Abstract:

The application of air floatation-A/O technology to the treatment of oil-bearing effluent has been described in detail.After the six-year experience of running, it show S^2-, CODCr, and oil of the effluent are 0.28 mg/L, 80.16mg/L and 4.84mg/L respectively, which reaches the discharged standard, on condition such as S^2- 14.82mg/L, COD_Cr 1 244.5mg/L and oil 184.89mg/L. The results of treatment technology show that it has two advantages, high running stability and excellent treatment effect.
