High concentration of sulfate is an important factor affecting the degradation of molasses alcohol wastewater. This paper described the sulfate-reducing bacteria effect of anaerobic fermentation process and sulfate reduction products of the anaerobic methane fermentation mechanism. The characteristics of molasses alcohol sulfate anaerobic wastewater treatment process technology and applications were comprehensively reviewed. Combined with engineering cases, this article suggested the molasses wastewater anaerobic conversion process of high efficiency and low-cost to remove sulfate on the anaerobic fermentation inhibition technology in-depth study. Moreover, the industrial applications of biogas were also suggested.
