摘要
采用共沉淀法制取Cu-Mn-Fe复合金属氧化物,考察其催化湿式氧化苯酚废水的活性,并确定最佳工艺条件。结果表明,在催化剂用量为0.7g·L-1,30%过氧化氢用量为50m L·L-1,反应时间2h,反应温度55℃的条件下,苯酚废水的COD去除率最高可达71.9%。
The Cu-Mn-Fe composite oxide catalysts were synthesized by co-precipitation method. The activity of the catalysts in wet catalytic oxidation of phenol wastewater were investigated and the optimum conditions were determined. The results showed that the optimum preparation conditions were as followed： the amount of catalyst addition was 0.7g/L, the amount of 30% H2O2 addition was 50 m L/L, the treatment temperature was 55℃ and the treatment time was 2h. The highest removal rate of COD of phenol wastewater was 71.9%.
