With the extensive application of activated carbon, the regeneration and reuse of activated carbon has been paid more and more attention.yrdcarbon
If the used activated carbon cannot be recycled, it will not only cause great waste of resources and economic losses, but also cause secondary pollution to the environment.
Activated carbon after use is discarded or recycled after recycling has become an important symbol reflecting the level of a national activated carbon industry.
In recent years, the major activated carbon producers in the world, such as the United States and Japan, have turned their attention to the regeneration mechanism of activated carbon and the development of new regeneration technology.
Activated carbon regeneration will be saturated adsorption of various pollutants activated carbon through special treatment, so that the activated carbon to recover most of the adsorption capacity, in order to be re-used in the adsorption process.
The key factors influencing the regeneration of activated carbon are the type of activated carbon and the adsorption substance.activated charcoal powder wholesale
At present, the domestic and foreign activated carbon regeneration methods that have been formed or basically formed mainly include thermal regeneration method, wet oxidation regeneration method, electrochemical regeneration method and forced discharge regeneration method.
Through the comparison of the mechanism and technical characteristics, this paper chose the forced discharge regeneration technology to study two different kinds of carbon.
Paper detailed study the mandatory discharge of recycling technology of different activated carbon adsorption saturation effect, different age, different types of activated carbon, and the same saturation regeneration effect comparison before and after cleaning as well as the different saturated carbon regeneration after the tannic acid, humic acid, bisphenol A and dimethyl phthalate adsorption ability, finally, the performance test method of activated carbon were studied.
