摘要
介绍了粘土矿物在处理含重金属废水方面的应用及吸附机理,并针对粘土矿物吸附材料遇水易分散粉化、固液分离难、吸附剂不能重复利用、易造成二次污染的缺点,阐述了加强粘土矿物吸附材料吸附性能的改性方法及改性后对废水中重金属处理的应用;可对矿井废水的达标排放及再生回用提供理论依据。
This paper introduces application and absorption mechanism of clay minerals in the treatment of wastewater with heavy metals. The clay minerals have some shortcomings： liability of dispersion and pulverization, difficult solid and liquid separation, non-recycled adsorbents, and sec- ond pollution. Therefore, the absorption ]performance of the materials could be reinforced by modification. The paper presents the modified method and its application in the treatment of heavy metals in wastewater. The study can provide theoretical evidences for discharge with standards and recycle of mine wastewater. Towel
