| 摘 要： | 该文以废弃的甘蓝菜叶为发酵原料,在实验室自行设计的小型沼气发酵装置上进行了厌氧发酵试验,通过测定发酵过程中发酵液和沼气的各项指标,对蔬菜废弃物厌氧发酵的可行性及接种物浓度对发酵过程的影响进行了研究.结果表明,蔬菜废弃物用厌氧发酵工艺处理是可行的;在试验采用的20%,30%,50%三个水平的接种物浓度中,接种物浓度为30%的实验组的挥发酸含量、氨态氮含量以及pH值都在正常范围内,总产气量和沼气中最高甲烷含量分别为7790.81 mL和42.814%,明显高于其他两组及空白组实验.该项研究对蔬菜废弃物的资源化利用提供了有益的参考.

| Abstract: | A batches of anaerobic digestion experiments for leaves of cabbage wastes were conducted in self-manufactured anaerobic fermentation equipment. The feasibility of anaerobic digestion disposal of leaves of cabbage wastes and the effect of different concentration inoculums on anaerobic digestion were studied. The results show that the anaerobic digestion can fit for the characteristics of anaerobic fermentation of vegetable wastes. Among inoculums concentrations of 20%, 30% and 50%, the contents of VFA, NH4+-N and pH value for the 30% inoculums concentration were normal, and the total biogas content and the maximum CH4 content were 7790.81 mL and 42.514%, respectively, which were obviously higher than those of other two treatments and control. This study provided a good reference for the research and development of the comprehensive utilization of vegetable waste. |
