- Application of Rotating Biological Contactors in Reconstruction and Expansion Project of a Municipal Wastewater Treatment Plant
摘要:- 平凉市某污水处理厂原设计规模5.0×104 m3/d，采用传统A2/O+深度处理工艺,本次扩建后规模达到8.5×104 m3/d。针对厂区用地
紧张、进水总氮浓度高等问题，缺氧区采用生物转盘强化系统的脱氮性能，好氧区改造为限氧曝气区，并新建初沉池以确保出水指标达标。实际运行数据显示，在低温、低碳氮比条件下，出水水质可稳定达到《城镇污水处理厂污染物排放标准》（GB 18918—2002）的一级A标准。该工程总投资为10 793.17万元，直接运行成本为0.72元/m3。
Abstract:- The original design capacity of a wastewater treatment plant in Pingliang City is 5.0×104 m3/d， using the traditional A2O+advanced treatment process, the capacity of this expansion reaches 8.5×104 m3/d. In view of the shortage of land and high concentration of influent total nitrogen, the anoxic zone adopts rotating biological contactors to enhance the denitrification performance, the aerobic zone is transformed into limited aeration zone, and a new primary sedimentation tank is built to ensure the design effluent target. Actual operation results showed that effluent quality stably met the first level A criteria specified in the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002) under low temperature and low C/N ratio. The total investment of the project was 107.931 7 million yuan, and the direct operation cost was 0.72 yuan/m3.
