Application of activated carbon

[Application] Activated carbon is used in various fields such as chemical industry, environmental protection, food processing, metallurgy, military chemical protection, etc.

① Activated carbon for purification of sewage sources absorbs organic matter, color, odor, oil, phenol, etc.

②Organic industrial wastewater treatment.

③Inorganic industrial wastewater treatment Some activated carbons have a certain selective adsorption capacity for inorganic heavy metal ions in wastewater

④ The ozone-biological activated carbon process in the field of drinking water and micro-polluted water purification is highly valued for its high efficiency in removing dissolved organic matter and carcinogenic mutagen in water, safety and high quality of effluent water

Zhao Zhiqing and others used sludge as raw material to prepare activated carbon for the adsorption of Cr ⁶⁺ , and prepared activated carbon from the sludge of the dewatering room of the domestic sewage plant and the sludge of the dewatering room of the Juhua sewage plant.

Jiang Xinyuan and others prepared bamboo charcoal from bamboo processing residues, bamboo knots, and bamboo branches, and then used H ₃ PO ₄ as the activator to activate bamboo activated carbon at an activation temperature of 700 ℃ and different H ₃ PO ₄ concentrations.
