- Abstract:
- A three-dimensional rotating biological contactor (3D-RBC) sewage treatment station was built in public private partnership (PPP) mode to treat the rural domestic sewage in south China. After stable operation, the effluent COD, NH3-N, TN and TP are 38.1 mg/L, 2.7 mg/L, 12.8 mg/L and 0.34 mg/L respectively, which meet the first level A criteria specified in the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002). This project uses three units of RBC with start and stop operation, without aeration, cover an area of about 60 m2. The power consumption of the RBC is 0.108 kW·h/m3 sewage, and the investment of this project is about 2 million yuan. Engineering practice shows that the 3D-RBC has the advantages of small floor area, low operation cost, simple and stable operation for rural domestic sewage treatment.
