Tangshan coconut shell activated carbon manufacturers 13436502885

 Beijing Water Biqing high quality coconut shell activated carbon apricot shell, peach shell, walnut shells, shells and other dates coconut shell as raw materials, carbonization, activation, superheated steam Cui refining process, the appearance of black amorphous particles, the An activated carbon production and processing of the series. Has good abrasion resistance, gap developed, high adsorption performance, high strength, easy regeneration, economic and durable and so on. Beijing Biqing water coconut shell activated carbon is widely used in domestic, industrial, liquid adsorption, water purification, gas adsorption. Especially suitable for power plants, petrochemical, refinery, textile printing and dyeing, water and beverage, pharmaceutical water, electronic high water, drinking water, industrial water reuse and other industries. More effective adsorption of free chlorine, phenol, sulfur, oil, resin, pesticide residues and other organic contaminants, chlorine, dechlorination half the value, as well as recycling of organic solvents. 1. Beijing Biqing coconut shell activated carbon water treatment wastewater containing chromium. Chrome plating in a larger amount of a metal material, hexavalent chromium in the waste water with pH values ??were different in different forms. Activated carbon has a very well-developed porous structure and high specific surface area, with a strong physical adsorption capacity. Tests showed that: the solution Cr (Ⅵ) concentration of 50mg / L, pH = 3, when the adsorption time 1.5h, adsorption properties of activated carbon and Cr (Ⅵ) removal are the best results. Therefore, the use of chromium-containing wastewater treatment process of activated carbon is the result of the combined effect of activated carbon in solution Cr (Ⅵ) physical adsorption, chemisorption, chemical reduction, etc.. Activated carbon treatment of wastewater containing chromium, adsorption stable performance, high efficiency, low operating costs, there is a certain social and economic benefits. 2. Beijing Biqing coconut shell activated carbon water treatment wastewater containing cyanide. In industrial production, gold and silver wet extraction, chemical fiber production, coke, ammonia, electroplating, gas production and other industries are using water or water byproduct material, and thus in the production process is bound to emit a certain amount of Wastewater. Activated carbon is used to purify water has a long history, used in treatment of wastewater containing cyanide reported more and more. But because CN_, small HCN on activated carbon adsorption capacity, usually 3mgCN / gAC ~ 8mgCN / gAC due different varieties, the processing costs uneconomical. 3. Beijing Biqing coconut shell activated carbon water treatment of wastewater containing water. Activated carbon adsorption of water and have a performance water-containing compounds, but the limited absorption capacity, only suitable for the treatment of waste water containing low net amount of water. If water containing high concentrations, can be treated by chemical precipitation, including water after handling about 1mg / L, high up 2-3mg / L, then use charcoal for further processing. 4. Beijing Biqing coconut shell activated carbon water treatment of phenol wastewater. Phenolic wastewater from a wide range of petrochemical plants, resin plant, coking plant and oil refinery plants. The experiment proved that: good Adsorption on activated carbon, the temperature is not conducive to absorption, adsorption capacity is reduced; but elevated temperatures shorten the time to reach adsorption equilibrium. Under the amount of activated carbon adsorption time and there is an optimal value, and neutral conditions, the removal rate changed little; strong alkaline conditions, the removal rate of a sharp decline, the more strongly alkaline, adsorption effects worse.
