During hydrous ethanol production from the sugar refinery industry in Mexico, vinasse is generated. Phenolic compounds and melanoidins contribute to its color and make degradation of the vinasse a difficult task. Although anaerobic digestion (AD) is feasible for vinasse treatment, the presence of recalcitrant compounds can be toxic or inhibitory for anaerobic microorganism. Therefore, this study presents new data on the coupled of the FBR (Fluidized Bed Bioreactor) to the UASB (Upflow Anaerobic Sludge Blanket) reactor under non-sterile conditions by . Nevertheless, for an industrial application, it is necessary to evaluate the performance in this kind of proposal system.
Therefore, this study used a FBR for the removal of phenolic compounds (67%) and COD (38%) at non-sterile conditions. Continuous operation of the FBR was successfully for 26 days according to the literature. When the FBR was coupled to the UASB reactor, we obtained a better quality of effluent, furthermore methane content and yield were 74% and 0.18 m CH/ kg COD respectively.
This study demonstrated the possibility of using for an industrial application the coupled of the FBR to the UASB reactor under non-sterile conditions. Continuous operation of the FBR was carried out successfully for 26 days, which is the highest value found in the literature.
在墨西哥制糖业生产含水乙醇的过程中会产生酒糟。酚类化合物和类黑素导致了酒糟的颜色，使得酒糟的降解成为一项艰巨的任务。尽管厌氧消化（AD）对于酒糟处理是可行的，但难降解化合物的存在可能对厌氧微生物有毒或具有抑制作用。因此，本研究通过在非无菌条件下将流化床生物反应器（FBR）与上流式厌氧污泥床（UASB）反应器耦合，给出了新的数据。然而，对于工业应用而言，有必要评估这种提议系统的性能。
因此，本研究在非无菌条件下使用FBR去除酚类化合物（67%）和化学需氧量（38%）。根据文献，FBR连续运行26天取得成功。当FBR与UASB反应器耦合时，我们获得了质量更好的出水，此外甲烷含量和产率分别为74%和0.18立方米甲烷/千克化学需氧量。
本研究证明了在非无菌条件下将FBR与UASB反应器耦合用于工业应用的可能性。FBR连续运行26天取得成功，这是文献中发现的最高值。
