| 摘 要： | 目的研究Cu／Ce复合金属氧化物对废水催化氧化程度的影响。方法采用湿式氧化法在2L反应釜中处理吡虫啉农药废水。结果Cu／Ce复合氧化物催化剂对吡虫啉农药废水具有较高的催化活性。结论优化催化剂的设计和制备方法，不但可以提高COD的去除率，而且可有效的降低Cu^2＋和Ce^4＋的溶出量，使该类催化剂具有广阔的使用前景。

| Abstract: | Aim To affect COD removal efficiency of wastewater by using copper and cerium oxide catalysts.MethodsThe catalytic wet air oxidation of imidacloprid pesticide wastewater were studied in the 2L autoclave.ResultsThe activity of copper and cerium oxide catalysts were better than that of copper nitrate or cerium nitrate.Conclusion Some measures of controlling the leaching of Cu~(2+) and Ce~(4+),changing the reaction condition and optimizing the design and make of catalysts were discussed.The catalysts would have wide application prospect if the leaching could be controlled. |
