摘要

为了考察气相脉冲放电时水中H2O2生成规律，采用针-板式反应器，进行了实验，研究放电电压、气体流速、电极间距以及pH值对水中H2O2生成的影响.实验结果表明：提高放电电压，能够促进水中H2O2的生成；当气体流速为1.6 L/min时，水中H2O2浓度最大；减小电极间距，电场强度增大，有利于H2O2的生成；酸性条件时水中H2O2浓度较大.

Abstract

Low temperature plasma technology can be used to treat the refractory biodegradable organic compound. There are many strong oxidizing active species (such as H2O2

·OH

O3) in the plasma channel when voltage discharge is high. A needle-plate reactor was used to investigate the generation of H2O2 in the pulsed discharge system. The effects of different experimental conditions on H2O2 generation

such as discharge voltage

gas flow rate

electrode gap and pH value

were studied. Experimental results show that as discharge voltage increases

the concentration of H2O2 in water increases; when the gas flow rate is 1.6 L/min

the concentration of H2O2 is the highest in water. The electric intensity increases as the electrodes gap decreases

and thus the东concentration of H2O2 increases.
