摘要: 研究了不同初始pH值对催化湿法氧化降解垃圾渗滤液总有机碳(TOC)去除率的影响及其原因, 分析了催化剂溶解与反应液pH值变化的对应关系, 并利用Elovich方程描述了降解反应的动力学过程, 建立了速率常数k值与初始pH值之间的关系.

关键词: pH值, 催化湿法氧化, 垃圾渗滤液, 污水处理

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
