Analysis of the main mechanism of activated carbon
Added:2017-09-13     Views:

Activated carbon is a kind of hydrophobic adsorbent made of carbon containing material as raw material and carbonized and activated at high temperature. Contains a lot of microporous activated carbon, with a huge surface area, can effectively remove the color, smell, can remove most of the organic pollutants in water two and some inorganic substances, including some toxic heavy metals. The factors that affect the adsorption of activated carbon are: the characteristics of activated carbon, the characteristics and concentration of the adsorbent, the pH value of the wastewater, the content of suspended solids, contact system and operation mode, etc..
Activated carbon can effectively adsorption of chlorinated hydrocarbons, organic phosphorus and carbamate pesticides can absorb benzene ether, nitro chlorobenzene, naphthalene, phenol, phenol, xylene, ethylene, DDT, aldrin, and many benzene sulfonic acid esters and aromatic compounds. Two grade water also contains organic matter adsorbed by activated carbon, such as intermediate material degradation of protein, organic matter than the original more difficult by the adsorption of activated carbon, activated carbon removal capacity of THMS is relatively low, only reached 23-60%. Active carbon adsorption and other methods combined with the ozone activated carbon method, coagulation activated carbon adsorption method, Habberer process, activated carbon adsorption cycle of indigenous diatom, activated carbon increased obviously, reduce the dosage, treatment effect and greatly improve the range. This is the mechanism of the action of activated carbon in Ningxia.
