摘要
概述了近几年国内外粉煤灰吸附剂研究情况,讨论了粉煤灰吸附剂在去除水体中氮、磷、重金属离子,净化烟气中SO2、NOx、Hg等有毒有害污染物的应用,此外,还阐述了粉煤灰负载壳聚糖和制备沸石分子筛的应用研究,分析总结了粉煤灰吸附剂目前存在的问题,为粉煤灰吸附剂未来的发展方向和资源化利用奠定了理论基础。
Fly ash, the solid waste of coal fired power plants generated during the coal energy combustion which is recognized as an environmental pollutant. Its physical and chemical properties and various utilizations have been widely investigated since last three decades. In this paper, the development of coal fly ash as a low-cost adsorbent for the removal of nitrogen and phosphorus salts, flue gas and heavy metal was reviewed, the synthesis of zeolite and fly-ash coated with chitosan have been briefly introduced. The existing problems and future research in this area were also discussed.
