摘　　要：随着我国磷复肥的发展,湿法磷酸生产副产固体废渣磷石膏量逐年增多,因其杂质种类复杂,综合利用面临严重挑战。阐述目前我国磷石膏综合利用技术的现状。分析云天化集团利用磷石膏与高硫煤制硫酸联产水泥的优势,采用此方法每年将减少300万t的固渣转运量,建议尽快开展此方面的研究工作。With the development of phosphate and compound fertilizer in China, the output of by-product phosphorusgypsum of wet-process phosphoric acid production is increased year by year, because of its impurity species complex, the comprehensive utilization faces a serious challenge. The present situation of phosphogypsum comprehensive utilization technology in China are discussed.The advantage of using phosphogypsum and high sulfur coal to produce sulfuric acid and cements in Yuntianhua Group is analyzed, using this method the solid residue transport capacity of 3 million ton pre year is reduced, it is suggested that the research work should be undertaken as soon as possible.
