摘要
阐述了污泥的超声脱水及降解机理,强调了絮凝剂对污泥脱水的重要作用,重点介绍了超声技术在污泥脱水中的研究现状及影响因素包括:频率、声强、功率、反应器的设计与换能器类型、污泥自身因素等进行分析,最后提出了发展方向。
The mechanisms on ultrasonic dehydration and decomposition of sludge are discussed. It is important to use flocculants in sludge dehydration. The ultrasonic techniques applied in sludge dehydration and the effective factors （including ultrasonic frequency, intensity, power, reactor, ultrasonic transducer, characters of sludge ） are analyzed. The developmental direction of ultrasonic dehydration is discussed.
