摘　　要：天然硅藻土的选择吸附分离能力低,且表面附着大量带负电的硅羟基,极大地降低了其吸附除磷能力,但通过改性可以有效提高其对废水中磷的吸附效果。文章归纳并总结了近年来有关改性硅藻土吸附含磷废水的研究,阐述了硅藻土的常规改性方法及其优缺点,分析了改性硅藻土处理含磷废水的应用现状,展望了改性硅藻土的研究方向,旨在为改性硅藻土的进一步研究和应用提供参考。With very low selective adsorption and separation ability,the natural diatomite bears a large number of negatively charged silanols attached to its surface,which greatly reduces its adsorption and phosphorus removal ability.The phosphate adsorption capacity of diatomite can be improved after modification.This paper systematically summarizes the researches on the adsorption of phosphorus-containing wastewater by modified diatomite in recent years,expounds diatomite modification methods and its advantages and disadvantages,and analyzes its application status in the treatment of phosphorus-containing wastewater and its future research direction,which aims to provide reference for further research and application of modified diatomite.
