【摘要】 研究了非均相催化氧化处理焦化废水的效果。实验得出处理焦化废水的最佳条件:采用经质量浓度为80 g/L的硝酸铜溶液浸渍后的γ-A l2O3为催化剂,废水pH为3,催化剂体积分数为40%,H2O2体积分数为4%,反应时间3 h以上。原水经处理后COD由4 540 mg/L降至600 mg/L以下,氨氮质量浓度由552 mg/L降至160 mg/L以下。更多还原

【Abstract】 The effects of treating coking wastewater by heterogeneous catalytic oxidation process were studied.The optimum conditions are as follows:γ-Al₂O₃ impregnated by 80g/L Cu（NO₃）₂ as catalyst,wastewater pH 3,volume fraction of catalyst 40% and that of H₂O₂ 4%,and reaction time above 3h.After treated,COD and mass concentration of ammonia nitrogen in the wastewater are reduced from 4 540mg/L to below 600mg/L and from 552mg/L to below 160mg/L,respectively.更多还原
