对单独臭氧氧化处理制浆废水与γ-Al₂O₃催化臭氧深度处理制浆废水进行了对比研究，结果表明: γ-Al₂O₃对臭氧具有一定的催化作用，能够显著提高废水的COD_Cr去除率; 随着主要影响因素pH 值、反应温度、臭氧浓度和催化剂用量的增加，COD_Cr去除率均先增大后降低; 同时，γ-Al₂O₃催化臭氧还能够有效地降低废水中AOX( 可吸附有机卤化物) 的含量; 实验室条件下，处理30min，AOX 去除率可达80． 4%． 文中还采用扫描电镜对再生前后的γ-Al₂O₃、采用UV 和GC-MS 对处理前后的废水进行分析，结果显示，γ-Al₂O₃催化臭氧能大幅降低废水中的有机物种类和含量，并且能较好地降解难生物降解的有机物，其作为催化剂具有良好的稳定性，重复使用8 次后，经过焙烧再生，仍可保持88． 5%的催化活性．

In this paper,a comparison was carried out between the ozone oxidation and the γ-Al₂O₃ -catalyzed ozonation for the treatment of bagasse pulping effluent.The results show that ( 1) γ-Al₂O₃ has a certain catalytic effect on ozone and can significantly improve the removal rate of COD_Cr ; ( 2) with the increase of pH value,reaction temperature,ozone concentration and catalyst dosage,the removal rate of COD_Cr first increases and then decreases; ( 3) the catalytic ozonation by γ-Al₂O₃ can also effectively remove the content of AOX ( Absorbable Organic Halogen) in the pulping effluent; and ( 4) in laboratory conditions,the removal rate of AOX reaches 80. 4% after a treatment for 30 min.Moreover,it is demonstrated by the UV and GC-MS results before and after the advanced treatment that γ-Al₂O₃ -catalyzed ozonation can significantly reduce the type and content of organic matters in the effluent and effectively degrade hard biodegradable organic matters; and that γ-Al₂O₃ is of good stability and repetition,concretely,after being reused for eight times,it still keeps 88. 5% of the catalytic activity.
