二氧化钛光催化降解处理氨氮废水

Study on Ammonia Nitrogen in Wastewater Degradation by TiO2 Photocatalysis

  • 摘要: 介绍了用TiO2和活性组分A复合在砖块颗粒上的(TiO2+A)催化剂的制备,用(TiO2+A)催化剂对氨氮废水进行了降解实验研究,并且对降解过程中的反应动力学进行了探讨.结果表明:(TiO2+A)催化剂对模拟氨氮废水的处理效果好,当反应时间为24 h时,氨氮的去除率可达95%以上;光催化氧化反应为一级反应;以砖块颗粒为载体(TiO2+A)催化剂的光催化活性高,不流失,制作简单.对某化肥厂氨氮废水降解实验表明,8 h内可使ρ(氨氮)从238 mg/L降至8 mg/L,降解率达97%.
