摘　　要：研究了利用不同酵母菌株处理大米淀粉废水的效果,以及温度、pH、摇床转速对废水处理的影响。结果表明:利用产朊假丝酵母1087处理大米淀粉废水效果最佳。在不灭菌条件下,酵母菌接种量为5%、培养温度30℃、转速160 r/min的情况下,培养24 h后,大米淀粉废水pH从初始4.0上升至8.15,COD从6 250 mg/L降为3 087 mg/L,COD去除率为50.5%。产朊假丝酵母1087在大米淀粉废水中连续传代5次均能保持稳定。In this paper,the treatment effect on rice starch wastewater by different strains of yeast,temperature,pH,and shaking speed were studied.The results showed the Candida utilis 1087 was the most suitable strains for the treatment of rice starch wastewater.In non-sterile conditions,with 5% inoculum of the yeast,culture temperature 30 ℃,and speed of 160 rpm,the rice starch wastewater pH rose to 8.15 from an initial pH 4.0 after 24h,the CODtot reduced to 3087mg/ L from 6250mg /L,the removal rate of CODtot was reached 50.5%.The yeast strain 1087 remained stable after continuous culture five times.
