Purification effect of shell activated carbon

Nutshell activated carbon is generally used for water purification and sewage treatment. Because in wastewater treatment, nut shell activated carbon is mainly used to treat fine pollutants in water to achieve the deepest purification.

Nutshell activated carbon treatment of mercury-containing wastewater. Activated carbon has the function of adsorbing mercury and mercury-containing compounds, but its adsorption capacity is limited, and it is only suitable for treating wastewater with low mercury content. If the concentration of mercury is high, it can be treated by chemical precipitation first. After treatment, the mercury content is about 1mg/L, and when it is high, it can reach 2-3mg/L, and then activated carbon is used for further treatment.

Activated carbon treatment of methanol-containing wastewater. Activated carbon can adsorb methanol, but the adsorption effect is not strong, and it is only suitable for treating wastewater with low methanol content. The operation results of the project show that the COD of the mixed liquid can be reduced from 40mg/L to below 12mg/L, the removal rate of methanol can reach 93.16%~100%, and the quality of the effluent can meet the water quality of the boiler desalination system. standard.

Longxin fruit shell activated carbon uses high-quality coconut shell, peach shell, walnut shell, jujube shell and other fruit shells as raw materials, and the activated carbon is refined by carbonization, activation, superheated steam catalysis and other processes. Processed activated carbon. It has the advantages of good wear resistance, developed voids, high adsorption performance, high strength, easy regeneration, economical and durable, and is widely used in life, industry, liquid phase adsorption, water purification, gas phase adsorption. Especially suitable for power plants, petrochemicals, oil refineries, printing and dyeing textile industry, food and beverage, electronic high-purity water, drinking water, industrial water reuse and other industries. It can more effectively adsorb free chlorine, phenol, sulfur, oil, colloid, pesticide residues and other organic pollutants in water, residual chlorine, semi-dechlorination value, and recovery of organic solvents, etc.
