Excuse me, what is the waste activated carbon mainly used for?

Activated carbon is a black porous solid carbon. In the early days, wood, hard fruit shells or animal bones were used as raw materials, which were carbonized and activated, and then pulverized with coal or carbonized and activated with uniform coal particles. The main component is carbon, and contains a small amount of oxygen, hydrogen, sulfur, nitrogen, chlorine and other elements. Activated carbon is a kind of porous carbon with low bulk density and large specific surface area, because microcrystalline carbon is irregularly arranged in structure and there are pores between cross connections, which will produce carbon tissue defects when activated. The specific surface area of ordinary activated carbon is between 500 ~1700 m2/g. Activated carbon is an industrial adsorbent with strong adsorption performance and is widely used. Activated carbon is a hydrophobic adsorbent made of carbonaceous materials through high temperature carbonization and activation. Activated carbon contains a large number of micropores and has a huge specific surface area, which can effectively remove chromaticity and odor, and can remove most organic pollutants and some inorganic substances, including some toxic heavy metals, from secondary effluent. The factors affecting the adsorption of activated carbon are: the characteristics of activated carbon; The characteristics and concentration of the adsorbate; PH value of wastewater; Suspended solid content and other characteristics; Contact system and operation mode, etc. Activated carbon adsorption is the most important and effective treatment technology in advanced treatment of municipal sewage, which has been widely used.
