Abstract

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