Abstract Fly ash is a kind of fine particulate solid waste. Inappropriate disposal of fly ash will damage the environment and affect human health. The production of zeolite from fly ash is a high value utilization way, which not only solved the disposal problem of fly ash, but also provided a new environmental protection material with the concept of "treating waste by waste". In this paper, the characteristics of fly ash and zeolite and the synthetic methods of zeolite from fly ash are briefly reviewed by summarizing the relevant literatures in the recent years. The modification methods of zeolite derived by fly ash, such as cationic surfactant modification, ion exchange modification and magnetic modification have been focused on this review. The application of modified zeolite acting as adsorbent, and catalyst carrier for water treatment is also summarized. Suggestions on modification of zeolite from fly ash and its application in sub-water treatment are put forward.
