摘要
概述了磷石膏的来源、成分、杂质的危害以及目前国内外的排放量,简单介绍了国内外磷石膏综合利用的现状以及磷石膏综合利用的相关技术。将原位生物修复技术引入对磷石膏堆场的处理,重点介绍了磷石膏堆场的植物稳定修复技术,通过改良磷石膏堆场的成分和植物物种的选择达到综合从源头控制磷石膏堆场的污染,为磷石膏的生态修复提出今后的研究方向。
The sources,the ingredients,the harm of impurity and the current domestic and international emissions of phosphorus gypsum were introduced. The domestic and international status quo of phosphorus gypsum comprehensive utilization as well as the related technologies was introduced. In situ bioremediation technology was introduced to the handling of phosphogypsum stacks. Highlight was the phosphogypsum stacks plant stable repair techniques. By modified phosphogypsum stacks composition and selection of plant species,comprehensive from phosphogypsum stacks of pollution source control was achieved. Future research directions for the ecological restoration of the phosphogypsum were proposed.
