粉煤灰在工业生产中的应用

Application of Fly Ash in Industrial Production

我国用电量连年增加,燃煤电厂排放的粉煤灰也随之增加,其造成的环境问题日益严重。由于粉煤灰的利用量比排放总量少很多,所以开发并利用粉煤灰的新领域成为研究热点。文章主要阐述了粉煤灰在水泥、建筑、废旧塑料、轨枕、矿井防灭火、废水处理和烟气处理等工业生产中的应用,最后对今后粉煤灰在工业生产中的应用进行了展望。

As electricity increases every year in our country, the emissions from coal-fired power plants fly ash also increase and the environmental problem of fly ash is increasingly serious. Due to the use of fly ash much less than the total emissions, new areas of development and utilization of fly ash become a research hotspot. The fly ash is expounded mainly in the cement, construction, waste plastics, sleeper, mine fire prevention and extinguishing, application in wastewater treatment and flue gas treatment and other industrial production the paper. At last application of fly ash in the future in the industry is prospected.
