The aim of this paper was to apply and validate a model for measuring the rate and extent of anaerobic digestion, composting and CH oxidation in laboratory scale beds. Degradation studies were performed in four reactors each packed with shredded unsorted municipal solid waste, with one bed covered with a 100 mm layer of soil. The rates of production of CH, CO, C-CO and the rate of consumption of O were measured and used as inputs to a mass balance expressions for these components to calculate the rates of anaerobic digestion, composting and CH oxidation. The results showed that anaerobic digestion, composting and CH oxidation occurred simultaneously in both the covered and uncovered beds. The analysis showed that 50 ± 4% of the solids (COD basis) in the uncovered beds degraded anaerobically, with the generated CH subsequently oxidized, and that 32 ± 4% of the solids degraded aerobically in the covered bed.
本文旨在应用和验证一种用于测量实验室规模床中厌氧消化、堆肥和 CH 氧化的速率和程度的模型。降解研究在四个反应器中进行，每个反应器中都填充有切碎的未分类城市固体废物，其中一个床覆盖有 100mm 厚的土壤层。测量了 CH、CO、C-CO 的产生速率和 O 的消耗速率，并将其用作这些成分的质量平衡表达式的输入，以计算厌氧消化、堆肥和 CH 氧化的速率。结果表明，覆盖和未覆盖的床中同时发生了厌氧消化、堆肥和 CH 氧化。分析表明，未覆盖床中 50±4%的固体（以 COD 为基础）进行了厌氧降解，生成的 CH 随后被氧化，而覆盖床中 32±4%的固体进行了好氧降解。
