- Abstract:
-
The commissioning and operation of EBAF biological aerated filter (BAF), which is used as the main treatment process in the Nanning Shuitangjiang Sewage Treatment Plant, are introduced. The commissioning and operation results show that under the condition of low influent C/N ratio, it took only 50 days for EBAF with higher design filtration velocity and load to complete the process of biofilm attachment and acclimation. After dynamic control of carbon source dosage and nitrate liquid return ratio, the effluent indicators can meet the first level A requirements specified in Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant(GB 18918-2002). The rapid start-up and stable operation of the BAF sewage treatment plant can provide new process ideas and commissioning experience for the treatment of low-concentration domestic sewage in southern areas.
