Special activated carbon for sewage treatment
1. Activated carbon water purification
Activated carbon has been used in the field of water treatment for about 70 years. The United States used powdered activated carbon for the first time to remove the odor generated by chlorophenol. After that, activated carbon has gradually become one of the effective measures for deodorization, color removal and odor removal in the water treatment process. one. A large number of studies have shown that activated carbon has a good adsorption effect on dichlorophenol, trichlorophenol, organic matter in pesticides and disinfection by-products such as dichloroacetic acid and trichloroacetic acid, and its purification effect has been recognized.
2. Industrial wastewater
Activated carbon used to treat wastewater can effectively ensure the stability of the effluent quality. At the same time, the combined use with other methods can effectively improve the purification effect, and the appreciation of the effluent can reach the drinking water standard. For example, when treating coking wastewater, after the activated carbon with a mass concentration of 3g/l is used for adsorption, 1.5g/l H2O2 and 0.4g/l Fe2+ are used for catalytic treatment, and the COD removal rate reaches 96.3%. In wastewater treatment, the COD removal rate can reach 98.74%.
