摘 要: 介绍了超声波调理污泥的作用机理、超声波调理对污泥结构和污泥性质(包括沉降性能、脱水性能、微生物细胞的破解效应、厌氧消化性能、活性等)的影响,阐述了超声波和絮凝剂联用、超声波和氧化剂联用、超声波和电解联用、超声波和酸碱调节联用、超声波和γ射线联用等技术在污泥调理中的应用,并针对目前存在的问题提出了今后进一步研究的思路。 The mechanisms of sludge conditioning with ultrasound and its effects on sludge structure and characters (including sedimentation property, dewatering property, microorganism cell disintegration, anaerobic digestibility, activity, etc. ) are introduced. Some combined technologies used in sludge conditioning are described, such as ultrasound-flocculant, ultrasound-oxidant, ultrasound-electrolysis, ultrasound-pH adjustment and ultrasound-γ ray, etc. The future research prospects are deduced from the present problems.
