Abstract

Abstract: The effect of initial pH values on the degradation efficiency of the landfill leachates by catalytic wet air oxidation(CWAO) was studied and the relationship between pH value and the dissolution of the catalyst was investigated. Meanwhile, the ki netic process of the decomposition is described with Elovich equation, and the corre ction relationship is also described between initial pH value and the removal rate of the dissolution of the landfill leachates used.

Key words: pH value, catalytic wet air oxidation, landfill leachates, sewerage treatment
