title: [The kinetics of biological treatment of bleaching liquor from straw pulp process].
abstract: The batch test of oxygen uptake rate (OUR) measurement was used to simulate biochemical reaction process in aerobic reactor treating bleaching liquor from straw pulp process. Lawrence-McCarty kinetic model was used to analyze the biochemical reaction process. The kinetic equation of bleaching liquor biological treatment, v = 0.72 S/(60.43 + S), was deduced from results of the OUR experiment and the bench experiment. The specific substrate degradation rate estimated by the kinetic equation was higher than that of practical wastewater treatment plant. The phenomenon was attributed to the decrease of activated sludge activity caused by cellulose suspended solid accumulation in aerobic reactor of practical plant.
