ABSTRACT

Experimental use of catalytic wet air oxidation of landfill leachates treatment simulation, catalyst preparation by impregnation method of Cu, Fe, Co as a catalyst active component, La, Ce for the catalytic agent. Experiments were conducted to comprehensively assess the activity and stability of a catalyst developed with varying component ratios of composite supported catalysts. Various parameters including water pH, decolorization rate, COD removal, as well as the detection rates of Cu2+ and Fe3+ dissolution, were evaluated. Based on the experimental results: Choose Fe-Co=3:3 as the best catalyst, Ce is the best catalytic additives. Based on this premise, research was conducted on the active component Pt, utilizing the Fe-Co-Ru-Pt-Ce/FSC composite catalyst support. The ratio Fe-Co-Ru-Pt-Ce =0.75:0.75:0.75:0.75:3 was determined as the optimal ratio for the catalyst. Modern testing technology, such as atomic absorption, is utilized to determine the performance of catalysts in testing. Through many experiments, from the treatment effect and the stability of both the comprehensive analysis of the catalyst, to determine the best catalyst agent is Ce. Under the same conditions dealt with landfill leachates, reaction time conditions for 90min, landfill leachates processing wastewater. The turbidity removal rates of Fe Co catalyst and Cu Ce catalyst reached 93.8 % and 94.4 %, respectively.
