Abstract糖蜜是一种制糖的副产物,富含备类有机物,常被用作发酵底物制备备类化工品,但鲜有用于制备生物燃气的报道。本研究采用糖蜜为底物以液态连续进料的方式实现了厌氧发酵的快速启动,COD去除率达70%以上,沼气产率达0.65m^3/kg以上,沼气甲烷含量达80%以上。该工艺可克服传统固体/半固体沼气发酵启动周期长,产气效率低等缺点,因此具有一定的产业化潜力。
Other AbstractMolasses is a by-product of sugar industry, which is rich in various organic compounds, and is often used as a substrate tbr the production of various chemicals, but little study uses molasses for biogas production. In this study, the rapid start-up of anaerobic fermentation was carried out by the liquid continuous feeding of molasses as substrate. For this technology, the COD removal was higher than 70 %, the biogas yield was higher than 0.65 m^3/kg, and the methane content in biogas was higher than 80 %. This technology can overcome the disadvantages of traditional solid/semi-solid methane fermentation, such as long start-up period and low gas production efficiency, thus has certain potential for industrialization.
