- Abstract:
- A pharmaceutical company produces active pharmaceutical ingredients (APIs) for antibiotic through chemical synthesis. Its wastewater contains high organic matter and is difficult to biodegrade. The original treatment process whose effluent quality cannot meet the discharge standards was improved according to the characteristics of wastewater. The high-concentration wastewater is pretreated by the combined process of iron-carbon micro-electrolysis, Fenton, coagulation sedimentation, and then mixed with the comprehensive wastewater into the biochemical treatment section. The operating results show that the treatment system has good degradation performance for antibiotic wastewater. The COD removal rate in the pretreatment section reached 50.23%, the removal rate of COD in the biochemical section reached 94.2%, and the average removal rate of NH3-N was above 79%. The effluent quality meets the influent standards of the sewage plant in the industrial park.
