厌氧发酵甘蔗糖蜜生产沼气中试
|
摘要
糖蜜是甘蔗制糖过程中的一种副产品,主要用作动物饲料添加剂与生物制品的发酵原料。利用糖蜜生产沼气不仅拓宽了糖蜜的利用范围,还可以延长蔗糖生产链,发展生物质能源。本研究利用内循环(IC)反应器,并在试验后期加入外循环泵,探究糖蜜厌氧发酵产沼气的可行性。研究结果表明,在常温条件下,水力停留时间为5 d,进水COD_(cr)为5 000～10 000 mg/L,单日COD去除率最高达到了88.00%,沼气日产量最高可达2.4 m~3,沼气中的甲烷含量最高达49.8%。结果表明,厌氧发酵糖蜜生产沼气可行,并具有产业化的潜力。
Molasses is a by-product in the production of sugarcane-made sugar. It is mainly used as an animal feed additive and a fermentation raw material for the production of biological products. The application of molasses for biogas production not only broadens the use of molasses, but also extends the sugar production chain and develops biomass energy. In this study, an internal circulation(IC) reactor was used and an external circulation pump was added at the later stage to investigate the feasibility of biogas production by molasses anaerobic fermentation. The results showed that under normal temperature, the hydraulic residence time was 5 d, the influent COD_(cr) was 5 000～10 000 mg/L, the COD removal rate met 88.00%, the maximum daily biogas output was 2.4 m~3, and the methane content in the biogas was 49.8% maximumly. In conclusion, biogas production by molasses anaerobic fermentation is feasible and has potential for industrialization.
