摘　　要：针对传统方法对染料、印染行业废水处理效果不理想的现状,引入超临界水氧化法作为含染料废水的处理技术,研究了超临界水氧化处理水中活性染料雅格素藏青-R-150%的工艺条件,考察了反应温度、压力、停留时间、氧化剂用量等工艺参数对水中雅格素藏青-R-150%去除率的影响,并进行了含染料废水的动力学分析.实验结果表明,超临界水中的氧化反应能有效去除水中的COD(或TOC),在380℃,25 MPa,停留时间3.2min的条件下处理活性染料雅格素藏青-R-150%时,其COD去除率可达98.06%,本超临界氧化反应级数为1,频率因子为1.6×108,表观活化能为96.36kJ.mol-1.The conventional treatments are unable to effectively remove the chemical oxygen demand of wastewater containing dyestuff. An advanced method for wastewater containing dyestuff treatment, supercritical water oxidation（SCWO） ,was proposed. The technological process and kinetics of treating Argazol Navy- R- 150% in waste water are studied by Supercritical Water oxidation technique. The results show that Supercritical Water Oxidation is efficient for the treatment on COD（ or TOC） in waste water. With the temperature 380℃, the pressure 25MPa, the residence time 3.2 min, the removal rate of COD can achieve 98.06%. The reaction of SCWO is 1 order, the frequency factor and activation energy are 1.6×10^8 and 96.36kJ·mol^-1.
