At present, the organic pollution of drinking water source is relatively serious. The organic pollutants themselves are not only highly toxic, but also may generate halogenated disinfection by-products (DBPs) after chlorination disinfection. Meanwhile, the existence of organic compounds will reduce the biological stability of drinking water and lead to the secondary reproduction of microorganisms in the pipe network. Therefore, it is important to reduce the content of organic pollutants in drinking water. Conventional water treatment process has low removal efficiency for organic pollutants, so it is imperative to seek economic and efficient treatment technology. On the basis of giving full play to the advantages of ozone oxidation in the removal of organic matter, ozone catalytic oxidation technology can induce the formation of hydroxyl radical (·OH) with high oxidation ability, which can effectively remove trace organic pollutants in water and reduce the content of ozone oxidation by-products. Therefore, it is a drinking water treatment method with great application prospect.granular activated charcoal
Laboratory studies have shown that ceramic honeycomb activated carbon catalytic ozone oxidation technology and removal of trace organic matter in water has more obvious advantages, but the catalytic oxidation and active carbon process characteristics to be in-depth study, therefore the pilot was investigated through honeycomb ceramic catalytic ozonation and activated carbon catalytic ozonation and activated carbon filter combination process operation characteristics.Activated carbon is a non-polar adsorbent, mainly used for the removal of pigment and the separation of water-soluble components such as amino acids, sugars and some water-soluble glycosides, he is one of the main methods for the separation of water-soluble components. Activated carbon column chromatography is characterized by easy raw material source, low price, large sample load, good separation effect, suitable for mass preparation separation. However, due to the production of activated carbon raw materials, preparation methods and specifications are different, its adsorption force is not as easy to control as silica gel, alumina. Up to now, there is no ideal method to determine the level of adsorption, which limits the wide application of activated carbon column chromatography.coal activated carbon supplier
