粉煤灰在煤化工行业的应用及资源化发展策略研究

Application of Fly Ash in Coal Chemical Industry and Resource Development Strategy Study

作为燃煤电厂在生产过程中排出的主要固体废物,粉煤灰曾对我国环境造成了明显污染。近年来,随着粉煤灰综合利用技术的进步和产业引导,这种固废已成为重要的煤化工与建筑原料。文章首先分析了电厂中粉煤灰的形成与危害,综述了其应用原则,从3个方面探讨了粉煤灰在煤化工行业及建筑行业的应用情况,然后提出了资源化发展策略。

As a major solid waste discharged by coal-：Fired power plants in the production process, fly ash had caused significant pollution to our environment. In recent years, with the advances in technology and industry guidance on utilizatien of fly ash, solid waste has become an important coal chemical industry and construction materials. This article first analyzes the coalification trades fly ash formation and harm, and it~,~ application principle, discusses the application of fly ash in the coal chemical industry fror^a three aspects, and put forward the resource development stratezv.
