3D-RBC立体结构生物转盘工艺处理村镇生活污水
- Title:
- Treatment of Rural Domestic Sewage with 3D-RBC Process
- 摘要:
- 采用PPP模式新建了3D-RBC立体结构生物转盘工艺污水处理站,处理南方某村镇生活污水。稳定运行后出水COD为38.1 mg/L,NH3-N为2.7 mg/L,总氮为12.8 mg/L,总磷为0.34 mg/L,达到《城镇污水处理厂污染物排放标准》(GB 18918—2002)的一级A标准。该工程采用3台生物转盘设备,仅需启动、停止操作,无需风机曝气,占地约60 m2,生物转盘电耗为0.108 kW·h/m3。该工程工艺部分投资约200万元。工程实践表明,采用3D-RBC立体结构生物转盘工艺处理农村生活污水,具有占地面积小、运行成本低、操作简便、运行稳定等特点。
- 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.
