Pilot- scale study was made on petrochemical salty sewage by adopting micro- bubble pure - oxygen aeration process with special aeration tubes, aiming at the problems of low oxygen - charging ability and self - stopping phenomenon existed in the surface aeration machine of ethylene sewage treatment farm in Qilu Branch Co. which influenced the stable running and treatment ability of the oxygen aeration pool. The results showed the usage rate of oxygen reached 76%, the decomposition rate of COD exceeded 85%, stable treatment effect was obtained. This research laid the foundation for the reform of industrial device.
