磷石膏在公路路基中的应用探讨
|
摘要
我国磷化工行业每年的磷石膏排放量超过5000万吨,这占据了工业复产石膏的七成以上,并且依然以每年15%的速度增长。传统的管理中,磷复肥企业都采取推存法的方式进行处理,不仅利用率低并且造成环境污染,然而,磷石膏可以用于路基填料,本文就简要地分析了这一应用。
The annual phosphogypsum emission of the phosphorus chemical industry in China has exceeded 50 million tons,which accounts for more than 70% of the re-produced industrial gypsum,and is still growing at an annual rate of15%.In traditional management,phosphate and compound fertilizer enterprises adopt the method of deposit,but this not only causes low utilization rate but also environmental pollution.However,phosphogypsum can be used as roadbed filler.This paper briefly analyses this application.
