Kinetics of organochlorine removal from bleached kraft pulp mill effluent during biological treatment.

摘要

he following research project was undertaken to investigate the biodegradation of organochlorine in a bleached kraft pulp mill effluent and to develop a kinetic espression for AOX removal. Batch kinetic studies were conducted with variable AOX (6.0-35 mg Cl/L) and biomass (400-3050 mg VSS/L) levels, using whole mill effluent (about 70% ClO;Comparison among four kinetic models showed that the AOX removal kinetics was best described by a recalcitrant first order model:
