Embodiment Construction
[0022] A certain urban sewage treatment project requires the effluent to reach the level of 8mg / L total nitrogen and 3mg / L ammonia nitrogen after transformation, but the hydraulic retention time of the whole process is only 8.7 hours. It is impossible to meet such strict water discharge requirements.
[0023] According to the process of the present invention, the process is transformed, and the existing common sedimentation tank is adopted, and the main operating parameters are as follows.
