摘　　要：探索石化企业高盐化工废水采用高盐难降解有机废水新型催化氧化耦合生物膜法最佳工艺路线及相应最佳控制条件。以催化氧化工艺耦合生物膜方式及氧化剂投加量为影响因素,研究不同工艺及氧化条件处理对出水水质影响。结果表明,采用一级氧化+生物膜法+二级氧化的工艺处理高盐难降解有机废水,最终出水COD浓度可稳定在50 mg/L以下,出水总氮、氨氮稳定达标。To explore the optimum process and condition of high salinity hard-degradable organic wastewater from petrochemical enterprises by high salinity hard-degradable organic wastewater catalytic oxidation-biological membrane combined process.Catalytic oxidation and biof ilm coupling mode and dosage of oxidant added were taken as the influencing factors to study effects of different processes and oxidation conditions on effluent quality.The main conclusions were got from the experiment as follows:the process of high salinity hard-degradable organic wastewater with pretreatment oxidation+biof ilm process+secondary oxidation,the COD of the final effluent can be stable below 50 mg/L,the TN and NH3-N in the effluent reached the standard steadily.
