Abstract：This paper introduces several technologies of treating the solid waste dust mud at home and abroad， focusing on the rotary kiln process and the rotary hearth furnace process in the fire treatment process， and also emphatically introduces the technological processes and technical characteristics of the treatment processes of the sintering machine ash， the converter ash and the zinc-bearing dust slime such as blast furnace ash in recent years. With the change of solid waste sludge composition from 2010 to 2018， the practice and experience of the converter bottom furnace in treating the zinc containing dust mud are introduced， especially after 2017， a large amount of scrap steel is added to converter and the content of zinc in converter ash is greatly increased， in order to maximize the benefit and realize the zero discharge of the zinc containing dust， the rotary hearth furnace has made beneficial practices and attempts in dealing with the zinc dust and mud. Some suggestions for treating solid waste sludge in steel plant are also given， which can provide a reference for domestic counterparts.
