摘要：

The removal of molasses-derived melanoidin in alcohol distillery wastes was studied using a commercial inorganic flocculant with a chemical formula of [Fe2(OH)n(SO4)3-n/2]m. Decolorization yields of 32, 87 and 94% were obtained for fresh slops and for biodigester and lagooned effluents, respectively, at a flocculant dosage of 4% v/v. The reduction in total organic carbon (TOC) was 21% for fresh slops and averaged to more than 73% for the biodigester and lagooned effluents. The presence of relatively high amounts of fluoride ions affected the decolorization of fresh slops; supplementing CaO at a rate of 30 g/l improved the decolarization of the distillery slops, resulting to 93% color removal.
