摘要
伴随着城市化进程加快与工业迅速发展，产量日益增加的污泥已对城市生态环境造成极其严重的威胁。为了有效地消除这种环境卫生公害，并且促进其资源化，提出了采用超声波技术进行污泥处理之建议，在总结国内外相关研究现状的基础上归纳出该技术的三大主要优势：杀菌、除臭、提高污泥稳定性；污泥减量效果显著；促进污泥中氮、磷量的增加，有利于污泥资源化；改善污泥絮凝脱水性能。最后指出了目前国内该技术所急需解决的问题，以明确今后的研究方向与重点。
Abstract
With the quick urbanization and development of industry,the ecology and environment in cities are subjected to the extremely serious threat leaded by the more and more increasing production of sludge. In order to effectively eliminate such environmental pollution as the sludge, and promote its utilization, an advice of application of ultrasound technique in sludge treatment is put forward. Based on the present status about domestic and foreign study of ultrasonic treatment of sludge,three main advantages of ultrasound technique are concluded,such as disinfect pathogens, deodorizing, sludge stabilization improving and remarkable dewatering,increase of the nitrogen and phosphorus content in sludge for its much better utilization. In addition, the present problems needed to be solved urgently for this technique in our country are pointed out,as the directions and keys for the further study of ultrasonic treatment of sludge.
