热解技术资源化处理城市污泥的研究进展

摘要

Pyrolysis,as a new kind of thermochemical treatment in the field of waste treatment,can convert the material into stable and transportable form of energy.In this article,the fundamental principle,classification and kinetics of sewage sludge pyrolysis are introduced.Characteristics,development and state-of-art of different kinds of sewage sludge pyrolysis processes are also described according to phases of their target products,along with their possible effective usages.Additionally,Hybrid pyrolysis processes and future trends of pyrolysis process in sewage sludge treatment are discussed.%热解技术作为一种新兴热化学处理技术,能将废弃物转化为稳定多用途可利用能源,二次污染小,近年来在污泥处理领域得到国内外的关注。本文介绍了污泥热解技术的基本原理,并按照热解目的产物的形态进行分类,分别从固、液、气相目的产物3个方面对相关污泥热解技术特点和产物特性进行了综述,介绍了国内外理论研究的发展概况,并对目前主要工程应用进展及相关联用工艺和新型工艺发展趋势进行讨论,同时探讨了热解技术在城市污泥处理领域下一步可能的发展方向。
