双脉冲放电等离子体水处理技术是一种有效的水处理方法,利用产生的活性物种能高效降解多种有机大分子污染物。针对复杂混合体等离子体反应器中气相O3生成情况进行了研究,重点考察了脉冲电压、曝入气体体积流量、不同的填料特性(粒径和表面粗糙度)等条件对水处理时生成O3的影响。实验结果表明,生成O3质量浓度随着放电电压增加而增大,随着曝入气体体积流量的减小而增加。填入不同粒径的填料生成O3质量浓度也有所不同,其中填充粒径9mm的填料时O3质量浓度最大。另外,粒径相同,但表面峰密度大的填料在生成O3时也表现出更好的特性。
Double pulse discharge plasma water treatment technology is an effective water treatment method, the use of active species generated can efficiently degrade a variety of organic macromolecule pollutants. Aiming at the formation of gas phase O3 in a complex hybrid plasma reactor, the effects of pulse voltage, gas volume flow, different filler characteristics (particle size and surface roughness) on the formation of O3 influences. The experimental results show that the mass concentration of O3 increases with the increase of the discharge voltage and increases with the decrease of the volume of the aerated gas. Fill into different particle size of the filler O3 mass concentration is also different, which filled with filler 9mm diameter O3 mass concentration maximum. In addition, fillers with the same particle size but high surface peak densities also exhibit better properties in the generation of O3.
