摘　　要：超声波处理可分为高频波破解处理和低频波处理,影响超声波处理技术的因素有很多,如:频率、声强或声密度、时间等。如何控制超声强度、时间等影响因素,更大效率地发挥超声波对污泥的预处理和处理作用是研究的重点。采用联合技术,充分发挥超声波技术的优势也是现今该领域研究的热点方向之一。Ultrasonic treatment can be divided into HF cracking treatment and LF processing. There are many factors that influence ultrasonic treanment, such as frequency, sound intensity or energy density of sound, time, etc. How to make full use of ultrasonic treatment on disposal of sludges by controlling intersity, time and other factors is the research focus. In order to utilize ultrasonic effectively, the integrated technique is one of the hot fields in science research.
