| Abstract: | Microorganisms in the aerobic sludge were cultivated on the lB medium. 16 strains were selected according to their colony characteristics, and then, their biodegrability of Kraft pulp bleaching effluent were analyzed. The results show that 8 strains can degrade Kraft pulp bleaching effluent effectively, among of them, the stain BKPE-11 is the best, which can remove COD in effluent of 67.46% during 64 hours. The growth curve and the degradation kinetics of BKPe-11 in bleaching effluent were also studied, and the dynamics equation was established. |
