摘　　要：根据胜利油田低渗透区块某联合站的污水水质特征和回注水水质要求,采用溶气气浮/三级过滤(粗滤、精滤、超滤)处理工艺,处理水量为400 m3/d。运行一年多来,出水水质稳定,达到《碎屑岩油藏注水水质推荐指标标准及分析方法》(SY/T 5329—94)的A1级标准,环境效益和经济效益显著。Based on the characteristics of wastewater quality of a combined station in the low permeability reservoirs of Shengli Oilfield and the quality criteria of reinjection water, the dissolved air flotation （DAF）/three-stage filtration （rough filtration, fine filtration, uhrafihration） process were used to treat the wastewater. The treatment capacity is 400 m^3/d. The effluent quality reaches the A1 criteria specified in the Recommendation Standard and Analysis Method for the Clastic Rock Reservoir Injection Water Quality （SY/T 5329 -94 ） even if the system has been run for more than a year. Moreover, this process has many advantages such as stable effluent quality, obvious economic benefit and high environmental benefit.
