摘要:- 西咸新區某污水處理廠提標擴建工程設計規模為5×104 m3/d，出水水質執行《地表水環境質量標準》（GB 3838—2002）準Ⅳ類標準。該工程二級處理新增1×104 m3/d改良AAO+矩形周進周出二次沉淀一體式組合池，三級處理新建臭氧接觸池及V型濾池，出水采用紫外線消毒，總投資為8 058.93萬元。提標擴建工程投入運行后，出水水質穩定達到準Ⅳ類標準。
Abstract:- The design capacity of a wastewater treatment plant upgrading and expansion project in Xixian New Area is 5×104 m3/d, and the effluent water quality is in accordance with the quasi-Ⅳ standard of Environmental Quality Standards for Surface Water (GB 3838—2002). The integrated process including modified AAO and secondary sedimentation tank with peripheral water inlet and outlet is adopted in secondary treatment, while ozone contact tank and V-filter are newly built in tertiary treatment, and the effluent is disinfected by ultraviolet light. The total investment is 80.589 3 million yuan. After operation, the effluent quality can stably meet design standard.
