Chemical Regeneration of Biological Activated Carbon in Removing Nitrophenol

摘要

Investigated are changes of the porous structure of biological activated carbon in filtration and after chemical regeneration. It is shown that 71–84 vol % of recovered pores were blocked by the products of microbe vital activity. Alkaline treatment of the bed of biological activated carbon (during several days) makes it possible to prolong efficient nitrophenols removal from water by 10–11 months.
