催化湿式氧化法处理高浓度染料废水的研究

Degradation of High Concentration Dye Wastewater by Catalytic Wet Air Oxidation

通过共沉淀法制备了Co-Zn复合氧化物催化剂,用于催化湿式氧化处理高浓度分散红玉染料废水。结果表明,在400℃焙烧制得的Co-Zn摩尔比为1∶1的催化剂氧化活性较高,当分散红玉染料废水的COD为10000mg/L、反应温度为150℃、反应压力1.0～1.2MPa时,反应60分钟,COD去除率达到80%。

Co-Zn complex oxide catalysts for catalytic wet air oxidation of high concentration dye wastewater containing Disperse Rubine S-2GFL were prepared by coprecipitation methods.The results showed that Co-Zn(1∶1)catalyst calcined at 400℃ exhibited better activity,the highest COD removal efficiency was achieved to 80% after 60 minutes reaction when the reaction conditions were 150℃,1.0-1.2MPa,COD of Qisperse Rubine dye wastewater 10000mg/L.
