A pilot-scale anaerobic membrane bioreactor (AnMBR) was designed and optimized for the treatment of real distillery wastewater. A low hydraulic retention time of 3.5 days was reached after only 3 weeks. The AnMBR could treat up to 3.97 gCOD/L/day with high biogas production at 1.36 NLbiogas/Lbioreactor/day. The performances of an AnMBR and an anaerobic packed-bed bioreactor for treating the same wastewater were compared. The AnMBR had a shorter start-up period (21 days), a higher COD removal efficiency (96.9 %), and higher stability and methane production (0.26 LCH4/gCODinput), indicating the interest of investigating AnMBR industrialization. The membrane performance was also studied, demonstrating a long cleaning cycle interval of at least 44 days. The transmembrane pressure and Food-to-Microorganism ratio were defined to minimize membrane fouling without affecting the anaerobic digestion performance.

厌氧膜生物反应器在中试规模处理酿酒废水中的优异性能

设计并优化了中规模厌氧膜生物反应器(AnMBR),用于处理实际的酿酒厂废水。仅3周后,达到了3.5天的低水力停留时间。在1.36 NL沼气/ L生物反应器/天的情况下,AnMBR可以处理高达3.97 g COD / L /天的高沼气产量。比较了AnMBR和厌氧填充床生物反应器处理相同废水的性能。AnMBR的启动时间较短(21天),COD去除效率较高(96.9%),稳定性和甲烷产量较高(0.26 L CH4 / g COD输入)),表明有兴趣研究AnMBR工业化。还研究了膜的性能,证明了至少44天的长清洁周期间隔。跨膜压力和食物与微生物的比例定义为在不影响厌氧消化性能的情况下最大程度地减少膜污染。
