黏土矿物材料在重金属废水处理中的应用

Application of clay mineral materials to the treatment of heavy metals wastewater

简要介绍了黏土矿物材料的结构特征及基本特性,重点分析了黏土矿物材料处理重金属废水的机理,列举了部分研究成果,指出了黏土矿物材料处理重金属废水存在固液分离难、吸附剂不能重复利用、易造成二次污染等问题,提出了加强黏土矿物吸附材料的造型、重复利用等方面研究的具体措施。

The structural characteristics and basic properties of clay mineral materials are introduced simply, and the mechanism of the treatment of heavy metals wastewater with clay mineral materials is analysed emphatically. Some of the research achievements are enumerated. The problems ,for example, the solid clay mineral materials are hard to be separated from the liquid, the adsorbents can not be reused, and the surroundings are etc. are pointed out. It is put forward that the research of clay mineral materials mold-making strengthened.
