摘要
本文介绍磷石膏资源化利用的政策趋势,对现有磷石膏资源化利用途径进行分析和评述,分析了磷石膏化学分解工艺的研究和应用进展。化学分解法磷石膏综合利用技术充分利用硫、钙两种资源,是磷石膏最好的利用途径,值得主管部门队相关技术进行评估加速化学分解法磷石膏资源化利用的工业化试验和应用推广。
This paper introduces the policy trends of phosphorus gypsum resource utilization, analyzes and reviews the existing phosphorus gypsum resource utilization methods, and analyzes the research and application progress of phosphogypsum chemical decomposition process. The chemical decomposition method comprehensive utilization technology of phosphogypsum makes full use of the two resources of sulfur and calcium, which is the best utilization way of phosphogypsum. It is worthy of evaluation by the relevant department team to accelerate the industrialization test and application promotion of the chemical decomposition of phosphate gypsum.
