Ultrasound treatment of waste paper fibers enlarges the applicable fields of this kind of fibrous material. This paper reviewed the applications of ultrasonic treatment of waste paper fibers in improving the properties of recycled paper, intensifying the production of fermentable sugar and ethanol, assisting the preparation of cellulose nanofibers, and enhancing the durability of cement building materials. The influence factors of ultrasonic treatment such as power and frequency of ultrasonic, action time of ultrasonic, temperature and suspended sediment concentration were analyzed, and the influence of ultrasonic treatment on the crystalline property, chemical structure and reaction accessibility of cellulose were summarized. Finally, the existing problems were analyzed and the future research and development direction were prospected.

Key words: ultrasonic treatment, waste paper fibers, cavitation
