摘　　要：随着全球经济的增长、人口的增加、资源的不断消耗,如何充分利用剩余污泥资源,使其变废为宝已成为当今世界环境保护领域的热点议题。污泥不再作为无用的废物经简单处理后丢弃,而是通过消化、堆肥、焚烧、热干化等方式处理后,尽可能使之成为可以循环利用的有效资源。以全球8个典型地区为例,阐述了各地区对污泥的管理政策、处置方法和处理技术,并介绍了不同国家和地区对剩余污泥处置的可持续发展观点和实践过程。在综合了各地区的经验后指出,消化→焚烧→灰分利用将是未来污泥处理/处置技术与管理的终极发展目标。With the global economic development, population increase and resource decrease, how to make excess sludge become a useful resource has become a global environmental topic. Sludge is never considered as a useless waste, and it can be used as an effective resource if appropriate treatment/disposal approaches are applied, such as digestion, composting, incineration, thermal drying and so on. The policies and technical approaches for sludge treatment/disposal in the global eight typical regions were expounded. The sustainable development viewpoint and practice for excess sludge disposal in different countries and regions were introduced. Based on the review, an ultimate development objective of future sludge treatment/disposal is put forward： digestion→incineration→ash utilization.
