脉冲放电过程在产生放电等离子体的同时，产生高能电子、紫外光．O3等多因素，可综合作用于水中或大气中的污染物。本文把脉冲放电等离子体和TiO2光催化相结合，对我们设计的喷嘴一筒式反应器中的喷嘴放电极进行二氧化钛镀膜，利用脉冲放电过程中的紫外光实现对二氧化钛的催化．增加放电过程以羟基为主的活性自由基的数量。以偶氮类染料酸性橙Ⅱ为研究对象，对比了放电极二氧化钛镀膜对放电等离子体技术对污染物降解效率的影响。研究了镀膜前后分别脉冲峰值电压，溶液初始浓度、溶液pH值、电导率等因素对偶氮类染料酸性橙Ⅱ液降解率的影响。

The pulse discharge system produce discharge plasma and the high-energy electron, ultraviolet light, ozone etc, can be comprehensively dealt with water or atmospheric pollutants. In this paper, pulse discharge system combined with TiO2 photocatalysis, by designing nozzle-electrode of nozzle-cylinder reactor with coating of TiO2. With using ultraviolet of pulse discharge process to achieve catalytic of TiO2, for increaseing the active radicals quantity of primarily hydroxyl, The paper studied the azo-dye Orange Ⅱ to compare with coating of TiO2 electrode on degradation rate of pollutants. The main research is about degradation rate of acid orange Ⅱ in respectively with before and after coating on pulse peak voltage, pulse repetition frequency, discharge electrode diameter, initial concentration of solution and other factors.
