In this study, the landfill leachate was treated by Catalytic wet air oxidation, and the heterogeneous catalyst Fe-Co-Ru-Ce/γ-Al 2 O 3 was prepared. The calcination temperatures were respectively set at 300, 450, 600, 750 and 900 °C, and the Fe-Co-Ru-Ce/γ-Al 2 O 3 impregnated with the four metal salt solutions was calcined at the set temperature for 3 h to study the effect of calcination temperature on the activity of the catalyst.The results showed that when the calcination temperature was 450 °C, the activity of the catalyst reached the maximum. At this time, the COD removal rate, decolorization rate and turbidity removal rate of the treated water samples were the highest, which were 78.1%, 60.4% and 92.7%, respectively.
