Abstract

The article shows that purification of water of 2-nitrophenol the term of the effective operation of biological activated carbon is increased by 1–1.5 month in fulfilling periodic offline aeration of the sorbent (4–7 days) with addition of nutrients. In this case 60–80% of restored pores volume was freed of products of vital activities of microorganisms.
