Solid-state anaerobic co-digestion of tomato residues with dairy manure and corn stover was conducted at 20% total solids under 35°C for 45days. Results showed digestion of mixed tomato residues with dairy manure and corn stover improved methane yields. The highest VS reduction (46.2%) and methane yield (415.4L/kg VSfeed) were achieved with the ternary mixtures of 33% corn stover, 54% dairy manure, and 13% tomato residues, lead to a 0.5-10.2-fold higher than that of individual feedstocks. Inhibition of volatile fatty acids (VFAs) to biogas production occurred when more than 40% tomato residues were added. The results indicated that ternary mixtures diluted the inhibitors that would otherwise cause inhibition in the digestion of tomato residues as a mono-feedstock.
采用 20%总固体在 35°C 下进行了番茄渣与奶牛粪和玉米秸秆的固态厌氧共消化，共 45 天。结果表明，混合番茄渣与奶牛粪和玉米秸秆的消化提高了甲烷产量。在 33%玉米秸秆、54%奶牛粪和 13%番茄渣的三元混合物中，VS 减少量最高（46.2%），甲烷产量（415.4L/kg VSfeed）最高，比单一原料高 0.5-10.2 倍。当添加超过 40%的番茄渣时，挥发性脂肪酸（VFAs）对沼气生产的抑制作用就会发生。结果表明，三元混合物稀释了抑制剂，否则这些抑制剂会抑制番茄渣作为单一原料进行消化。
