Screening of efficient degrading strains and its application in paper-making wastewater

摘要

To improve the biological treatment effect of paper-making wastewater, the screening of strains degrading wastewater and its application were carried out. Twelve strains were separated from biological aerated filter; two efficient degrading strains (D1, E2) were screened based on the degradation rate of CODcr. The D1, E2 were selected to apply in wastewater treatment experiment and the results showed that the removal rate of CODcr were 78.4%, 59.1% respectively, they displayed good prospects in paper-making wastewater treatment.
