Abstract
A catalyst for catalytic oxidation treatment of organic wastewater, comprising aluminum oxide, and nickel, ferrum, manganese, and cerium supported on the aluminum oxide in oxide form. Based on the weight of aluminum oxide, the contents of the following components in the catalyst are: nickel: 5.0-20 wt %; ferrum: 0.5-5.5 wt %; manganese: 0.5-3.5 wt %; and cerium: 1.5-3.0 wt %. The present invention has a good effect in catalytic oxidation for degrading COD organic pollutants in wastewater and has high reactivity.
