摘要：
抗生素废水由于有机物含量高、含有较多残留的抗生素，常规的处理方法很难达到处理要求。从处理抗生素废水的活性污泥中分别分离出3 株光合细菌、酵母菌、放线菌，通过比较处理效果，确定后续试验的菌种。最后，通过菌种单因素试验、菌种复配试验、复合菌种配比正交试验，确定了复合菌种的最佳配比：光合细菌、酵母菌和放线菌投加量分别为10、6、2 g/L。此时COD 去除率可以达到60.48%。

Abstract:
Since antibiotic wastewater contains plenty of organic substances and some residual antibiotics,traditional treatments could hardly meet the treatment requirements.It is studied that 3 strains of photosynthetic bacteria,yeasts and actinomycetes have been isolated from activated sludge which is used for treating antibiotic wastewater.By comparing the treatment efficiency,it is ascertained that subsequent strains.Then,single-factor experiment,bacterium complexing experiment and orthogonal experiment of compound bacteria ratio are done to determine the best ratio of compound bacteria.The result indicates that when the amount of photosynthetic bacteria,yeasts and actinomycetes are 10,6 and 2 g/L,respectively,the best COD removing rate reaches 60.48%.
