生物转盘工艺在城镇污水处理中的工程应用

宁波白峰污水处理站一期工程采用生物转盘的核心处理工艺,转盘直径为4 m,是目前国内直径最大的生物转盘,污水处理能力为0.6×10^4 m^3/d,出水水质执行《城镇污水处理厂污染物排放标准》(GB 18918—2002)的一级A标准。介绍了主要构筑物及设备的设计参数,并对运行效果进行了分析,此外,针对生物转盘工艺在不同水力负荷情况下的处理能力进行了分析,结果显示,高、低水力负荷情况下生物转盘的处理能力无太大变化。

Application of Rotating Biological Contactors in Municipal Wastewater Treatment Project

The first phase of Ningbo Baifeng wastewater treatment station adopted the treatment process of rotating biological contactors.The diameter of the rotating disc was 4 meters,which was currently the largest rotating biological contactors in China.The wastewater treatment capacity was 0.6×10^4 m^3/d.The effluent quality was in accordance with the first level A criteria specified in the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant(GB 18918-2002).The design parameters of main structures and equipments,operation performance were introduced.The treatment capability of rotating biological contactors process under various water load was analyzed,the processing capacity of rotating biological contactors was stable under either high or low influent load.
