摘要

通过使用表面改性、金属氧化物、有机物、不同碳源等多种方法对膨胀石墨进行改性，使其吸附性能得到明显提高，同时，增强了对污水中的油类、重金属、色素和酚类等难降解物质的处理能力，对多种典型废水处理具有良好的处理效果。

Abstract

Expanded graphite is modified by surface modification,metal oxide,organic matters and different carbon sources to improve its adsorption performance while to enhance its ability to treat with refractory substances in sewage such as oil,heavy metals,pigments and phenols,which has a good treatment effect on various typical wastewater.
