摘要:

磷石膏长期堆存对生态环境及人类健康的危害日益突出,其资源化是缓解该问题的重要路径之一。概述了磷石膏的物化特性及其对环境的影响,在此基础上介绍了其在传统建材、农业、化工、环保领域,以及在纳米晶须、磷、氟类高附加值产品等资源化领域的研究现状。分析了阻碍磷石膏规模化利用的原因,主要存在其资源化水平偏低、系统性不足、经济性与环境效益不平衡等问题。此外,磷石膏中杂质影响机制尚未完全明晰,杂质分离与纯化待深化研究。指出未来技术的发展趋势,磷石膏资源化技术需要从单一或部分资源化路径向全流程资源化方向转变,实现综合效益提升,其中改进或开发高值资源化技术决定了磷石膏资源化水平。同时资源化技术规模化应用仍亟需跨学科融合,提升资源化产品性能并降低成本。此外有必要开展低碳型磷石膏资源化技术及工艺研究,契合碳中和目标。

Abstract:

The long-term storage of phosphogypsum is increasingly harmful to the ecological environment and human health.Its recycling is one of the important ways to alleviate such problem.The physical and chemical properties of phosphogypsum and its impact on environment were summarized.On this basis,the research status of phosphogypsum in the fields of traditional building materials,agriculture,chemical industry,environmental protection,and the resource utilization of high value-added products such as nano whiskers,phosphorus and fluorine chemicals were introduced.The reasons that hindered the large-scale utilization of phosphogypsum lay in its low utilization level,lack of systematicness,and imbalance between economic and environmental benefits.In addition,the influence mechanism of impurities in phosphogypsum was not completely clear,and its separation and purification needed to be further studied.Meanwhile,the large-scale application of such technology still needed to improve products performance and reduce costs.Also,it was necessary to carry out research on low-carbon phosphogypsum recycling technology and process,which was consistent with the goal of carbon neutralization.

Key words: phosphogypsum, resource utilization, whole process, high added value
