Municipal solid waste incineration (MSWI) fly ash is considered as a hazardous waste that requires specific treatment before disposal. The principal treatments encompass thermal treatment, stabilization/solidification, and resource recovery. To maximize environmental, social, and economic benefits, the development of low-carbon and sustainable treatment technologies for MSWI fly ash has attracted extensive interests in recent years. This paper critically reviewed the state-of-the-art treatment technologies and novel resource utilization approaches for the MSWI fly ash. Innovative technologies and future perspectives of MSWI fly ash management were highlighted. Moreover, the latest understanding of immobilization mechanisms and the use of advanced characterization technologies were elaborated to foster future design of treatment technologies and the actualization of sustainable management for MSWI fly ash.
城市固体废物焚烧（MSWI）飞灰被视为危险废物，在处置前需要进行特殊处理。主要的处理方法包括热处理、稳定/固化和资源回收。为了最大限度地提高环境、社会和经济效益，近年来，开发低碳和可持续的 MSWI 飞灰处理技术引起了广泛关注。本文批判性地回顾了 MSWI 飞灰的最新处理技术和新型资源利用方法。强调了 MSWI 飞灰管理的创新技术和未来展望。此外，详细阐述了固定化机制的最新理解和先进表征技术的应用，以促进未来处理技术的设计和 MSWI 飞灰可持续管理的实现。
