摘要
粉煤灰是煤高温燃烧后的产物,在形成过程中形成了一定的多孔结构和较大的比表面积,具有一定的吸附能力,可以作为水处理材料。但由于原性粉煤灰吸附性能有限,对水中污染物的去除率较低,不能满足水处理的实际要求。因此,研究热点集中在对粉煤灰进行改性处理,增加粉煤灰中的活性组分,增大粉煤灰的比表面积,提高其性能,从而增强其对废水处理的效果。粉煤灰在废水处理领域的应用,增加了粉煤灰的综合利用途径,同时以废治废,符合节能环保政策。笔者对粉煤灰的改性方法及其在废水处理中的应用现状进行了总结,以期对粉煤灰的在废水处理中的综合利用提供参考。
Fly ash is a high temperature coal combustion products, the formation of a porous structure and large specific surface area, has certain adsorption capacity, can be used as material for water treatment.But because of raw fly ash adsorption properties limited, the water pollutant removal rate is low, can not meet the practical requirements of water treatment. Therefore, research focus on the fly ash modified fly ash, increases in the active components of fly ash, increases the specific surface area; improve its performance, thereby enhancing the effect of wastewater treatment. The fly ash modified method and its application in wastewater treatment are summarized, with a view of fly ash in waste water treatment by using reference.
