Abstract
Pilot-scale anaerobic and aerobic treatment in a two-step bioreactor was performed for the removal of pollutants from pulp and paper mill effluent. After seven days of anaerobic treatment, colour (45%), lignin (60%), COD (26%) and adsorbable organic halogen (AOX) (20%) were reduced. The anaerobically treated effluent was then treated in a bioreactor in the presence of a fungal strain (Aspergillus fumigatus) or a bacterial strain (Pseudomonas ovalis). The results of this study indicated a reduction in colour (76% and 56%), lignin (78% and 68%), COD (85% and 78%) and AOX (70% and 82%) by Aspergillus fumigatus and Pseudomonas ovalis respectively.
