摘　　要：基于电化学原理描述了双电层电容的产生及其影响,通过采用电化学阻抗谱方法和测量阶跃响应曲线并进行参数拟合的方法,建立了电解槽负载的等效电路模型。在该模型基础上,通过仿真和实验详细分析了双电层电容的大小与脉冲参数(频率、占空比等)的关系。结合电化学知识,给出脉冲电凝聚法印染污水处理的应用场合,脉冲电源参数选取的方法和原则,最后通过实验验证了该选取方法的合理性和有效性。Based on the basic electrochemical theory, the existence and effects of the double layer capacitor are described. The equivalent circuit model of electrobath is obtained by the methods of electrochemical impedance spectroscopy （EIS） and curve fitting. Furthermore, the relationships between the double layer capacitor and the parameters of the voltage pulse are investigated, including the frequency and duty cycle, etc. The basic principle is obtained on how to choose the appropriate power parameters in the application of dye wastewater treatment under a pulsed power supply. Experimental results validate the rationality of this method.
