【摘要】 采用化工、冶金行业较常用的规整填料塔吹脱去除垃圾渗滤液中的氨氮 ,对于氨氮浓度高达 150 0～ 2 50 0mg/L的渗滤液取得较好的处理效果。在温度为 2 5℃ ,pH值为 10 5～ 11 0 ,气液比为 2 90 0～ 360 0时氨吹脱效率达 95%以上更多还原

【Abstract】 Air stripping tower with normal package was adopted to treat leachate of urban refuse landfill yard for ammonia nitrogen removal. Fair result had been gained for leachate with high ammonia nitrogen concentration in sphere of 1 500～2 500 mg/L. In condition when temperature was 25 degree Celsius and Air/Liquid ratio was in range of 2 900 ～3 600, over 95% of ammonia nitrogen was removed by stripping.更多还原
