水淬渣处理废水的研究进展

Study Progress on the Application of Granulated-Slag in Wastewater Treatment

水淬渣的微观结构特殊,比表面积大,表面能高。国内外研究表明,水淬渣吸附去除废水中的Cu2+、Zn2+、Ni2+、Pb2+、Cr6+、As3+及磷等效果良好,而且对废水中的COD、大分子有机物、油类、苯酚等也有比较好的去除率;并研究了吸附去除的机理,对水淬渣在水处理领域的应用起到了推动作用。

Granulated-slag has special microstrueture, large surface area and high surface energy. Domestic and international research indicate： The adsorption removal effect of granulated-slag is good in Cu^2＋, Zn^2＋, Ni^2＋, Pb^2＋, Cr^6＋, As^3＋ and phosphorus from wastewater, but also good for COD, macromolecular organic matter, oil, phenol in the wastewater. The adsorption mechanism of granulated-slag is researched, which plays a great role in granulated-slag application in the field of wastewater treatment.
