Study on the Harm of Waste Activated Carbon and Novel Regeneration Technology of it

Abstract Activated carbon is widely employed as an adsorbent in environmental protection, food, medicine, chemical industry, energy and other fields due to its good physical and chemical properties and low price. However, the resulting large amount of saturated activated carbon is easy to release harmful substances in the high temperature environment. Even if the saturated activated carbon is treated with harmless regeneration technology, it may lead to secondary pollution owing to improper disposal. Therefore, on the basis of summarizing the traditional methods of activated carbon regeneration, combined with the research progress in the laboratory, frontier progress of new activated carbon regeneration technology are elaborated in recent years in this paper, and the development direction of activated carbon regeneration technology are also presented in the end of the paper.
