摘要
在环境污染中,铅、镉、汞、铬、砷这五种重元素属于一类污染物,被称为"五毒",是最常见、危害最严重的一类物质,其引发的水污染问题更是严重威胁着人类的健康,吸附法作为一种操作简单、净化作用明显、处理量大、成本低的水处理技术,近年来在处理重金属污染方面取得了很多显著的新成果。文中总结了近年来国内科研工作者们在采用吸附法处理重金属废水污染方面的研究进展,并对其吸附原理和工艺特点进行了评述,对处理重金属废水污染的前景进行了展望。
Among the environmental pollution,the five heavy elements of lead,cadmium,mercury,chromium and arsenic belong to the first class of pollutants,which are called“five poisons”.They are the most common/most harmful type of substances.And the water pollution caused by them become a serious threat to human health.As a simple operation,the purification method has achieved many remarkable new achievements in dealing with heavy metal pollution in recent years because of its large treatment volume and the low cost.In this paper,the research progress of domestic researchers in the treatment of heavy metal wastewater by adsorption was summarized,while the adsorption principle and process characteristics are reviewed.And the prospect of heavy metal wastewater pollution was prospected.
