发布时间：2019-03-15 09:25
【摘要】：粉煤灰作为燃煤电厂排出的大量固体废物,其处理和利用问题在全球范围内引起了人们的广泛关注。粉煤灰作为一种资源在世界范围内已成为共识,国内外已有大量的研究表明粉煤灰在土壤改良修复方面具有巨大的应用潜力。分析粉煤灰的组成结构与理化特性;阐述粉煤灰改良和修复土壤的机理及其对不同类型土壤改良及修复的应用,包括对矿区土壤、盐碱化土壤、沙化土壤、耕地土壤等的改良及修复技术;最后分析并总结了粉煤灰目前在土壤改良及修复过程中存在的主要问题,提出粉煤灰在农业领域利用的新模式。
[Abstract]:As a large amount of solid waste discharged from coal-fired power plants, the treatment and utilization of fly ash has attracted wide attention all over the world. Fly ash as a resource has become a consensus in the world. There have been a large number of studies at home and abroad to show that fly ash has great application potential in the field of soil improvement and remediation. The composition structure and physical and chemical properties of fly ash were analyzed. This paper expounds the mechanism of improving and repairing soil with fly ash and its application to different types of soil, including mining area soil, salinized soil, sandy soil, cultivated soil and so on. Finally, the main problems existing in the process of soil improvement and remediation of fly ash are analyzed and summarized, and a new model of fly ash utilization in agricultural field is put forward.
