- Abstract:
-
The commissioning process of five- stage Bardenpho in a wastewater treatment plant of Hangzhou was summarized. The full utilization of carbon source in raw water and the control of biological phosphorus removal were analyzed. By means of the bypass operation of primary sedimentation tank and the strict control of dissolved oxygen and internal reflux ratio in the aerobic section, nitrogen and phosphorus were removed in the biological tank as well as the carbon source is saved. The effluent quality of five-stage Bardenpho can meet the first level A criteria specified in Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant(GB 18918-2002).
