摘　　要：以酸性红染料水溶液为模拟废水,考察了污染物初始浓度、电流、电压和溶液体积等实验参数对酸性红染料辉光放电等离子体降解的影响。实验用辉光放电等离子体技术对酸性红AR73的降解进行了研究,借助紫外分光光度法来分析分解过程中的酸性红染料浓度的变化。在不同电压、电流的条件下,分解速率随电压电流增大而加快;调节pH后研究了酸碱性对染料废液的处理效果;通过添加一些在其他有机废水处理中有效果的催化剂TiO_2和Fe^(3+)研究其对酸性红的催化效果。The non-pulsed DC glow discharge plasma technology has been widely applied in recalcitrant organic wastewater processing, due to its high efficiency and no secondary pollution characteristics. The experiment uses glow discharge plasma degradation of Acid Red AR73 with UV spectro photometry to analyze changes in the process of decomposition of acid red dye concentration. It is found that the rate of decomposition increases as the voltage and current accelerate. The paper also deals with non-liquid waste treatment effect by adjusting the pH of acid-base dye, and studies the catalytic effect of acid red by adding other organic wastewater treatment catalyst TiO2 and Fe3＋
