絮凝-吸附法高效处理重金属元素模拟废水

Flocculation-Absorption Technique:Efficient Way to Remove Heavy Metal Elements from Simulated Wastewater

选用四种絮凝剂对实验室模拟废水的絮凝效果进行比较,选取效果最佳的絮凝剂,并分析实验条件对处理效果的影响。结果表明,即使在不同模拟废水的pH值及干扰离子共存条件下,采用化学絮凝-吸附处理法对Fe、Co、Mn、Ag四种重金属元素都可以实现高效去除。

A best flocculant has been selected from four kinds of flocculants on the basis of their flocculation effect on simulated waste water in the laboratory.The influence of the experimental condition on the treatment effect was studied.The result shows that the chemical flocculation-absorption technique can remove Fe,Co,Mn and Ag effectively from simulated wastewater even with different pH values and when interfering irons exist at same time.
