Activated carbon is an adsorbent widely used in sewage treatment, which has porous, high specific surface area and good adsorption properties. This article will introduce the application effect of activated carbon in sewage treatment, including its removal effect on various pollutants and the improvement of sewage treatment efficiency.
1. The effect of activated carbon on the removal of pollutants.
1.Suspended solids removal.
Activated carbon has a strong adsorption capacity and can effectively remove suspended solids from water. Suspended solids are removed by adsorbing suspended solids on the surface of the activated carbon as the wastewater flows through the activated carbon bed.
2.Removal of organic matter.
The removal of organic matter by activated carbon mainly depends on its adsorption performance. Organic matter is adsorbed on the surface of activated carbon and then broken down by microorganisms into harmless substances such as water and carbon dioxide.
3.Heavy metal ion removal.
Activated carbon can remove heavy metal ions from water through ion exchange. When the surface of the activated carbon comes into contact with heavy metal ions, the heavy metal ions will be adsorbed on the surface of the activated carbon, so as to achieve the removal of heavy metal ions.
4.Decolorization and deodorization.
Activated carbon has a very good decolorization and deodorizing effect. By adsorbing colored substances and odorous substances in water, activated carbon can effectively improve water quality and improve sewage treatment efficiency.
Second, the improvement of the efficiency of activated carbon on sewage treatment.
1.Improve water quality.
By removing pollutants such as suspended solids, organic matter, heavy metal ions and colored substances in the water, activated carbon can effectively improve the water quality and make the treated water meet the discharge standard or reuse standard.
2.Reduce energy consumption.
Activated carbon adsorption is a physical process that consumes less energy than chemical treatment methods. Therefore, the use of activated carbon for wastewater treatment can reduce energy consumption and save energy.
3.Reduced sludge production.
Due to the adsorption of activated carbon, the contaminants in the sewage are adsorbed on the surface of the activated carbon, thus reducing the sludge production. This helps to reduce sludge disposal costs and reduces environmental impact.
4.Improve the efficiency of biological treatment.
Activated carbon can be used as a carrier for biological treatment, providing a surface for microorganisms to attach and grow. This helps to improve the efficiency of biological treatment and allows for a more thorough removal of organic matter from the wastewater.
III. Conclusion. Activated carbon has a good application effect in sewage treatment, which can effectively remove various pollutants in water and improve water quality and treatment efficiency. At the same time, the use of activated carbon can also reduce energy consumption and sludge production, reducing the impact on the environment. Therefore, activated carbon has a wide range of application prospects in sewage treatment.
