天然吸附材料及其改性后处理电镀废水的应用现状

Present situations of natural adsorption materials and their modifications used to treat electroplating wastewater

吸附法是目前公认的对重金属废水处理的有效和经济的方法。以我国丰富的天然材料为原料,围绕绿色环境、绿色生态等,从减少环境污染和高效利用废弃资源的角度出发,利用天然吸附材料以及经改性后得到的材料,研究了各种天然材料如硅藻土,凹凸棒,膨润土,生物秸秆等对电镀废水中重金属污染的废水中Ni^(2+),Gr^(6+),Cu^(2+),Pb^(2+)等吸附情况的研究。

Adsorption method has broadly applied prospect as it has the advantages with easy operation, high removal rate,good stability, litter or no secondary pollution, renewable absorbent and low cost. This article introduced natural adsorption material included diatomite, bentonite, attapulgite and charcoal which is used to treat electroplating wastewater.
