water purification and water treatment activated carbon have? According to the kinds of activated carbon production of raw materials can be divided into wood and coal carbon. Use wood, wood, shells, plant fiber materials such as activated carbon made of wood charcoal; Another type of use, peat, lignite, bituminous coal and bituminous coal, anthracite coal activated carbon is made qualitative charcoal. In terms of particle size, there are powder charcoal ( Particle size below 200 mesh) And particulate carbon ( Particle size in 1. 6 ~ 3. 2mm) If points according to the use, catalyst carrier, recycling, carbon adsorption desulfurization decoloring carbon and water by activated carbon. Finished product activated carbon, its appearance is black solid matter, odourless tasteless, main component carbon accounted for more than 80%, the rest of hydrogen, oxygen, iron, sulfur, phosphorus, calcium, etc. As well as the moisture and ash content. It does not dissolve in water and organic solvents, various types of activated carbon are composed of microcrystalline carbon sponge material. Water with activated carbon, generally using anthracite as raw material, after breaking the carbonization and activation was water vapor directly, appearance is amorphous particles, particle size is 2 & # 12316; 4 mm, in the liquid phase in low concentration and high concentration of organic matter, have high adsorption capacity, such as adsorption of phenol is 150 mg/g ( When the water of phenol content = 300 mg/L) , it has developed pore structure, filter hole is developed, and so on of macromolecular organic matter in coal chemical industry, petroleum chemical industry waste water is better than that of general activated carbon adsorption. By the manufacturing process is simple, reactants, so the cost is low, there is a better mechanical strength, as well as general granular carbon, can endure high temperature regenerative for many times, low-cost adsorbent is promising. On feed processing on the other hand, people still like to use woodiness active carbon, wood activated carbon adsorption capacity is large, with high iodine adsorption value and methylene blue adsorption value, the current production of household or group with water purifiers, generally loading wood activated carbon.
