摘要
将催化湿式氧化技术应用于垃圾渗滤液中有机物的降解,着重研究了氧化剂(以氧分压表征)对降解效果的影响.结果表明:氧化剂是影响垃圾渗滤液中有机物降解反应的重要因素之一,随着氧分压的增大,催化氧化反应速率逐渐增加,其降解过程符合Allometric方程(Y=aXb),但随着氧分压的增大,催化氧化反应速率增加的幅度逐渐减小,并分析了其原因.
Catalytic wet air oxidation(CWAO) was employed to reduce the organic compounds in the landfill leachate and the influence of oxidant (characterized by oxygen partial pressure) on the degradation was investigated. The results indicate that the oxidant is an important factor in treating leachate by CWAO and decomposition rate of the organic (pollutants) increases with the rise of oxygen partial pressure, but the influence of (oxidant) on the decomposition rate decreases gradually with the increase of oxygen partial pressure. The dynamics course of the organic (compounds) degradation could be described with the Allometric equation(Y=aX^b), and the mechanisms (analyses) were given.
