摘要
为了提高臭氧催化氧化技术对工业废水中有机污染物的去除效率,采用浸渍法,将铁负载于活性氧化铝上.当硝酸铁浓度为0.8 mol/L、臭氧量为5g/h时,载铁活性氧化铝催化臭氧氧化工业废水有机污染物的去除率最大,约为56%.相比单独使用吸附和臭氧催化氧化技术,它大大提高了废水有机污染物的去除效果.因此载铁活性氧化铝催化臭氧氧化可作为高浓度工业废水去除有机污染物的一种有效方法.
Abstract
In order to improve the removal efficiency of COD from industrial wastewater by ozonation catalytic oxidation technology,the impregnation method was used to load iron onto the activated alumina.When the concentration of ferric nitrate was 0.8 mol/L and the amount of ozone was 5g/h,the removal efficiency of COD from industrial wastewater was increased,the removal efficiency of COD from industrial wastewater by catalytic ozonation with iron-carrying activated alumina is the highest,with a maximum removal efficiency of about 56％.Compared with adsorption and ozone catalytic oxidation alone,it greatly improves the removal effect of organic pollutants in wastewater.So catalytic ozonation with iron-carrying activated alumina can be an effective method to remove COD from high concentration industrial wastewater.
