摘要:-
青島某全地下污水處理廠設計規模為4×104 m3/d，廠區占地為1.31 hm2，采用曝氣除油沉砂池+精細格柵+生物池 +MBR 工藝。進水以生活污水為主，設計出水水質同時滿足《城鎮污水處理廠污染物排放標準》（GB 18918—2002）一級A標準、《城市污水再生利用 景觀環境用水水質》（GB/T 18921—2002）中的娛樂性景觀環境用水標準、《青島市環境保護局關于明確2015年省控河流斷面水質改善目標的函》中相關要求。廠區用地面積較小且呈不規則狀，為保證生物池水力停留時間滿足處理要求，本次設計生物池有效水深為8.5 m。實際運行表明，出水水質完全達到了設計目標，其設計經驗可供其他類似工程參考。
Abstract:-
The design scale of an underground MBR wastewater treatment plant in Qingdao was 4×104 m3/d with the area coverage of 1.31 hm2. The combination treatment process of aeration oil removal sedimentation tank+fine grille+biological treatment tank+MBR was adopted. Domestic sewage was the main part of influent. The design effluent quality was required to meet the relevant requirements of the first class A standard of Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002), the recreational landscape environment water standard in the Reuse of Urban Recycling Water—Water Quality Standard for Scenic Environment Use (GB/T 18921-2002), and the Letter of Qingdao Environmental Protection Bureau on Clarifying the Water Quality Improvement Target of Provincial River Section in 2015. The land of the plant was small and irregular. In order to ensure the sufficient hydraulic retention time of the biological tank for the treatment requirements, the effective depth of the biological tank in this design was 8.5 m. The actual operation showed that the effluent quality had completely reached the design goal. Its design experience could be used as a reference for other similar projects.
