Abstract
In this study, the wet oxidation treatment of pharmaceutical sludge was investigated. The effects of the reaction parameters on the removal rate of volatile suspended solids (VSS) and the total chemical oxygen demand (COD) were discussed. The results illustrated that the highest could reach up to 68.9% and 93.7% separately under 260 °C with initial oxygen pressure 1.5 MPa and the reaction time 60 min. The addition of Cu2+ could increased the COD removal rate significantly. The results demonstrated that wet oxidation showed promising as an economical and feasible alternative for the pharmaceutical sludge treatment.
