In this paper, a new technology with lower cost but more effective that treating propylene oxide wastewater with scrap iron-H₂O₂ was studied. The effects of the pH of initial reaction, the concentration of scrap iron and H₂O₂ and the reaction time on the treatment of propane wastewater were also studied. The results showed that COD_Cr removal rate could achieve 70% on the reaction conditions which the pH of early reaction was 2, the iron powder capacity 12 g · L^-1, the concentration of H₂O₂ 3.2 mL · L^-1, and the reaction time 40 min. It indicated that the cost was 3.5 Yuan to treat one ton Propylene oxide wastewater by economic analysis.
