摘　　要：【目的】探究载镍活性氧化铝/臭氧催化氧化协同吸附技术去除焦化废水中COD的最佳工艺路线。【方法】采用浸渍法,将镍负载于活性氧化铝上,测定该活性氧化铝催化臭氧氧化的吸附性能。【结果】当硝酸镍浓度为0.8mol/L、臭氧量为5g/h时,载镍活性氧化铝催化臭氧氧化焦化废水COD的去除效率最大,约为51.13%。【结论】相较于单独使用吸附和臭氧催化氧化技术,载镍活性氧化铝催化臭氧氧化协同技术大大提高了废水中COD的去除效果,为焦化废水中COD去除提供支持。[Purposes]This paper aims to investigate the optimal process for removal of COD from coking wastewater by the synergistic adsorption of nickel-loaded activated alumina ozonation and catalytic oxidation.[Methods]Nickel was loaded onto the activated alumina by impregnation method to determine the adsorption properties of the activated alumina for catalytic ozonation.[Findings]When the concentration of nickel nitrate was 0.8 mol/L and the amount of ozone was 5 g/h,the COD removal efficiency of coking wastewater by nickel-loaded activated alumina catalytic ozonation was the highest(about 51.13%)[Conclusions]Compared with adsorption and ozone catalytic oxidation alone,the combined technology of nickel activated alumina catalytic ozonation greatly improves the removal efficiency of COD in wastewater,and provides support for the removal of COD in coking wastewater.
