摘要: Abstract A laboratory-scale rotating drum biological contactor (RDBC) with immobilized white rot fungus Irpex lacteus was used to decolorize synthetic wastewaters containing the azo dye Reactive Orange 16 (RO16) and anthraquinone Remazol Brilliant Blue R (RBBR). Two particulate packings were immobilize fungus: AL-Schwimmbett Medium 100L that appeared not be convenient, because of a low adhesion fungal mycelium particles, oak wood cylinders supported formation thin layer biofilm on surface particles resulting faster degradation dyes in comparison particles. In batch decolorization experiments at initial concentration 100 mg dm -3 it took from 4 5 hours for RBBR 21 hours RO16 get 85% decolorization. continuous experiment high inlet mass flow rate (0.5 mg min -1 ) degree achieved just 20%. Activities enzymes manganese-dependent peroxidase, lignin peroxidase laccase also monitored during experiments.
