摘要
在尾矿浓缩池中添加不同种类的高分子絮凝剂、无机絮凝剂及有机絮凝剂,用实验室模拟的方法,通过几种絮凝剂的沉降试验,选择合适的絮凝剂及用量,并研究pH值及温度的影响,旨在提高尾矿的回水利用率。试验结果表明,在pH7和15℃条件下添加聚丙烯酰胺(PAM)24g/t时,絮凝效果最佳,回水利用率提高14.66%。
Putting several polymolecule flocculants, inorganic flocculants and organic flocculants in of the Oredressing Plant's Tailing. Comparing several experimental data of the flocculants by laboratory simulation, the optimum flocculent and its optimum dosage are determined. Then the pH and tempereture has been made, in order to increase the utilization of the reclaimed wastewater. Experimental data demonstrated: while Putting PAM, Sedimentation is the best in the condition of pH7.15℃ and 24g/t. And the rate of reclaimed wastewater increases 14.66%.
