Abstract

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 COD_cr. The D₁, E₂ were selected to apply in wastewater treatment experiment and the results showed that the removal rate of COD_cr were 78.4%, 59.1% respectively, they displayed good prospects in paper-making wastewater treatment.
