为研究不同结构介质阻挡放电（DBD）在水处理中的特性，首先搭建了可实现单介质阻挡放电和双介质阻挡放电的实验平台。实验结果表明，相同实验条件下若要得到相似的放电功率，则双介质阻挡放电所需的电压远高于单介质阻挡放电；2种结构下所得的放电电压电流波形以及Lissajous图的形状均有一定的相似性，但等效电容等参数的不同使它们也存在一定的差别。然后在2种结构下以相近的放电功率，对质量浓度为100mg／L的碱性品红溶液进行了处理。通过对各自脱色率的对比分析发现，介质层数对脱色效果影响不大；通过对2种情况下的pH值和化学需氧量（COD）的对比分析说明，2种结构下发生的化学反应也是相似的，并且最终都达到了去除有机污染物的目的。通过对不同结构介质阻挡放电在水处理中的特性的实验研究和优劣分析，完善了介质阻挡放电处理污水的相关理论，可以为设计、优化介质阻挡放电水处理装置提供参考。

To research the property of different structure dielectric barrier discharge {DBD} in water treatment,we built a experimental platform that could realize single dielectric barrier discharge and double dielectric barrier discharge. The experimental results show that, to get similar discharge power under the same conditions, the required double dielectric barrier discharge voltage is far higher than single dielectric one; Because of the different parameters such as equivalent capacitance, the discharge voltage, and current waveform under two kinds of structure, the Lissajous figures also have some differences, even though they have certain similarity. In the two kinds of structures, a similar plasma power was used to process 100 mg/L of alkaline magenta solution, and a comparative analysis of the decoloring rate reveals that the number of dielectric does not affect the water treatment effect. The contrast of pH value and chemical oxygen demand （COD} reveals that the chemical reaction under two structures is similar, eventually reaching the purpose of organic pollutant removal. The experimental research and quality analysis between properties of different structure dielectric barrier discharge in water treatment show that the theory about dielectric barrier discharge of sewage treatment is improved, providing a reference for design and optimization of dielectric barrier discharge water treatment equipment.
