摘　　要：通过生物吸附处理酵母富硒生产废水中的主要毒害污染物硒,使酵母富硒生产废水中残留的无机硒浓度从150 mg/L降至12 mg/L。通过摇瓶实验,将处理后的酵母富硒生产废水,部分替代酵母发酵培养基配制水进行重新利用。结果显示,经处理废水替代酵母发酵培养基配制用水的比例可达60%~80%。处理后的酵母富硒生产废水回用于酵母发酵工艺具有可行性。The main toxic pollutant selenium in selenium-enriched yeast production wastewater is treated by biosorption,and the residual inorganic selenium concentration in selenium-enriched yeast production wastewater is reduced from 150 mg/L to 12 mg/L.Through shake flask experiments,the treated yeast selenium-enriched production wastewater is reused by partially replacing the water prepared by yeast fermentation medium.The results show that the proportion of treated wastewater replacing yeast fermentation medium with water can reach 60%~80%.It is feasible to reuse the treated selenium-enriched yeast production wastewater for yeast fermentation process.
