Phosphogypsum is one of the hottest issues in the field of environmental solid waste treatment, with complex and changeable composition. Meanwhile, phosphogypsum contains a large number of impurities, thus leading to the low resource utilization rate, and it can only be stockpiled in large quantities. Phosphogypsum occupies a lot of land and poses a serious pollution threat to the ecological environment. This paper mainly summarizes the existing pretreatment and resource utilization technology of phosphogypsum. The pretreatment mainly includes dry method and wet method. The resource utilization technology mainly includes building materials, chemical raw materials, agriculture, environmental functional materials, filling materials, carbon sequestration and rare and precious extraction. Although there are many aspects of resource utilization of phosphogypsum, the existing technology is far from being able to consume a large amount of accumulated and generated phosphogypsum. Through the analysis, the comparison and mechanism analysis of the existing multifaceted and multi-level resource treatment technologies of phosphogypsum, the four promising resource utilization directions of phosphogypsum are put forward, mainly including prefabricated building materials, eco-friendly materials and soil materials, and new green functional materials and chemical fillers. Moreover, this paper summarizes the research basis of multi field and all-round treatment and disposal of phosphogypsum, which reduces repeated researches and development, as well as the treatment cost of phosphogypsum. This paper could provide a feasible research direction for the resource treatment technology of phosphogypsum in the future, so as to improve the consumption of phosphogypsum and reduce environmental risks.

磷石膏是环境固废处理领域最热门的问题之一，其成分复杂多变。同时，磷石膏含有大量杂质，导致资源利用率低，只能大量储存。磷石膏占用大量土地，对生态环境构成严重污染威胁。本文主要总结了现有的磷石膏预处理及资源化利用技术。预处理主要有干法和湿法。资源利用技术主要包括建筑材料、化工原料、农业、环境功能材料、填充材料、固碳和稀有珍贵提取。磷石膏的资源化利用虽然有很多方面，但现有技术还远远不能消耗大量积累和生成的磷石膏。通过对现有磷石膏多方位、多层次资源处理技术的分析、对比和机理分析，提出了磷石膏资源利用的四大方向，主要包括装配式建筑材料、环保材料和土壤材料，以及新型绿色功能材料和化学填料。此外，总结了磷石膏多领域全方位处理处置的研究基础，减少了重复研发，降低了磷石膏的处理成本。
