粉煤灰的应用研究进展

文章简要介绍了粉煤灰的结构和性质,分析了目前我国粉煤灰的生产现状以及对环境造成的危害,阐述了粉煤灰在多领域的应用途径。粉煤灰不仅在造纸废水、重金属污染、城市污水、洗煤废水等污废水处理方面有广泛的应用价值,它还作为一种掺和剂在改善建筑制品、水泥、混凝土等建材性能方面起到重大作用,同时粉煤灰还可以作为原料合成性能良好的A型沸石分子筛,在农业上可以作为优良的土壤改良剂。文章对粉煤灰的应用前景进行了展望。

Advance Research on the Application of Fly Ash

The article firstly introduced the particular structure and properties of fly ash. The current production situation and impact on the environment of fly ash were also analysed. Fly ash was widely used within many fields, and the application achievements were very effective, such as the treatment for SOlne dirty wastcwater in paper-making, heavy-metal contamination, municipal sewage, coal washing. Building materials processing also applied fly ash to improve pertbrmances when producing building products, cement and concrete. Fly ash was also the raw materials for the synthesis of zeolite molecular sieve and agricultural fcrtilizer. Development prospect on the application of fly ash was also put forward at last.
