微纳米气泡强化臭氧氧化降解含酚废水
Micro-nano bubbles enhance ozone oxidation and degradation of wastewater containing phenol
摘要
Abstract
In order to degrade the highly toxic phenol-containing industrial wastewater,this paper combined micro-nano bubbles with ozone oxidation to investigate the effects of treatment temperature,solution pH,initial phenol concentration and ozone concentration on phenol degradation.The results showed that the rupture of micro-nanobubbles could induce the generation of more·OH,which could make up for the shortcomings of low mass transfer efficiency and insufficient oxidizability of ozone,so that the redox potential of the reaction system could be significantly increased and played a major role in phenol degradation.Compared with ozone oxidation,the phenol degradation effect was significantly improved.The increase of ozone concentration,the increase of solution pH and the decrease of initial phenol concentration could promote the generation of more·OH in the reaction system,which could enhance the phenol removal rate.The intermediate products of phenol degradation were detected by gas chromatography-mass spectrometry(GC-MS),and the possible pathways of phenol degradation were speculated.Overall,the combination of micro-nano bubbles with ozone oxidation was a potential phenol removal technology,and the results of this study were of great significance in guiding the application and popularization of this technology in the degradation of industrial wastewater.关键词
