Migration patterns and control methods of heavy metals during municipal solid waste incineration
生活垃圾焚烧过程中重金属迁移规律及控制方法研究

摘要

随着城市化进程加快，生活垃圾处理问题越发突出，焚烧作为减量化、无害化与资源化重要手段被广泛采纳。但是，焚烧中重金属释放与迁移对环境、人体健康构成重要威胁。本文系统分析生活垃圾焚烧中重金属迁移方式及分布特征，基于现有研究，分析不同燃烧条件下重金属形态转化机制。同时，归纳总结当前主流重金属污染控制技术，涉及源头减量、过程调控及末端治理等方式，为提升垃圾焚烧设施环境管理水平提供依据。

Abstract

With the acceleration of urbanization, the issue of municipal solid waste (MSW) disposal has become increasingly prominent. Incineration, as a key method for waste reduction, harmlessness, and resource recovery, has been widely adopted. However, the release and migration of heavy metals during incineration pose significant threats to the environment and human health. This paper systematically analyzes the migration pathways and distribution characteristics of heavy metals in MSW incineration. Based on existing research, the mechanisms of heavy metal speciation transformation under different combustion conditions are examined. Furthermore, current mainstream heavy metal pollution control technologies are summarized, including source reduction, process optimization, and end-of-pipe treatment, providing a basis for improving the environmental management of waste incineration facilities.
