摘要
分析了磷石膏产生的主要环境问题,比对了陆良磷石膏与天然石膏的化学组分,介绍了去除磷石膏中结晶水的方法,通过试验验证了经处理后的磷石膏对硅酸盐水泥性能的影响,认为将磷石膏经中和、煅烧后制成各种石膏产品将是很有前景的产业。
The main environmental problems resulted from phosphogypsum are analyzed. The components of phosphogypsum and natural gypsum in Luliang are compared. The method of removing the crystal water from phosphogypsum is introduced. The impacts on portland cement by phosphogypsum without crystal water is tested. The resuits show that the phosphogypsum after neutralization and calcination can be made of all kinds of gypsum products which will be a potential industry later.
