摘　　要：污水处理过程中会产生大量的污泥,剩余污泥的处理与处置已经成为污水处理厂面临的重大挑战,而污泥减量就是从源头上减少污泥的产生。文章阐述了超声波破解污泥的作用机理和影响因素,分析了超声波对污泥粒径、脱水性能和厌氧消化的影响,初步探讨了超声波技术与碱处理、臭氧法、AB法技术的联合,列举了目前应用超声波技术处理污泥的工艺实例,展望了超声波污泥减量化技术的应用前景。The treatment and disposal of excess sludge is becoming a rising challenge for wastewater treatment plants due to huge amounts of sludge production, and reducing sludge from source is an effective method. The paper describes the mechanism and influencing factors of sludge cracking by ultrasonic wave, and analyzes the effects ultrasonic wave on sludge particle size, dewatering performance and anaerobic digestion. In addition, the paper preliminarily investigates the combination of ultrasonic technology with alkali treatment, ozone and AB technology, lists current applications of ultrasonic technology to sludge treatment process, and prospects the future of ultrasonic sludge reduction technology apphcation.
