Screening of Efficient aerobic denitrifiers in the
Urban water utilization project
Abstract: As the surface water quality deterioration and the development of industry and agriculture increased demands on water resources. Water resources become increasingly prominent. Comprehensive utilization of urban water is an effective measure to alleviate the conflict of water resources. But one of the biggest problems of water reuse is facing the ammonia concentration in control, it must be effectively removed . And with the problem of eutrophication of surface water and the improving of environmental quality standards. nitrogening has become the improvement issues in the field of water quality and water pollution control. Now, a lot of theories and techniques of the biological nitrogen removal have been reported,but the denitrification of the source water has been studied little This article describes that we have found five denitrifying bacteria,whitch has the high efficiency of TN removalling. And the TN removalling are from85%-93%.And we have preserved these five strains.
