摘要: 近年来,粉煤灰因其价格低廉、产量高,且与沸石结构相似,常被用来作为合成沸石的原材料。在水处理方面,粉煤灰基沸石处理氮磷废水的研究颇受广大学者青睐。本文简介了粉煤灰的理化性质及利用现状,概述了粉煤灰基沸石因其独特的内部结构所具有的三个特性:离子交换性、吸附性、催化性。介绍了粉煤灰基沸石除氮、磷的机理,重点论述了粉煤灰基沸石对低、中、高不同浓度的氨氮废水、含磷废水、氮磷共存废水处理的进展情况。最后分析了该领域目前存在的问题及未来发展趋势。

Abstract: In recent years, fly ash is often used as a raw material for synthetic zeolite due to its low price, high output and similar structure to zeolite. In terms of water treatment, the research on the treatment of nitrogen and phosphorus wastewater with fly ash-based zeolite is quite popular among scholars. The physical and chemical properties and utilization status of fly ash are introduced. Ion exchange, adsorption and catalysis are the main characteristics of fly ash-based zeolite, due to its unique internal structure. The mechanism of nitrogen and phosphorus removal by fly ash-based zeolite is introduced. The focus is on the progress of the treatment of low, medium and high concentrations of ammonia nitrogen wastewater, phosphorus wastewater and nitrogen-phosphorus coexisting wastewater with fly ash-based zeolite. Finally, the current problems in this field and future development trends are analyzed.

Key words: fly ash, zeolite, ammonia nitrogen wastewater, phosphorus wastewater, characteristic
