摘要
粉煤灰具有比表面积大、多孔性蜂窝状组织形貌、活性氧化物成分等独特的理化性能,通过简单改性即可大幅提升其吸附性能,因此在废水处理方面具有很大的应用价值。文章概述了粉煤灰的理化性能,酸改性粉煤灰吸附机理,以及酸改性粉煤灰在废水处理中的应用,并提出了需进一步研究的课题。
The fly ash has unique physical and chemical properties,such as high specific surface area,active oxide,porous and honeycomb morphology,and so on.The adsorption capacity of fly ash after modified can be improved obviously,which prove immense applied value in wastewater treatment.In the article,the physical and chemical properties of fly ash,the adsorption mechanism of acid modified fly ash,and the application of acid modified fly ash in wastewater treatment are described.Meanwhile,the subject of follow-up studies are presented.
