Activated carbon adsorption is a physical process, it can be also used high-temperature steam impurities used within the desorption of activated carbon, and to restore the original of the activity, in order to achieve the purpose of re-use, it has obvious economic benefits. Activated carbon regeneration after its use can still be reused and recycled continuously. [Activated carbon regeneration technology development With the increasingly wide range of applications of activated carbon, activated carbon recovery began to get people's attention. If the spent activated carbon can not be recovered, in addition to waste water treatment cost per ton will increase from 0.83 to 0.90 yuan, it will also cause secondary pollution to the environment. Thus, regeneration of activated carbon has particular importance. [Traditional methods] 1.1 activated carbon regeneration heat regeneration thermal regeneration of activated carbon regeneration process is the most widely used method, the industry's most mature. Activated carbon treatment of organic wastewater in the regeneration process, when heated to a different temperature according to changes in organic matter, is generally divided into drying, high-temperature carbonization and activation stages. In the drying stage, mainly to remove volatile components on activated carbon. High temperature carbonization stage is a part of the organic matter adsorbed on the activated carbon boiling, vaporization desorption, part of organic matter decomposition reaction of small molecule hydrocarbon desorbed residual component left in the activated carbon pores to become "fixed carbon." At this stage, the temperature will reach 800 [iodine value recognition of powdered activated carbon] in the case of non-detection devices to identify how simple the level of activated carbon adsorption value it? Here are a few easier ways for reference: 1, provided by the manufacturer directly to see indicators 2, see Volume: To improve the performance of activated carbon adsorption, and only as much as possible in the manufacture of activated carbon pore structure, the more porous, charcoal more crisp, the relative density of the more light, so good on the activated carbon will be relatively light touch, in the case of the same weight packaging, good performance will be larger than the poor quality of many of activated carbon activated carbon volume. 3, see bubbles. A small active carbon into the water, because the water of osmosis, the water will gradually immersed in the pore structure of activated carbon, forcing air out of the pores, resulting in a series of very small bubbles in the water line pulled out a small bubble, It will also issue the slightest sound of bubbles, very interesting. This phenomenon occurs the more intense the longer the duration, activated carbon adsorption, the better. 4, see decolorization. Another performance of activated carbon adsorption capacity is bleaching ability, activated carbon can become light colored or colorless liquid magical ability, which is actually the reason is because the activated carbon adsorption of the dye molecules in the colored liquid caused. Because of this feature activated carbon is widely used in the sugar industry in the field of brown sugar production process becomes. Take two transparent glass, in a cup of water into pure, then dropped a drop of red ink (where you can use any kind of easy to observe, but do not change the properties of water pigment can be, for example, blue ink, color ink printers, but you can not use the ink and the carbon ink), stir after half colored water poured another cup reserved control sample. The water samples were compared with the comparative activated carbon into the colored water, and the number should reach half of water or more, this effect will be more obvious, to stand for 10-20 minutes under the same conditions, the stronger the effect described bleaching activated carbon adsorption the better.
