摘要:

为解决湿法磷酸生产中副产磷石膏堆存量不断增加的问题,将磷石膏净化处理后作为原料生产中量元素型土壤调理剂,介绍了生产中量元素型土壤调理剂的工艺流程及产品质量指标。以马铃薯为研究对象,以单施化肥为对照(CK)处理,开展了化肥与中量元素型土壤调理剂配施(T处理)的田间小区试验。结果表明:与CK处理相比,T处理马铃薯增产11.51%,经济效益提高28.65%。用净化处理后的磷石膏生产中量元素型土壤调理剂,不仅有助于缓解磷石膏堆存量增加的问题,还可以变废为宝,拓宽磷石膏的利用途径。

Abstract:

To solve the problem of the continuous increase in the stockpile of phosphogypsum produced as a byproduct in wet process phosphoric acid production, phosphogypsum is purified and used as a raw material to produce secondary-element soil conditioner. The process flow of producing secondary-element soil conditioner and product quality indicators are introduced. A field plot experiment is conducted using potatoes as the research object, with single application of chemical fertilizer as the control (CK) treatment, and the combination of chemical fertilizer and secondary-element soil conditioner (T treatment). The results show that compared with CK treatment, T treatment increases potato yield by 11.51% and economic benefits by 28.65%. The use of purified phosphogypsum as a source for the production of secondary-element soil conditioner not only helps alleviate the problem of increasing phosphogypsum storage, but also turns waste into treasure and broadens the utilization of phosphogypsum.
