Using air - lift loop reator as aeration device, the effectiveness of treatment for petrochemical wastewater and the effect of various operation parameters to wastewater treatment are studied. The result shows, air - lift loop reator can used to biological treatment of petrochemical wastewater, the water exit reaches the protrochemical wastewater national secondary emission standard, the activated sludge after ac- climated appear rich microbial morphology, the degradation reaction process accord with first order reac- tion kinetics model. The activated sludge concentration and hydraulic retention time has important influ- ence to degradation reaction, and existing a optimal operation parameters. Compared with traditional treat- ment, the air - lift loop reactor has advantages such as high aeration efficiency, good treatment effect, short dwell time, small occupation area, etc. It is worthy of developing feasibility study of industrial scale.
