摘　　要：使用自行设计构建的高压脉冲放电催化臭氧氧化装置,首先以K-2BP为模型化合物,确定了最优操作条件,并在此操作条件下对酸性黄17、酸性黄B is和酸性黄11、4种结构相似的模拟染料废水进行实验研究,结果表明:4种染料的脱色率和COD去除率,与吸电子基团磺酸基和氯取代基相对于偶氮键的位置和数量有关。The combination of high voltage pulse discharge and ozonation as an advanced oxidation technology was used to investigate the degradation of wastewater containing azo dyes. At first, K - 2BP was selected as the model compound, the factors that affect the rate of degradation, such as discharge voltage, capacitor content, distance between discharge electrodes and pH ete, were investigated thoroughly. The optimal operation conditions were determined. On the basis of this, the effects of dye structure on degradation rate were studied. To this end, four kinds of similar - structural azo dyes, aeld yellow 4, acid yellow 11, acid yellow 17, and acid yellow Bis were used as experimental objects. The results indicated that the efficiency of decolorafion and COD removal depends on the relative position of the electron - withdrawing sulphonie group and chloride group to the azo bond, and the numbers of these electron -withdrawing groups.
