Abstract
|
|
|
|
The biological treatment by a mixed culture GE2 immobilized on activated carbon was investigated with a phenolic resin industrial wastewater containing 41,000 ㎎/ℓ of phenol and 2,800 ㎎/ℓ of formaldehyde. At a dilution of 20 times with aerated tap water, influent and effluent COD_Mn were 4,587 ㎎/ℓ and 46 ㎎/ℓ, that is, COD, removal efficiency was 99.0%. At this time, phenol and formaldehyde concentration of the effluent were 1.24 and 6.80 ㎎/ℓ, indicating removal efficiencies of 99.9 and 94.1%, respectively.
