中文摘要：

采用低温等离子体技术，在自行设计的双通道放电等离子体装置中，对模拟酸性紫红染料废水进行了降解研究。考察了电极距液面间距、液层厚度、初始浓度、pH等因素对酸性紫红废水脱色率的影响。结果显示，电极距液面间距越小，废水脱色率越高；随着液层厚度的增大，相同时间下脱色率降低；随着初始浓度的增大，在相同放电时间下脱色率降低，随着时间的延长，不同浓度的染料废水脱色率都可达到90％以上；pH对脱色率的影响不大。结论表明自行设计的双通道放电等离子体装置对模拟酸性紫红染料废水的脱色率高，同时具有处理时间短、对废水的操作条件较宽、不受pH的限制等优势。

英文摘要：

The degradation of Acid red B waste water was studied with low temperature plasma technology in a self-designed plasma device which could discharge with dual channel. The effect on decoloration rate of Acid red B solution by various influencing factors such as the distance between electrode and the liquid, thickness of liquid layer, pH value and solution initial concentration was studied. It is demonstrated that the decoloration rate increases with cutting the distance between electrode and the liquid down; the decoloration rate decreased with increasing of thickness of liquid layer and concentration for the same discharge time, and the decoloration rate could be up to 90% with the time prolonged; the pH value has a little effect on the decorolation rate; The results show that the self-designed plasma device has advantages of high decoloration rate for the Acid red B waste water, short-time processing, wide range of operating conditions and no limitation of the pH value.
