瀘州某在建酒業(yè)園區(qū)地下污水處理廠總規(guī)模為2×10⁴ m³/d，設計出水除TN濃度為10 mg/L外，其余主要出水水質指標均滿足《地表水環(huán)境質量標準》（GB 3838—2002）中地表水Ⅲ類水標準，處理出水排入廠外小溪溝。污水廠采用全地下式建設型式，以減小占地，降噪防臭。地面打造景觀公園，箱體內部組合處理構筑物形成處理單元，緊湊布局降低成本。采用Phoredox+MBR工藝作為核心生物處理工藝組合，保障可降解有機物、TN的有效去除；采用多級流動床活性焦吸附塔+砂濾池作為深度處理工藝組合，保障難生化有機物、色度等污染物的有效去除。結合地下箱體特點采用機械通風與自然通風相結合的通風系統(tǒng)，以及消火栓系統(tǒng)結合滅火器的消防系統(tǒng)，并針對斷電和異常水質水量等情況設計應急處理方案。

The total scale of underground wastewatertreatment plant in a liquor industry park under construction of Luzhou was 20 000 m³/d. The effluent TN was required as 10 mg/L, the other main indexes were required to meet the surface water class Ⅲ standard in the Environmental Quality Standards for Surface Water (GB 3838-2002). The effluent was discharged into the creek outside the plant. The wastewater plant adopted the underground construction mode,which reduced the land occupation, noise and odor. With a landscape park on the ground, the wastewater plant combined treatment structures inside the box forms treatment unit, compect layout reduced cost. Phoredox+MBR process was used as the core biological treatment process to ensure the effective removal of degradable organics and TN. Multistage flow bed activated coke adsorption tower+sand filter was used as the advanced treatment process to ensure the effective removal of difficult biochemical organics, chroma and other pollutants. Combined with the characteristics of underground tanks, the ventilation system combining mechanical ventilation and natural ventilation was adopted.Furthermore, the firefighting system combining fire hydrant system and fire extinguisher was adopted. The emergency treatment plan was designed according to the situation of power failure and abnormal water quality and quantity.
