As the main pillar of the national economy, nut shell activated carbon is playing an increasingly important role in modern society. granular activated carbon manufacturers Mainly used in sugar, medicine, monosodium glutamate, water treatment, solvent recovery, food and beverage purification, air purification, desulfurization, carrier, gold extraction, anti-virus, anti-virus clothing, semiconductors, etc.
Since the 21st century, China's annual production of activated carbon has exceeded 200,000 tons, making it one of the most important producers in the world. By 2010, domestic consumption of activated carbon from nut shells is expected to reach about 120,000 tons, which is also one of the largest consumer markets in the world.
However, according to the editor of columnar activated carbon, compared with developed countries, China's activated carbon industry still has a big gap, especially in terms of production technology, production equipment, product quality, and after-sales service. The gap is obvious.
Coal-based activated carbon used for water purification is mainly used for filling, dechlorination, oil reduction and deep purification of municipal drinking water, purified water, distilled water, ultrapure water and other manufacturing equipment.
Activated carbon and graphite are similar to graphite structural substances. Chemically speaking, activated carbon is composed of many carbon hexagonal rings, which results in a strong specific surface area and porous structure of activated carbon, which has the function of physical adsorption. It is often said that the adsorption of activated carbon is not the self-absorption of activated carbon, but the atomic or lattice defects at the edge of the microcrystalline plane layer. Displacements and faults have active points, so they are full of unpaired atoms and electrons, so they form chemical adsorption under certain conditions. There are several specific reasons for the smell of sewage:
1. Water with high iron content not only smells of rust, but also produces an odor due to excessive Fe ++ oxidation by some bacteria;
2. Water with high organic content is easy to be eroded, breed mold and produce rotten taste. Water with excessive phosphorus is easy to produce algae and produce a fishy smell of algae. Water rich in sulfides can produce an unpleasant smell. Due to the high mud content, the Yellow River water will produce a muddy smell.
Activated carbon adsorption is one of the effective methods to remove trace organic substances in drinking water. Remove the color, smell and taste in the water is particularly obvious.activated carbon wanyang In the part of the annual study, it was found that the combination of water purification activated carbon and activated carbon can completely remove the odor in the water. In recent years, due to serious environmental protection measures, activated carbon raw materials have flourished.
