浅述利用磷石膏制硫酸铵生产工艺及发展前景

Ammonium sulfate production from phosphogypsum production technology and development prospect of utilization

阐述了磷石膏堆放造成的污染问题及利用的可能途径,认为仅靠生产建材难以完全消耗磷石膏,重点开发磷石膏制硫酸铵生产是解决磷石膏堆存问题的有效途径,浅述了硫酸铵生产现状及磷石膏制硫酸铵的生产工艺,随着工业化的顺利实施,为我国磷化工行业技术进步、产业结构调整和可持续发展产生积极影响。

The article discusses a phosphogypsum stack causing pollution problems and possible ways of use. Production building materials alone is difficult to completely consume phosphogypsum. Focusing on development of ammonium sulfate production from phosphogypsum are effective ways to solve storage issues of phosphogypsum, the production status of ammonium sulfate and ammonium sulfate production from phosphogypsum process discussed, with the successful implementation of industrialization. It should have a positive impact to technical progress of phosphorus chemical industry, the adjustment of industrial structure and sustainable development in China.
