Isolation of the Strains for the Degradation of APMP Pulping Effluent

Abstract:

In this paper, the strains were separated from pulping effluent and aerobic sludge. The plate separation was used in process of separation and purification. During the selection process, six different strains were obtained according to the differences among the COD removal rates, growth curves, colony feature and characteristics of bacteria. The results of the degrading experiment of pulping effluent showed that W₃ and S₂ had better performance among all of strains. COD of pulping effluent was decreased from 6960 mg/L to 3300 mg/L by W₃, the removal rate is 51.87%. When the strain S₂ was used for the degradation of pulping effluent, COD value dropped from 6960 mg/L to 2860 mg/L, and the removal rate is 55.03%.
