磷石膏是湿法磷酸生产的副产物，由于其杂质含量高、成分复杂，长期以来难以处理，多以堆存方式处理，对环境产生重大危害。介绍磷石膏的产生过程、主要杂质赋存形式及危害。重点阐述磷石膏无害化研究现状以及资源化利用现状，无害化研究主要包括物理法、化学法以及热分解法三大类，经无害化处理后的磷石膏主要可应用于建材、化工、农业三大领域。
Abstract：Phosphogypsum is a by-product of wet-process phosphoric acid,which is difficult to deal with for a long time due to excessive impurities and complex composition,and it is mainly stockpiled,which causes major harm to the environment. The production process,impurity types and storage status of phosphogypsum are introduced. The harmless research mainly includes three categories:physical method,chemical method and thermal decomposition method,and the phosphogypsum after harmless treatment can be mainly used in the three fields of building materials,chemical industry and agriculture.
