摘　　要：研究了在低温和常压条件下,精馏与催化氧化耦合工艺处理炼油厂废水。以γ-Al_2O_3为载体,Cu、Fe、Mn、Zn、Cd和Ni为主要活性组分,采用浸渍法制备了负载型催化剂,并对其进行XRD表征。利用反应精馏原理,以金属氧化物为催化剂,氧化降解炼油污水,探讨了催化剂的催化寿命与稳定性。结果表明,CuO/γ-Al_2O_3·H_2O_2催化处理炼油废水的COD去除率可达96.2%,催化剂连续使用效果较好。The refinery wastewater was purified under coupling process of distillation and catalytic oxidation. low temperatures and atmospheric pressure by the The supported catalysts were prepared by impregnation method using γ-Al2O3 as the carrier and Cu, Fe, Mn, Zn, Cd and Ni as main active components, and characterized by XRD. Using catalytic oxidation-distillation process, the refinery wastewater was treated by supported catalysts and the life and stability of the catalyst were investigated. The results showed that the CuO/γ-Al2O3 catalyst exhibited better catalytic effect and could be used continuously. COD removal rate for treating refinery wastewater reached 96.2%.
