doi:10.16552/j.cnki.issn1001-1625.2025.0004

Abstract

Abstract: Heavy metal elements in industrial solid waste have the characteristics of various types, obvious regional characteristics, variable valence toxicity, various forms of migration and transformation, and unstable state. The leaching of heavy metal ions is a key problem restricting the resource utilization of industrial solid waste. In this paper, the leaching methods and leaching mechanisms of heavy metal ions in main industrial solid wastes at home and abroad are reviewed, and their advantages and disadvantages are compared. The solidification/stabilization methods and their mechanism of action commonly used in remediation of heavy metal pollution are mainly introduced. The main factors affecting the solidification/stabilization of heavy metal ions are reviewed. Finally, the detection and solidification/stabilization of heavy metals in industrial solid wastes are prospected. It is expected to provide reference for exploring the leaching behavior of heavy metal ions and the characteristics and mechanism of solidification/stabilization, and provide reference for realizing the efficient and safe resource utilization of industrial solid wastes.

Key words: industrial solid waste, heavy metal, leaching, solidification, stabilization
