摘 要: 本文阐述了超声波用于树脂再生的最新技术,超声脱附以及它的原理—超声场聚能效应。该方法和传统的化学方法相比较:不仅具有操作简单,化学药品消耗少,排污量少等优点。而且还能增加树脂的脱附速率,减少脱附时间,增加解吸平衡物的浓度。本文综述了在这一领域的最近研究进展,各种不同频率和功率对树脂再生效果的影响,为该领域的研究工作提供参考。 This paper reviews the new technology of the resin regeneration with ultrasonic wave, i.e., ultrasound desorption and its principle, 'ultrasound field spot elfect'. Compared with the traditional chemistry method, this technology possesses the advantages of easier operation, lesser chemical consume and fewer wastewater drainage.Meanwhile, it can enhance the rate of polymeric resin desorption and increases the concentration of desorbed solute. This paper also discusses the effects of ultrasonic frequency and power on the process.
