通过对番茄残茎、果、叶进行分批厌氧消化，评价番茄水培过程中植物残茎、果、叶的甲烷（ch4）气体回收潜力。在50天内，该底物的累积ch4气体产生量约为300 mL ch4 g VS-1，与实际使用中其他底物的产生量相当，说明分批AD回收番茄残渣的能量是可行的。比较并验证了两种不同的番茄残渣生成甲烷气体的动力学AD模型，以表征每种底物的AD特性，并获得放大后的AD装置稳定运行的知识。结果表明，在整个实验过程中，两池两步模型在数据拟合和过程信息方面优于一阶动力学模型。
Batch anaerobic digestion (AD) of residual stems, fruits and leaves of tomato plants was carried out to assess potential methane (CH 4) gas recovery from plant residues in tomato hydroponics. The cumulative CH 4 gas yielded from the substrates for fifty days was around 300 mL CH 4 g VS-1, which value is comparable to that from other substrates in practical use, indicating that the energy recovery from tomato residues through batch AD is feasible. Two different kinetic AD models for the generation of CH 4 gas from tomato residues were compared and verified to characterize AD of each substrate and obtain knowledge about stable operation of a scaled-up AD plant. The result shows that a 2-pool, 2-step model is superior to a first-order kinetic model in better data fitting and more process information throughout the experimental period.
