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.
