中国磷石膏资源化综合利用研究进展

湿法磷酸工业副产物磷石膏含有可溶磷、氟，各种盐类，重金属及有机物等杂质，难于利用。巨量磷石膏的堆存，既侵占大量土地，又污染周边水、土和大气，破坏生态环境，同时严重阻碍磷化工的可持续发展，亟待开展好并大力推进磷石膏的减量化、资源化利用。介绍了我国磷石膏的产排量及分布，分析了近几年磷石膏的利用途径、利用量以及利用率，讨论了磷石膏在水泥、建材、农业及化肥行业等领域的应用研究及产业开发等，最后展望了磷石膏的资源化综合利用发展方向。 

Research Progress on Resource Utilization of Phosphogypsum in China

Phosphogypsum is a by-product originated from wet-process phosphoric acid, which contains some impurities such as soluble phosphorus, soluble fluorine, some salts, heavy metals and organic compounds, which lead to difficulty to be used. Jillion phosphogypsum accumulated not only occupies land, pollutes the circ。umjacent atmosphere and water and soil, destroys ecological environment, but also seriously hinders the sustainable development of phosphorus chemical industry. Therefore it is urgently needed to develop and vigorously promote minimization and resource utilization of phosphogypsum. The production, discharge and distribution of phosphogypsum in China were introduced. The utilization ways, utilization quantity and utilization ratio of phosphogypsum in recent years were analyzed. The applied research, resource utilization and industrial development of phosphogypsum in the fields of cement, building materials, agriculture and chemical industry were discussed. The future development direction of resource comprehensive utilization of phosphogypsum were proapected.
