摘　　要：通过小型批量实验,对酵母菌处理穿山龙淀粉废水的工艺条件进行了研究。结果表明,采用优化发酵培养基,当初始pH值为5.5、培养温度为30℃、培养时间为48 h、接种量为1.0%、装液量为50 mL/250 mL时,干酵母产量最高可达10.34 g·L-1,废水CODCr去除率达80%以上。该技术操作简单,可作为预处理应用于实际生产中,并可回收酵母蛋白,具有一定的经济效益。酵母菌废水处理技术有望成为常规好氧和厌氧处理技术的重要补充而在工业废水治理中发挥重要作用。With small batch experiments, the technical conditions for treatment of Dioscoreae nipponicae starch manufacturing wastewater by yeast were studied. The results showed that the CODCr removal rate of the wastewater reached over 80%,and the maximum production of dry yeast could reach 10.34 g · L^-1 using the optimized fermentation medium under the following conditions.pH value 5.5, culture temperature 30℃, culture time 48 h, inoculation amount 1.0%,volume of installed solution 50 mL/250 mL. The operation of this technique is simple. It can be used as a pretreatment process in actual projects. Moreover,this technology has certain economic benefits on recovering yeast albumen, so it is expected to be a promising supplement for traditional aerobic and anaerobic wastewater treatment techniques to solve some intractable problems in industrial pollution.
