Abstract
The composition structure of attapulgite clay, the application in production and life at present and process of modification experiment are described in this paper, and the different effects of sewage treatment by 200 mesh and 400 mesh physical and chemical modified attapulgite clay are discussed respectively. The results showed that in domestic sewage COD removal efficiency and decolorization rate increased after a high temperature roasting or acid-modified of natural attapulgite clay. Overall, the treatment effect of 400 mesh attapulgite clay is better than 200 mesh, among which the best is 400 mesh natural attapulgite clay after 200 ¿ calcination, COD removal efficiency reached 84.54%.
