粉煤灰资源化利用研究进展

Research Progress on Resource Utilization of Fly Ash

近年来,随着能源需求量的不断增加,煤炭燃烧导致粉煤灰产生量持续攀升。粉煤灰作为工业三废之一,因其巨大的产生量、丰富的组分和独特的理化性质,有着极高的利用价值。对粉煤灰进行资源化利用,不但可以实现废物无害化处理,而且可以缓解粉煤灰堆积所带来的环境污染。本文结合粉煤灰的理化性质及其矿物相组成,综述粉煤灰资源化利用,分析目前该行业依然存在的问题,最后展望粉煤灰资源化利用的发展方向。

In recent years,with the increasing demand for energy,coal combustion has led to a continuous increase in the production of fly ash.As one of the three industrial wastes,fly ash has high utilization value due to its huge production,rich components and unique physical and chemical properties.The resource utilization of fly ash can not only realize the harmless treatment of waste,but also alleviate the environmental pollution caused by the accumulation of fly ash.Based on the physical and chemical properties and mineral phase composition of fly ash,this paper summarizes the resource utilization of fly ash,analyzes the existing problems in this industry,and finally looks forward to the development direction of resource utilization of fly ash.
