湿式氧化法处理废碱液的研究进展

The Study on Development of Spent Caustic Liquor Treatment by Wet Air Oxidation

石化企业产生的废碱液是一种高浓度难降解的有机废水。本文综述了湿式氧化法处理废碱液的国内外研究动态,处理效果和反应机理,指出湿式氧化法(WAO)或催化湿式氧化法(CWAO)是废碱液的有效预处理方法。由于废碱液具有浓度高、成分复杂的特性,开发出高活性,高稳定性催化剂是今后的主要研究方向之一。

Spent caustic liquor which produced by the petrolic and chemical corporation was a type of high-concentration refractory wastewater. The paper summarized thc latest studying development, treatment effects and reactive mechanism for treating spent caustic liquor by wet air oxidation （WAO） at home and abroad. Moreover, it indicated that wet air oxidation （WAO） or catalytic wet air oxidation （CWAO） was an effective method for pretreatment of spent caustic liquor. Owing to the wastewater＇s characteristic of high-concentration and complex component, exploiting catalyzes of high activity and stabilization for the wastewater treatment was one of the leading study orientations.
