摘要
为了更好地探索改性硅藻土在水处理领域的应用,介绍了硅藻土的三类改性方式(无机改性、有机改性、活化处理)与基本原理,总结了国内外应用改性硅藻土处理生活污水、含重金属离子废水、造纸废水与印染废水的研究现状,讨论了改性硅藻土作为一种新型吸附材料在水处理领域的发展趋势与挑战。
To explore the application of modified diatomite in water treatment, three modification approaches of diatomite （inorganic modification, organic modification and activation treatment） and their adsorption mechanisms are introduced. The application of modified diatomite in domestic sewage, heavy metal ions-containing wastewater, papermaking wastewater and dyeing wastewater are reviewed. Besides, the development trends and challenges of modified diatomite as a promising adsorption material in water treatment field are discussed.
