【摘要】 以双氧水为氧化剂,以酸性大红3R模拟废水为处理对象,进行了湿式催化氧化技术催化剂的制备条件实验研究,实验表明:催化剂的最佳制备条件为:以硅胶为载体,以Cu为活性组分,浸泡液浓度为0.15mol/L,以水浴锅加热促进硅胶对Cu的负载,反应温度为70℃,反应时间为4h,浸泡后在鼓风干燥箱中100℃下烘干2h,然后再在箱式电阻炉中450℃下焙烧4h。制备所得的催化剂与双氧水进行催化氧化实验,经处理后,废水的脱色率达到了97.15%,COD去除率达到了81.16%。更多还原

【Abstract】 With hydrogen peroxide as oxidant,acid red 3R simulated wastewater as disposing objects,conduct a research on the preparation conditions of catalysts for wet catalytic oxidation technology.Experiments show that:the best preparation condition for catalyst is:using silica gel as the carrier,Cu as the active component,the concentration of impregnating solution is 0.15mol/L,heating with water-bath to facilitate loading of Cu on silica gel,the reaction temperature is 70℃ and reaction time is 4h.After soaking,dry it in the blast oven for 2h unde 100℃,then roast for 4h under 450℃ in the box-type resistance furnace.Carry on the catalytic oxidation experiment with the obtained catalysts and the hydrogen peroxide,after disposing,the decol-orization rate of wastewater achieved 97.15%and the COD removal rate 81.16%.更多还原
