Abstract
A method for treating waste water containing carbonyl iron is provided, which relates to a method for treating the waste water containing carbonyl iron which is generated during the production process of carbonylation metallurgy. The invention is characterized in that the treatment process comprises adding hydrogen peroxide as oxidant into the waste water containing carbonyl iron to oxidize the carbonyl iron in the waste water into solid iron oxide, thereby realizing disinfection treatment to the waste water containing the carbonyl iron and recycling valuable iron metal in the waste water. The method for treating the waste water containing carbonyl iron of the invention adopts 30%-50% of hydrogen peroxide to perform a redox reaction with the carbonyl iron in the waste water so as to perform a disinfection treatment to the waste water and enable the waste water to realize standard discharge as well as reclaim the valuable metal in residues. Compared with the traditional technology, the invention has good disinfection effect and no pollutant during the treatment process and is environment friendly. The reaction product is solid iron oxide which is mainly Fe2O3 and can be recycled after being cleaned.
