摘　　要：随着城市污水水量增加,水质成分日益复杂,硅藻土作为一种新型的污水处理材料,具有较好的吸附效果。本文描述了硅藻土和改性硅藻土在污水处理中的研究进展,及其改性前后对污染物的去除效果比较,并通过此对比总结了硅藻土及改性硅藻土在水处理中的优缺点,以及其作为一种新型吸附材料为污水处理的研究提供了理论基础。With the increase of the amount of municipal wastewater, the composition of water quality becomes more and more complex.As a new type of sewage treatment material, diatomaceous earth has better adsorption effect. This paper describes the research progress of diatomaceous earth and modified diatomaceous earth in wastewater treatment, and the comparison of the removal efficiency of pollutant sbefore and after modification. Through the comparison, the advantages and disadvantages of diatomaceous earth and modified diatomaceous earth in water treatment are summarized. As a new kind of adsorption material, it provides theoretical basis of the research on wastewater treatment.
