磷石膏的综合利用现状及建议

Status and Prospect of Comprehensive Utilization of Phosphogypsum

总结并简述了我国磷石膏综合利用现状及最新趋势。磷化工产业的发展导致磷石膏的大量堆积,现已造成了严重的环境污染,也给磷化工产业的发展造成了巨大障碍,目前我国对环境的保护力度越来越大,所以对磷石膏的综合利用也迫在眉睫。磷石膏在制硫酸联产水泥、水泥缓凝剂、建材领域及土壤调理剂等领域有广泛的利用潜力,其中制硫酸联产水泥是最具价值的方向。

The work and new trend of comprehensive utilization of phosphogypsum in China are summarized.The development of phosphorus chemical industry leads to a large accumulation of phosphogypsum,which has caused serious environmental pollution and caused great obstacles to the development of phosphorus chemical industry.At present,the protection of the environment is becoming more and more strong in our country.Therefore,the comprehensive utilization of phosphogypsum is also imminent.Now,it has wide potential in the fields of sulfuric acid co-production cement,cement retarder,building materials and soil conditioner,and the first one is the most valuable direction.
