| 中文摘要 | Al2O3催化剂对邻苯二甲酸二甲酯(DMP)溶液臭氧化过程的影响结果表明:Al2O3可以显著提高臭氧氧化的效果,反应120min后,TOC的去除率从单独臭氧氧化的23.9%提高到55.1%.实验中还考察了制备条件对Al2O3催化剂活性的影响并确定了反应的最佳工艺条件.在实验考察的范围内:焙烧温度600℃,Al2O3粒径为0.5~1.0mm时催化活性最高;最佳反应工艺条件为:催化剂投加量20g/L,混和气体流速200mL/min,反应温度15℃.通过单独臭氧氧化,单独臭氧氧化后再进行催化剂吸附,催化臭氧化的对比实验证明了Al2O3催化剂对体系TOC的去除主要是基于催化作用.; With dimethyl phthalate as the model pollutant and alumina as catalyst,the degradation of TOC system was systemically investigated.Results show that Al_2O_3 can significantly increase the effect of ozonation,and TOC removal rate in 120 minutes can reach 55.1% while only 23.9% with alone ozone.Al_2O_3 activeness is upmost under the follow conditions: calcination temperature,600℃;particle diameter,0.5～1mm;catalyst dosage,20g/L;gas flow rate,200mL/min,react temperature,15℃.The contrastive experiments of alone ozone,catalyst adsorption after ozonation and catalytic ozonation confirmed that catalytic reaction is the most important process to TOC removal in system with alumina as catalyst.; 国家自然科学基金项目(50238020) |
