| 摘 要： | 以一家金属材料厂生产过程中产生的废铝渣作为研究对象,通过对溶解条件和聚合工艺的优化,制备了聚合硫酸铝。将制备的聚合硫酸铝分别用于模拟浊度水及高色度高浓度有机工业废水的处理,实验结果表明,利用工业废渣所制得的聚合硫酸铝具有较好的除浊、脱色、去除COD效果。此工艺不仅可回收利用废铝渣,又可省去废渣处置费用,为废铝渣的综合利用提供了实用技术。

| Abstract: | The treatment and utilization of industrial wastes was studied centering on resource recovering. The disposal aluminum from a metal material factory was selected as an example. The polyaluminium sulfate was made through optimizing the dissolve conditions and polymerization processes. The flocculating results showed that polyaluminum sulfate (PAS) had a better performance on the removal rate of turbidity, color and COD for treating simulated sewage and high-concentration organic wastewater. Aluminum scrap can be reused and its disposal expense can be saved by this process. It is an applied technology for reuse of aluminum scrap. |
