4) limit in DRI units, and achieving a description of the kinetics of DRI and the corresponding ABP reductions vs. MBT treatment-time.
在这项工作中，采用了呼吸计量法，即动态呼吸指数（DRI），来预测厌氧生物沼气潜力（ABP），研究了直接来自 MBT 全规模工厂的 46 个废物样本。通过一种插孔法获得了一个显著的线性回归模型：ABP=（34.4+/-2.5）+（0.109+/-0.003）。DRI。将这项工作的模型与使用不同呼吸计量法（Sapromat-AT（4））的先前工作的模型进行比较，得出了相似的结果，并能够对文献中提出的不同可接受填埋处理废物的限制进行直接比较。结果表明，MBT 处理平均允许在 4 周的处理后减少 56%的 ABP，在 12 周的处理后减少 79%。获得另一个回归模型允许将 Sapromat-AT（4）限制转换为 DRI 单位，并实现对 DRI 动力学及其与 MBT 处理时间的相应 ABP 减少的描述。
