矿物材料处理废水的研究进展

矿物材料对重金属离子具有吸附、离子交换和化学活性作用，可用于废水中重金属离子的处理。目前，矿物材料和以矿物为基体的高吸附性能材料在废水处理方面的研究逐渐成为热点。本文简要介绍了矿物材料的种类、组成、特点；并详细介绍了硅藻土、膨润土、伊利石、凹凸棒石、沸石等非金属矿物材料和锰矿、铁矿等金属矿物材料在处理废水方面的应用。最后对矿物改性材料在废水应用方面存在的技术问题进行了讨论，并对其应用前景进行了展望。 

Research Progress of Minerals in Waste Water Treatment

Mineral materials have adsorption, ion exchange and chemical activity for heavy metal ions, and it can be used for the treatment of heavy metal ions in wastewater. At present, the research of mineral materials and mineral based materials with high adsorption performance in wastewater treatment has gradually become a hot spot. This paper briefly introduces the types, compositions and characteristics of mineral materials, and introduces in detail the application of mineral materials and modified mineral materials in wastewater treatment. At last, the technical problems of the application of mineral modified materials in wastewater are discussed, and the prospect of its application is prospected.
