Abstract: This paper mainly introduces the pyrolysis process of sewage sludge and pyrolysis mechanism，and summarizes the structural properties of the solid residue：pore structure distribution，elemental composition and acidity. The progress of the applications of the solid residue in adsorbing metal ions，dye or COD in waste water and H2S or SO2 in gas flow is introduced. It is emphasized that the pyrolysis of sewage sludge will play a very important role in its reuse.

摘要： 对国内外污泥热解工艺和热解机理进行了综述，从元素组成、孔结构分布和酸度3个方面总结了热解残渣的结构特点，介绍了其作为吸附剂用于吸附水中的金属离子、染料、COD及气流中的SO2和H2S等的研究进展，指出热解工艺是污泥资源化很有发展前景的一种处理方法。
