文章导读

摘要粉煤灰是一种细小的颗粒固体废弃物,处理不当会造成环境危害且影响人类健康。利用粉煤灰生产沸石是一种高值化利用方式,既解决了一部分粉煤灰处置问题,同时也增加了一种新型"以废治废"的环保材料。通过对近年来有关粉煤灰沸石的相关文献进行总结梳理,简述了粉煤灰与沸石的特征及粉煤灰沸石的合成方法,重点介绍了粉煤灰沸石的几种改性方法及其机理,如阳离子表面活性剂改性、离子交换改性和磁改性等。同时介绍了粉煤灰沸石作为吸附剂、催化剂载体在水处理中的应用,并对粉煤灰沸石改性及其在水处理中应用的发展方向提出了建议。

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.

Keywords： fly ash zeolite organic modification inorganic modification magnetic modification wastewater treatment
