摘要:
随着磷石膏堆存数量增加，磷石膏所带来的环境安全问题日益突出。由于磷石膏杂质种类多且对磷石膏产品性能影响较大，世界范围内磷石膏的综合利用率低，使其处理处置成为磷石膏产业和环保领域的研究热点和难点。本文概述了国内外磷石膏处理现状，总结了磷石膏中杂质的种类及对相关磷石膏产品性能的影响，并分析了各种磷石膏预处理方法的优缺点，综述了磷石膏在建材、工业、农业方面的应用现状，展望了磷石膏资源化利用的研究思路与方向。
With the increase of phosphogypsum storage quantity, environmental security problems are in-creasingly prominent by phosphogypsum. Because phosphogypsum contains different kinds of impurities which affect the phosphogypsum product performance, and its’ comprehensive utilization is low in the world, that makes the disposal of phosphogypsum become the research hotpots and difficulties in the field of the phosphorus gypsum industryand environmental protection. Processing status of phosphogypsum at home and abroad is introduced. Different kinds of impurities in phosphogypsum and effects of phosphogypsum product performance are summarized. The disadvantage and advantage of the pretreatment technology of phosphogypsum are discussed. Application status of phosphogypsum in building materials, industrial, agricultural is introduced and summarized. Finally, research ideas and direction of the resource technology of utilizing phosphogypsum are put forward.
