典型固体废物中冶金微生物及其浸出机理研究进展

Microorganisms used for bioleaching of metals from typical solid wastes and their leaching mechanism: a review

摘要:

典型固体废物(废电器、废电池、污泥、焚烧飞灰、废催化剂等)含有大量金属资源,回收再利用的价值极高。微生物浸出典型固体废物受多因素影响。对不同微生物浸出金属的菌种筛选、浸出规律和机理的掌握,有助于典型固体废物中金属资源的绿色高效回收,可为我国"双碳"目标作出贡献。本文综述了从典型固体废物中浸出金属的各类微生物,分析了冶金微生物的作用机制,并展望了微生物冶金的应用前景,以期为微生物冶金技术在典型固体废物中的高效应用提供理论参考。

Abstract:

Typical solid wastes contain many metal resources, which are worthy of recycling. The bioleaching of typical solid waste is affected by multiple factors. Green and efficient recovery of metals based on the characterization of leaching microorganisms and the elucidation of leaching mechanisms may contribute to the implementation of China's "dual carbon" strategic goals. This paper reviews various types of microorganisms used for leaching metals from typical solid wastes, analyzes the action mechanism of metallurgical microorganisms, and prospects the application of metallurgical microorganisms to facilitate the application of metallurgical microorganisms in typical solid wastes.
