中国磷石膏资源化利用的展望与思考

Outlook and thinking of phosphogypsum comprehensive utilization in China

介绍了目前磷石膏资源化利用在国内面临的两大难题和必须解决的两个基本问题。随着人口、环境资源的矛盾日益突出,由于种植大量使用化肥和农药,导致产量及土壤中的肥效、药效下降,并造成环境严重污染,因此中国的土壤改良问题迫在眉睫;磷石膏窑外分解制硫酸联产土壤调节剂、水泥技术提出了最为有效的途径和创新思路,引起了世界各国农业、磷化工学者的日益关注,对我国和世界磷化工、农业生产的可持续发展都是一件很有意义的创新。

Two problems to be facing and two basic issues to be solved in phosphogypsum comprehensive utilization at present are introduced. With opposition between population and environmental resources, extensive usage of fertilizer and pesticide led to reduction of output, fertilizer efficiency and pesticide effect in soil, resulting in serious environmental pollution, so soil improvement of China was extremely urgent. Co-production technology of sulphuric acid, soil conditioner and cement by phosphogypsum decomposition outside kiln provided the most effective ways and innovative thinking, causing increasing attention of scholars from global agricultural and phos- phorus chemical industries, being a significant optimization and innovation for sustainable development of phosphorus chemical industry and agriculture in China and worldwide.
