摘要
硅藻土作为一种用途广泛的非金属材料,在废水处理中的应用受到重视。主要介绍了硅藻土的理化性质、吸附功能以及国内外的利用现状,阐述了硅藻土相关产品的用途和硅藻土处理草浆造纸废水的效果参数,对近年来改性硅藻土和硅藻土基复合吸附剂的制备方法及其在废水中除磷的研究现状,包括对添加某些特定金属阳离子对硅藻土进行改性的问题进行了综述,并展望了其未来的发展趋势。
Being as a kind of widely used non-metallic material, diatomite is valued for for its application in wastewater treatment. This paper mainly introduces the physical and chemical properties, adsorption function and current utilization of at home and abroad of diatomite and its related products, and the effect parameters of diatomite in treating straw pulp papermaking wastewater, and reviews the research status of the preparation methods of modified diatomite and diatomite-based composite adsorbent in recent years including the modification of diatomite by adding some certain specific metal cations, and forecasts its future development trends.
