Abstract:
An experiment was made on the pharmaceutical wastewater treatment with the contact oxidation process by adding effective microorganisms(EM) to remove the chemical oxygen demand(COD). The results show that when the inoculation of EM(VEM ∶ VPW) is within 1 × 10-4 - 3 × 10-3, the reduction rate of COD reaches as high as 13.4%. The EM adding period is about 10 days, and EM can be applied to the pharmaceutical wastewater treatment.

摘要：
应用生物接触氧化法投加有效微生物菌群(EM)对制药废水中化学需氧量的去除效果进行试验研究和分析。结果表明:EM接种量(VEM∶VPW)在1×10-4~3×10-3范围内，化学需氧量去除率最大增幅达13.4%;EM投加周期约10d左右，在工程应用上具有可行性。
