钢精制副产品合成聚合硫酸铁可行性研究

Cost-effective Analysis of Making PFS from Byproducts of Steel-making

利用正交实验,考察影响合成PFS反应速度的几个因素,认为温度80℃,压力(O2)为0.2MPa,催化剂加入量为3(%Fe),MFe∶MSO2-4=1∶1.35,搅拌速度为(800r/min)的条件为最佳工艺反应条件。上述条件下,利用抚顺钢厂钢精制副产品硫酸亚铁渣合成PFS絮凝剂,其各项指标完全符合GB 14591-93标准,为硫酸亚铁渣的综合利用提供了技术参考与理论依据。

Ferrous sulfate as a steel-making residue is used to prepare poly-ferric sulfate (PFS), a kind of flocculants for water treatment. This paper describes the orthogonal test to investigate the optimum condition for producing PFS, and cost-effectiveness for the recovering of waste is analyzed.
