The application of ultrasonic technology in the treatment of organic pollutants in water has attracted more and more attention in recent years. Compared with conventional treatment, ultrasonic treatment is more efficient and time saving. Ultrasonic technology is effective for the degradation of many refractory organic pollutants. In this paper, the principle, influencing factors and various methods of ultrasonic degradation of organic pollutants are studied in view of ultrasonic treatment alone, ultrasound treatment methods combined with biocatalysts, chemical oxidation and adsorption techniques, respectively. In addition, the problems existing in the treatment of organic pollutants in water by ultrasonic technology are analyzed and the development direction is put forward.
近年来，超声技术在水中有机污染物处理中的应用越来越受到关注。与传统处理方法相比，超声处理更高效、更省时。超声技术对许多难降解有机污染物的降解具有有效性。本文分别针对单独超声处理、超声与生物催化剂、化学氧化及吸附技术相结合的超声处理方法，研究了超声降解有机污染物的原理、影响因素及各种方法。此外，分析了超声技术处理水中有机污染物存在的问题并提出了发展方向。
