- Application of Rotating Biological Contactors in Reconstruction and Expansion Project of a Municipal Wastewater Treatment Plant
摘要:- 平涼市某污水處理廠原設計規模5.0×104 m3/d，采用傳統A2/O+深度處理工藝,本次擴建后規模達到8.5×104 m3/d。針對廠區用地
緊張、進水總氮濃度高等問題，缺氧區采用生物轉盤強化系統的脫氮性能，好氧區改造為限氧曝氣區，并新建初沉池以確保出水指標達標。實際運行數據顯示，在低溫、低碳氮比條件下，出水水質可穩定達到《城鎮污水處理廠污染物排放標準》（GB 18918—2002）的一級A標準。該工程總投資為10 793.17萬元，直接運行成本為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.
