粉煤灰利用研究现状及其在环境保护中的应用

Research Status of Fly Ash Utilization and Its Application in Environmental Protection

目前,我国燃煤电厂每年产生大量的粉煤灰,这些粉煤灰一部分被回收再利用,而另一部分则被堆积且造成严重的土地资源浪费和污染问题。本文主要总结了我国粉煤灰研究现状,包括其理化性质、在我国各领域的应用方式以及环境保护方面的主要应用,探讨了粉煤灰的资源利用问题和发展前景。未来,我国应该着眼于粉煤灰的高附加值利用,并结合环境保护的主题,防止粉煤灰对环境造成污染。

At present,China’s coal-fired power plants generate a large amount of fly ash every year,part of the fly ash is recycled and reused,while the other part is piled up,causing serious waste of land resources and pollution problems.This paper mainly summarizes the current research status of fly ash in China,including its physical and chemical properties,application methods in various fields in China,and the main application of environmental protection,and discusses the use of fly ash resources and its development prospects.In the future,the use of fly ash in China should focus on the use of high added value,combined with the theme of environmental protection,to prevent fly ash from causing pollution to the environment.
