摘　　要：分析了微米气泡(MB)和纳米气泡(NB)的基本性质,考察了臭氧耦合微气泡对苯酚废水的处理效果,探究了苯酚降解的一级动力学及中间产物情况。结果表明:NB的稳定性比MB更好,Zeta电位变化幅度较低。反应60 min时,臭氧微米气泡(O_(3)/MB)和O_(3)/NB对苯酚去除率为75.6%和94.7%,COD去除率分别达到25.6%和42.7%,一级反应速率常数分别为0.35,0.65 h^(-1),表明O_(3)/NB系统对苯酚废水的降解效果更好。O_(3)/NB系统具有更强的直接氧化能力和更高的·OH产生速率。紫外-可见吸收光谱分析证实苯酚降解过程中产生了醌类化合物等中间产物。The basic properties of micrometer bubbles(MB)and nanobubbles(NB)were analyzed,and the effect of ozone-coupled microbubbles on the treatment of phenol wastewater was examined to investigate the first-order kinetics of phenol degradation and the intermediate products.The results showed that NB had better stability and lower Zeta potential variation than MB.At 60 min of reaction,the removal rate of phenol by ozone micrometer bubbles(O_(3)/MB)and O_(3)/NB were 75.6%and 94.7%,and COD removal rate reached 25.6%and 42.7%,respectively,the first-stage reaction rate constants were 0.35,0.65 h^(-1),which indicated that the O_(3)/NB system was more effective in the degradation of phenol wastewater.The O_(3)/NB system has greater direct oxidation capacity and higher·OH production rate.The UV-Vis absorption spectroscopy analysis confirmed that intermediate products such as quinones were produced during phenol degradation.
