Cooxidation of Benzo(a)pyrene and Phenols on Activated Sludges
In the presence of the cancerogenic benzo(a)pyrene (4 × 10−7 mole/1) the rate the of biochemical oxidation of phenols and a mixture of oil‐shale alkylresorcinols (5 × 10−5 mole/1) on activated sludges adapted to these phenols is reduced up to 30%. The oxidation of benzo(a)pyrene occurs at a high rate, the rate constant on both sludges being 6.8 × 108 mole/1 · sec and exceeds the index of the processes of its selfpurification by two orders.
The high efficiency of the biooxidation of benzo(a)pyrene is retained at a repeated use of the same biomass, thus no additional regeneration being needed.
Some products of the, biooxidation of benzo(a)pyrene, such as 1,6‐ and 3,6‐quinone, derivatives of chrysene and naphthalene, are identified.
