| 摘 要： | 超声-微电解是近年来发展起来的一项水处理复合技术,此法借助超声波的空化效应、自由基作用和机械作用强化微电解反应。超声空化效应产生的空化泡在溃陷的瞬间形成高温高压,不仅有利于铁屑表面的传质作用,还引发了自由基反应,空化效应产生的微射流和冲击波促使电极表面不断更新,同时使反应液与铁屑、活性炭充分混合接触,有效的促进了原电池反应的快速进行,实现超声和微电解对工业废水中有机污染物的协同降解,提高对废水有机污染物的降解效率。

| Abstract: | Sono-Microelectrolysis degradation of non-degradable organic pollutants in wastewater is a newly developed composit technology of wastewater treatment.In this process,the efficiency of micro-electrolysis is promoted by ultrasonic cavitation,free radical and mechanical effect.High pressure and temperature will be formed when the cavitation bubbles collapse in the moments,it is not only conducive to the mass transfer of the iron surface,but also lead to free radical reaction.Mechanical effect promotes the electrode surface continuously updated,at the same time,the reaction system is fully mixed by the effect.Thus synergetic degradation of non-degradable organic pollutants is achieved and the efficiency is increased. |
