摘要：本研究采用臭氧氧化工艺处理某企业污水处理站尾水，每隔0.5 h监测废水色度与苯胺类浓度的变化。试验结果表明，当氧化时间达到3 h时，废水中的苯胺类浓度低于方法检出限，从而实现苯胺类的零排放；调节废水pH，投加Ni-Cu催化剂，可以提高废水处理效率。

Abstract： In this study， the ozone oxidation process is used to treat the tailwater of a wastewater treatment station of an enterprise， and the change of the chroma and aniline concentration of the wastewater is monitored every 0.5 h. The test results show that when the oxidation time reaches 3 h， the concentration of aniline in the wastewater is lower than the detection limit of the method， thus realizing zero emission of aniline; the wastewater treatment efficiency can be improved by adjusting the pH of wastewater and adding Ni-Cu catalyst.
