溶济萃取法处理含硫酸及硫酸盐的废水

Treatment of Wastewater Containing Sulfuric Acid and Sulfate by Solvent Extraction Process

采用溶剂萃取法处理含硫酸及硫酸盐的工业废水 ,主产优质农用硫酸钾 ,副产氯化铵和氮钾复合肥 ,整个工艺过程基本无三废排放 ,实现了对该废水的综合有效治理。

Industrial wastewater containing sulfuric acid and sulfate can be treated by solvent extraction process to produce potassium sulfate with high quality as main product, and ammonium chloride and nitrogenour phosphatic fertilizer as byproducts. The process can realize comprehensive and efficient treatment of the wastewater basically without discharging wastes.
