| 摘 要： | 粉煤灰一直被认为是固体废物,其资源属性和环境属性未能得到认可。本文从矿物资源角度,将粉煤灰"传统"的固体废物概念转变到"非传统"的矿物资源上来,提出了粉煤灰的矿物学资源属性和环境属性,探讨了它作为矿物资源在建材、化工和农业等领域的应用,阐明其环境属性。粉煤灰的环境效应体现在对陆地生态系统和水生生态系统影响与危害。然而,粉煤灰在治理环境污染和保护生态方面也有着积极的作用,如处理废水、烟气脱硫和合成环境功能材料等。

| Abstract: | Fly ash was used to be considered as just a kind of solid waste regardless of its resource attribute and environmental attribute.This paper has changed fly ash from the conventional conception of solid waste to unconventional conception of mineral resource,defined the resource attribute and environmental attribute of fly ash,discussed possible application of fly ash to the fields of construction,chemical industry,and agriculture as an unconventional mineral resource.It was indicated that fly ash has special environmental attribute,as it was badly influenced or harmful to the terrestrial ecosystem and hydrophily ecosystem,but it could play important and positive role for treating environment pollution and protecting ecosystem,such as for treating wastewater,desulfurizing smoke,and synthesizing new environmental materials,etc. |
