| 摘 要： | 对应用酵母菌和光合细菌综合处理皂素废水进行了初步研究,结果表明,第一步用产朊假丝酵母处理后,COD cr去除率为34.77%,出水pH为6.87;第二步用光合细菌处理后,COD cr去除率为87.2%,总去除率达91.2%,出水pH为8.6,NH4 -N总去除率达96.7%,SO42-浓度基本无变化。该处理方法具有运行动力消耗少,降解效率高,且便于资源化等优点。

| Abstract: | A preliminary study on diosgenin wastewater treadment by the combination of photosynthetic bacteria(PSB) and Candida utilis has been carried out.The results demonstrated that the CODcr deduction rate was 34.77% and the outflow pH was 6.87 while firstly treated with Candida utilis.A CODcr deduction rate at 87.2% was observed following the second treatment with PSB and the total CODcr deduction rate was shown to be 91.2%.Its outflow pH was 8.6.Also the removal percentage of the total NH_4~ -N was up to 96.7% and the concentration of the SO_4~(2-) had no change nearly.The merit of treatment includes low power,high degradeation and easy to resource and so on. |
