Coal based columnar activated carbon It is a cylindrical shape made of selected coal as raw material, kerosene as binder, after grinding, mixing, extrusion and carbonization Activated carbon 。

The coal based columnar activated carbon has large specific surface area, developed pores, high strength, strong adsorption capacity, and good chemical stability. It can be widely used in chemical, pharmaceutical, food and other harmful gases and microbial purification and filtration. It has good adsorption effect on benzene, alcohol and other harmful gases with low whisk point and can be recycled.

Column activated carbon adsorption:

　　 activated carbon adsorption It refers to the adsorption of one or more substances in water by the solid surface of activated carbon to achieve the purpose of purifying water quality.

Factors affecting adsorption of coal columnar activated carbon:

Adsorption capacity and adsorption speed are the main indicators to measure the adsorption process, and the adsorption capacity is measured by the adsorption capacity. The adsorption rate refers to the mass loss of adsorbents per unit weight in unit time. In water treatment, the adsorption speed determines the contact time between sewage and adsorbent.

Application of coal based columnar activated carbon in sewage treatment:

Due to the high requirements of activated carbon for water pretreatment and the high price of activated carbon, activated carbon is mainly used to remove trace pollutants in wastewater in wastewater treatment to achieve the purpose of purification.
