Biological Post-Treatment of Anaerobically-Treated Black Liquor Spills From Kraft Pulp-Mill

摘要

Previous research has shown that anaerobic treatment in biological fluidized bed reactors of kraft black liquor spills effluents (DL) is an effective alternative. However, important concentrations of recalcitrant organic matter and color still remain in the anaerobic effluent (AnE). Aerobic bacterial post-treatment was ineffective, while adsorption onto activated carbon removed both color and organic matter, but at potentially unfeaible costs.
