| 摘要: |
| 以酵母菌作为特定微生物,采用生物接触氧化工艺处理皂素生产废水，对其工艺参数进行了优选研究。结果表明，生物接触氧化工艺中以酵母菌为优势菌群，当温度为28～30 ℃，进水化学需氧量（COD）为2 710～9 200 mg/L，pH值为4.5～5.5，溶解氧为4.5 mg/L,水力停留时间（HRT）为12 h时，COD去除率超过70%, 反应出水回收的酵母干菌稳定在8.3 g/L以上，且产量随进水有机物浓度升高而上升。 |

| Study on disposal of waste water from the Diosgenin production by using yeast in bio-contact oxidation technology |
|
|
| Abstract: |
| The yeast strains were inoculated to a biological contact oxidation reactor,which was used to treat the Diosgenin production wastewater.Under the normal temperature (28-30℃)，the COD load ranges from pH 4.5-5.5，HRT=12 h,DO=4.5 mg/L,and the the removal rate was over 70%.The effluent waste water contained high concentration of yeast bodies,whose content increased with the organic concentration (COD) of the waste water. |
| Key words: yeast bio-contact oxidation technology waste water from the Diosgenin production disposal of waste water treatment |
