More effective adsorption of free chlorine, phenol, sulfur, oil, gum, pesticide residues and other organic pollutants, residual chlorine, semi dechlorination value, and organic solvent recovery.

5、 Wastewater treatment:

1. Treatment of chromium containing wastewater with activated carbon:

Chromium is a large amount of metal raw material in electroplating. Hexavalent chromium in wastewater exists in different forms with different pH values. Activated carbon has a very developed microporous structure and a high specific surface area. It has a very strong physical adsorption capacity, and can effectively adsorb Cr (Ⅵ) in wastewater. There are a large number of oxygen-containing groups on the surface of activated carbon, such as hydroxyl (- OH), carboxyl (- COOH), etc., which have electrostatic adsorption function, and produce chemical adsorption on Cr (Ⅵ). It can be used to treat Cr (Ⅵ) in electroplating wastewater. The adsorbed wastewater can meet the national discharge standard. The results show that when the mass concentration of Cr (Ⅵ) in the solution is 50mg / L, pH = 3, and the adsorption time is 1.5h, the adsorption performance of activated carbon and the removal rate of Cr (Ⅵ) are the best. Therefore, the process of using activated carbon to treat chromium containing wastewater is the result of the physical adsorption, chemical adsorption and chemical reduction of Cr (Ⅵ) in solution by activated carbon. Activated carbon has stable adsorption performance, high treatment efficiency, low operating cost and certain social and economic benefits in the treatment of chromium containing wastewater.

2. Treatment of cyanide containing wastewater with activated carbon:

In industrial production, cyanide or by-product cyanide is used in wet extraction of gold and silver, production of chemical fiber, coking, synthetic ammonia, electroplating, gas production and other industries, so a certain amount of cyanide containing wastewater must be discharged in the production process. Activated carbon has been used to purify wastewater for quite a long time, and there are more and more reports about it_ The adsorption capacity of HCN on activated carbon is small, which is generally 3mgcn / GAC ~ 8mgcn / GAC, which varies with varieties, and is not cost-effective.

3. Treatment of wastewater containing mercury with activated carbon：

Activated carbon has the ability to adsorb mercury and compounds containing mercury, but its adsorption capacity is limited, so it is only suitable for the treatment of wastewater with low mercury content. If the concentration of mercury is high, it can be treated by chemical precipitation method first. After treatment, the concentration of mercury is about 1mg / L, which can reach 2-3mg / L when the concentration is high, and then it can be further treated by active carbon.

4. Treatment of phenol containing wastewater with activated carbon:

Phenolic wastewater is widely sourced from petrochemical plants, resin plants, coking plants and oil refining and chemical plants. The results show that the adsorption performance of activated carbon for phenol is good, the increase of temperature is not conducive to adsorption, so that the adsorption capacity is reduced, but the time to reach adsorption equilibrium is shortened. The amount of activated carbon and adsorption time have the best value. Under the acidic and neutral conditions, the removal rate does not change much. Under the strong alkaline condition, the phenol removal rate drops sharply. The stronger the alkaline condition, the worse the adsorption effect.

5. Treatment of methanol containing wastewater with activated carbon:

Activated carbon can adsorb methanol, but its adsorption capacity is not strong, so it is only suitable for the treatment of wastewater with low methanol content. The operation results show that the COD of the mixture can be reduced from 40 mg / L to less than 12 mg / L, and the removal rate of methanol can reach 93.16% - 100%. The quality of the effluent can meet the water quality requirements of the feed back to the desalted water system of the boiler.

6. Activated carbon treatment industrial drainage:

The application of activated carbon in industrial drainage can be divided into two situations: more industrial drainage and less industrial drainage. In these two cases, the use of activated carbon is different. In the case of more drainage, the drainage comes from a specific process, and the components contained in it rarely change frequently; on the contrary, in the case of less drainage, the components contained in the drainage change greatly, often different every day, even in different time periods of the day.

7. Domestic sewage treatment with activated carbon:

The importance of activated carbon in the treatment of domestic sewage is also an essential filter material in sewage treatment. Activated carbon is a kind of adsorbent widely used in domestic sewage treatment. At present, the discharge of domestic sewage in China is increasing at the rate of 5% every year. Therefore, the primary goal of solving environmental problems is to treat domestic sewage at present. Powdered activated carbon purification technology has been used to treat water for 70 years. Since the first application of powdered activated carbon in the United States to eliminate the smell of chlorophenol, the effective way to remove impurities in water is still activated carbon purification technology, and its purification effect has been listed first in many countries. At present, China has been looking for many ways to use waste as raw materials to prepare activated carbon. Walnut shell, bamboo, tobacco and other wastes have been used as raw materials to solve the problem of sewage treatment. Therefore, activated carbon purification technology is essential in sewage treatment. 　

6、 Sewage treatment:

1. The shell activated carbon is used for water purification and sewage treatment. Microfiltration is a kind of precision filtration technology. Its pore size range is generally 0.05-i0 / / m, between conventional filtration and ultrafiltration. It is driven by pressure to achieve the purpose of separation and concentration. There is no phase change and interface quality transfer, which is different from conventional filtration. Conventional filtration is generally divided into deep filtration and screen mesh filtration. The media used, such as paper, asbestos, glass fiber, ceramics, cloth, felt, etc., are all porous bodies with uneven pore shape. The distribution of pore size of Potamogeton crispus is wide, and its pore size can not be marked. During filtration, particles are trapped in the zigzag flow inside the media and are blocked. The increase of retention rate B6 pressure decreases, the media is thick, and the particles are widely distributed for general clearing Filter.

2. The filter medium used in microfiltration has a mesh like structure, which is formed by natural or synthetic polymer materials. The activated carbon in the shell has a porous structure. The pore size distribution is uniform.

Fruit shell activated carbon is widely used in the deep purification of drinking water, industrial water and waste water, industrial water purification and gas adsorption, such as power plant, petrochemical, oil refinery, food and beverage, sugar and alcohol production, medicine, electronics, fish farming, shipping and other industries. It can effectively absorb free chlorine, phenol, sulfur and other organic pollutants in water, especially mutagens (t HM) to achieve purification and odor removal. It can also be used for industrial tail gas purification, gas desulfurization, oil catalytic reforming, gas separation, PSA, air drying, food preservation, gas mask, disintermediation carrier, industrial solvent filtration, decolorization, purification, etc. Separation, purification and purification of various gases; recovery of organic solvents; decolorization, deodorization and purification of sugar, monosodium glutamate, medicine, alcohol and beverage; extraction of precious metals; catalysts and catalyst carriers in the chemical industry. The product has functions of decolorization, purification, impurity removal, deodorization, odor removal, carrier, purification, recovery, etc.
8、 Precautions:

1. In the process of transportation, the shell activated carbon should not be mixed with hard materials, and should not be stepped on or stepped on, so as to prevent the carbon particles from crushing and affecting the quality.

2. Storage should be stored in porous adsorbent, so in the process of transportation, storage and use, it is absolutely necessary to prevent water immersion, because after water immersion, a large amount of water is filled with active voids, making it useless.

3. In order to prevent tar substances from being brought into the activated carbon bed in the process of use, so as not to block the gap of activated carbon and make it lose the adsorption effect. It is better to have a decoking device to purify the gas.

4. During storage or transportation, the fire-proof activated carbon shall not be in direct contact with the fire source, so as to prevent ignition. During regeneration of the activated carbon, oxygen shall be avoided and regeneration shall be complete. After regeneration, the activated carbon must be cooled down to below 80 ℃ with steam, otherwise the temperature is high, and in case of oxygen, the activated carbon will ignite.
