The composition of Waste water is complex and difficult to treat. The treatment methods mainly include oxidation, adsorption, membrane separation, flocculation, biodegradation, etc.
These methods have advantages and disadvantages, where activated carbon can effectively remove the chroosity and COD of wastewater Active carbon adsorption is mostly used for deep treatment or using activated carbon as the carrier and catalyst, and few studies use activated carbon to treat high concentration wastewater alone.
Activated carbon has a good discoloration effect on the wastewater. The discoloration rate of dye wastewater increases with increasing temperature and pH does not affect the effect of dye wastewater.
