摘要
从粉煤灰的理化性质出发,综述了粉煤灰在污水处理方面的应用,包括粉煤灰处理废水中的酸/碱染料,粉煤灰吸附废水中的铬离子/铅离子,粉煤灰处理含氟废水方面的研究进展,指出了粉煤灰在废水处理方面存在的问题和对策.
Based on the physical and chemical properties of coal fly ash, the application of coal fly ash in wastewater treat-ment was summarized. Specifically, the content includes the treatment of wastewater containing acid/base dyes, chromium ion/lead ions, and fluorine ions. Coal fly ash can effectively remove acidic dyes, alkaline dyes, heavy metals and fluorine ions. At last,the existing problems of research and application of coal fly ash in wastewater treatment and their countermeasures were put forward.
