摘要

This study evaluates the application of wet oxidation for the treatment of oily sludge by using hydrogen peroxide as oxidant instead of air at high temperature in a batch reactor. The experimental results show that the quantity of oxidant with 250%to theoretical oxygen demand of oily sludge is comparatively effective and economica1. Adding a catalyst, Fe³⁺, significantly improved the COD removal. Reaction mechanism for WO of oily sludge is analyzed. Oxidation of intermediate for oily sludge is a rate-limiting step for further oxidation of oily sludge.
