超声波促进污泥过程减量化的研究进展及展望

随着污泥处理处置问题的日益严峻,基于清洁生产理念的污泥过程减量化技术已成为业界的研究热点。超声波以其"绿色、高效"在污泥过程减量化工艺中引起了广泛关注。探讨了超声波促进污泥过程减量化的机理和主要影响因素,概述了单独利用超声波及超声波与其他技术联用促进污泥过程减量化的研究现状,展望了低强度超声波在污泥过程减量化中的应用前景和研究方向。

PROGRESS AND PROSPECT ON SLUDGE PROCESS REDUCTION BY ULTRASONIC IRRADIATION

With the increasingly severe situation of excess sludge treatment and disposal,sludge process reduction technology based on cleaning production became a highlight spot.Ultrasonic wave,which was green and efficient,was paid high attention in those sludge reduction technologies.First,the mechanism and major influence factors of ultrasound-assisted sludge process reduction were investigated.Then,the present situation of sludge process reduction by sole ultrasound,and combination of ultrasound and other technologies were summarized.In addition,the application prospect of low intensity ultrasound on sludge process reduction and a new research approach were also presented.
