制备了不同组成的活性炭复合载体及催化剂,并将其用于臭氧催化氧化降解酸性大红染料废水化学需氧量(COD)的反应.比较了不同载体及催化剂的物性特征、COD去除率之间的差异,详细考察了pH、反应空速和臭氧投加量等参数对COD去除率的影响.结果显示,自制活性炭复合载体及催化剂具有强度高、磨耗低、介孔比例高且金属分散均匀等优点,较商用活性炭催化剂COD去除率高10.9％～ 16.5％.在空速为1.0h-1、pH为8、臭氧质量浓度为200 mg/L的条件下,Cu-Ce/AC-NTB催化剂COD去除率平均值达72.2％,稳定运行30 d没有明显降低,表现出良好的催化活性和稳定性.“,”Activated carbon composite supports and catalysts with different composition are prepared,and then used in degrading acid brilliant scarlet dye wastewater in terms of chemical oxygen demand (COD) by ozone catalytic oxidation.The physical properties of different supports and catalysts and the corresponding removal rates against COD are compared.The effects of pH value,reaction space velocity and ozone dosage on the removal rate of COD are investigated in detail.Results show that the self-made activated carbon composite supports and catalysts have the advantages of high strength,low attrition loss,high ratio of mesoporous and uniform metal dispersivity.The removal rates of COD over it are 10.9％-16.5％ higher than that over commercial activated carbon catalyst.Appropriate pH value,low space velocity and high ozone dosage are all helpful to improve the COD removal rate.When the space velocity is 1 h-1,pH value is 8 and ozone dosage is 200 mg·L-1,Cu-Ce/AC-NTB catalyst can bring about an average COD removal rate of 72.2％,and it can operate stably for 30 days,representing good catalytic activity and stability.
