摘要
本文综述了国内外粉煤灰环境效应研究的进展,包括处理过程中对陆地和水生态系统的效应以及利用过程中对农业生态、矿山生态的影响。粉煤灰安全贮存具有重要环境学意义;在改良土壤和矿山生态综合整治方面粉煤灰具有广阔利用前景。加强粉煤灰环境效应研究,有利于贯彻"贮用并重,积极利用"的方针,趋利避害,实现粉煤灰综合治理。
This paper reviews progress on study of environmental effects of powerplant coal ash in China and foreign countries.The effects include that on terrestrial ecosystems and on aquatic ecosystems of ash disposal and on agriculture ecosystem and mine ecosystem of ash utiliza- tion.Safe disposal of ash has important significance for environmental. Powerplant coal ash can be utilized,being ash amendment of agricultural soils and ash a- mendment of mine spoils and wastes studying environmental effects of ash in a thorough-go- ing way is favourable for prevent and cure ash pollutation synthetically.
