Products more bleaching, purification, purify, deodorant, to smell, the carrier, purification, recycling, and other functions. Packaging and storage: 50kg bags, plastic bags, the product should be stored in indoor dry place. Nutshell activated carbon analysis of the major technical indicators project test data analysis project test data iodine value> 900mg / g bulk density 0.45-0.55g/cm3 large surface area ≥ 1000m2 / g dry alkali ≤ 10% of the total volume ≥ 0.9cm3 / g strength> 88 % stupid adsorption rate ≥ 450mg / g PH value ≈ 7 Moisture <5% activated carbon Nutshell Notes 1 nut shell activated carbon during transport to prevent the hard substance mixed-like, not to step on, tread, to prevent carbon particles crushing impact quality. 2, the storage should be stored in the porous adsorbent, shipment, storage, and use of the process, must absolutely prevent flooding, due to flooding, a large number of water filled with activity gap, and make it useless. 3, to prevent the tar-like substance in the process, should be prohibited from the tar-like substance into the activated carbon bed to prevent blockage of the activated carbon gap, it lost the adsorption. Best decoking equipment purge gas. 4, fire activated carbon storage or transport, to prevent the fire source in direct contact, in case of fire, the activated carbon regeneration avoid the intake of oxygen and renewable thorough regeneration must be reduced to below 80 ℃ steam cooling, otherwise the temperature is high, the case of oxygen, activated carbon spontaneous combustion. Nutshell activated carbon in wastewater treatment due to the high carbon water pretreatment requirements, and the expensive price of activated carbon in wastewater treatment, activated carbon is mainly used to remove trace contaminants in the wastewater to reach the depth of purification purposes . 1. Activated carbon treatment of wastewater containing chromium. Chromium plating a larger amount of a metal raw material, and the hexavalent chromium with the different pH values, respectively, to exist in different forms in the wastewater. Activated carbon developed porous structure and high specific surface area, has a strong physical adsorption capacity of Cr (VI) in the wastewater can be effectively adsorbed activated carbon surface of a large number of oxygen-containing groups such as hydroxyl (-OH ), carboxyl (-COOH), they all have electrostatic adsorption function, chemical adsorption of Cr (Ⅵ). Completely can be used for treatment of Cr (VI) in electroplating wastewater after adsorption of waste water can meet the national emission standards. The tests showed that: mass concentration of Cr (Ⅵ) solution to 50mg / L, pH = 3, and adsorption properties of activated carbon adsorption time 1.5h and the removal rate of Cr (Ⅵ) achieve the best results. Therefore, the use of activated carbon treatment process of wastewater containing chromium activated charcoal solution of Cr (VI) of the combined effects of physical adsorption, chemical adsorption, chemical reduction results. Chromium waste water treated with activated carbon adsorption and stable performance, high processing efficiency, low operating costs, there is a certain degree of social and economic benefits. Charcoal cyanide wastewater treatment. Industrial production of gold and silver wet extraction, chemical fiber production, coking, ammonia, electroplating, gas production, and other industries use cyanide or byproduct of cyanide, and thus in the production process is bound to a certain amount of cyanide-containing emissions wastewater. Activated carbon for purifying waste water has a fairly long history, applied to the treatment of wastewater containing cyanide reported in the literature is also increasing, but due to the small CN_, HCN on activated carbon adsorption capacity, generally 3mgCN/gAC ~ 8mgCN/gAC the different varieties uneconomical in processing costs. Activated carbon treatment of mercury-containing waste water. Performance of the adsorption of mercury and mercury compounds, but the activated carbon adsorption capacity is limited only suitable for the treatment of wastewater with low mercury content. If the higher concentration of mercury can be treated with chemical precipitation treatment mercury 1mg / L, high up to 2-3mg / L, and then use activated carbon for further processing. Carbon treatment of phenol wastewater. Phenolic wastewater widely from petrochemical plants, resin plant, coking plant and refinery chemical plant. The experiment proved: activated carbon adsorption properties of phenol, the temperature is not conducive adsorption, the adsorption capacity decrease; elevated temperature reaches adsorption equilibrium time. There exists an optimum value, the amount of activated carbon and adsorption time in acidic and neutral conditions, the removal of little change; strong alkaline conditions, the phenol removal sharp decline, the alkali is, the stronger the adsorption effect is worse. 5. Activated carbon treatment of wastewater containing methanol. Activated carbon can adsorb methanol, but not strong adsorption capacity, only suitable for processing with low methanol wastewater. The project run results show that the mixture COD reduced from 40mg / L to 12mg / L, the removal rate of 93.16% to 100% of methanol, water quality to meet back the water used in the boiler desalination water system water quality requirements.
