摘　　要：采用二段A/O工艺对预处理后酞菁蓝生产废水进行深度处理,在实验室内研究了该生化工艺的特性。随着水力停留时间的增加,一级和二级出水的水质明显改善;利用厌氧段内水解酸化污泥,可显著提高废水的可生化性。出水NO3--N的浓度指示了生化系统的反硝化效果,试验确定最佳混合液回流比为2.5。当进水CODCr和NH3-N浓度分别为1 500和140 mg/L时,生化处理系统可有效运行。研究表明,二段A/O生物处理系统能够应用于经过预处理后的酞菁蓝生产废水的后续处理。In the laboratory, the characteristics of pretreated wastewater from pathalocyanine production by twophase A/O process is studied. As the hydraulic retention time increases, the effluent quality of the first and the second phase is improved. The biological decomposition of the wastewater is enhanced by utilizing the hydrolyzed acidification sludge in the anoxic zone. The denitrification effect is indicated by the effluent NO3-N content, and the optimal recycle ratio （ 2.5 ） is obtained by the test. The pollutions content of the influent must decrease to a certain level to make sure that the biological treatment runs effectively, the influent CODα, and NH3-N content should be 150 0 mg/L and 140 mg/L respectively. It is confirmed by the test that the two phase A/O process can treat the wastewater from pathalocyanine production after its pre-treatment.
