摘　　要：以二甲苯为挥发性有机物的代表,采用微纳米气泡协同过一硫酸盐技术对二甲苯废气进行连续流动态实验研究,探讨微纳米气泡协同过一硫酸盐对二甲苯的降解作用,系统讨论二甲苯初始浓度、微纳米气泡投加量、过一硫酸盐投加量、停留时间和pH值对二甲苯降解的影响。结果表明,微纳米气泡可有效活化过一硫酸盐,微纳米气泡协同过一硫酸盐可以有效降解二甲苯;在低浓度下,喷淋液pH值对二甲苯降解率影响不大,二甲苯降解率分别随微纳米气泡投加量、过一硫酸盐投加量和停留时间的增加而升高。Experimental studies were conducted to investigate the synergistic effect of micro-nano bubbles and persulfate on the degradation of xylene.The effects of initial xylene concentration,dosage of micro-nano bubbles,dosage of persulfate,retention time,and pH value on xylene degradation were systematically discussed.The results showed that micro-nano bubbles effectively activated persulfate,and the combination of micro-nano bubbles and persulfate could efficiently degrade xylene.At low concentrations,the pH value of the spraying solution had little influence on xylene degradation,while xylene degradation increased with increasing dosage of micro-nano bubbles,persulfate,and retention time.
