Activated carbon is a hydrophobic adsorbent made from carbon-based materials through high temperature carbonization 

and activation. Activated carbon contains a large number of micropores, with a huge specific surface area, can effec

-tively remove chroma, odor, can remove most of the secondary water organic pollutants and some inorganic substances, 

including some toxic heavy metals. The factors affecting activated carbon adsorption are: the characteristics of acti

-vated carbon; Characteristics and concentration of adsorbed substance; The PH value of wastewater; Suspended solid 

content and other characteristics; Contact system and operation mode, etc.
