摘　　要： 利用蕈菌云芝对不同稀释度酒精废液进行生物漂白及收获菌丝体研究。摇瓶培养结果表明,云芝对20%的酒精废液的脱色率为50%,生物量为8.1g/L。培养过程中培养液pH值呈上升趋势。利用5L发酵罐,通过控制发酵过程中pH值和通气量,培养54h,使脱色率上升到65%,生物量增加到10.9g/L,COD去除率为71%;通过检测发酵液中还原糖变化规律表明云芝对废水中的有色物质有分解利用的过程。与其他生物法处理酒精废液相比,云芝表现出较强的有机负荷承受能力、脱色能力及运行周期短的优势。 The decolorization capacity and production of mycelium of Coriolus versicolors cultured in different times diluted molasses spent wash were studied. The result of shake culture shows that 8.1 g/L of mycelium and 50% of decolorization rate could be gotten in 5 times diluted waste water by Coriolus versicolors. The pH value shows a raise tendency during cultivation. When Coriolus versicolors cultured in a 5 L bioreactor, through best control of ventilatory capacity and pH value, it could reach 65% of decolorization rate, 10.9 g/L of mycelium production and 71% of COD reduction after 54h of cultivation. The curve of glucose during cultivation shows that Coriolus versicolors is able to efficiently biodegrade colorants. Compared with other biotreatment of molasses spent wash, the treated waste water with Coriolus versicolors shows superity such as in COD reduction, more efficient biodegradation of colorants, higher biomass production and shorter cycle of process.
