摘要
用生物法处理石西油田采出水(简称采出水),通过中试试验考察了采出水的处理效果。试验结果表明:处理水量为2.5 m^3/h、进水中COD小于600 mg/L时,出水中COD一般稳定在90～120 mg/L,COD去除率一般在70%以上;出水中挥发酚、油质量浓度分别为0.007～0.219,0.1～1.8 mg/L,达到GB 8978—1996《污水综合排放标准》中的二级标准。对油去除效果较好的SYB,SYG,SYJ均为杆状单生鞭毛铜绿假单胞菌。
The produced water in Shixi oilfield was treated by biological process. The treatment effects were examined by pilot tests. The results show that： When the quantity of produced water is 2.5 m^3/h and the influent COD is less than 600 mg/L, the effluent COD is 90 - 120 mg/L, and the COD removal rate is above 70% ; The mass concentrations of volatile phenol and oil in the effluent is 0.007 -0. 219 mg/L and 0.1 -1.8 mg/L respectively, which can meet the secondary grades of the Integrated Wastewater Discharge Standard GB8978--1996; The strains SYB, SYG, SYJ, which have better effects on oil removal, are all Pseudomonas aeruginosa strains with rod shape and single flagellum.
