【摘要】 对吹脱法去除垃圾渗滤液中的氨氮进行了研究 ,控制吹脱效率高低的关键因素是温度、气液比和 pH值。在水温大于 2 5℃ ,气液比控制在 35 0 0左右 ,渗滤液 pH值控制在 1 0 5左右 ,对于氨氮浓度高达 2 0 0 0～ 4 0 0 0mg/L的垃圾渗滤液 ,去除率可达到 90 %以上更多还原

【Abstract】 Air stripping was adopted to treat leachate of refuse landfill yard for ammonia nitrogen removal in our study. The key factors in ammonia nitrogen removal were temperature, air liquid ratio and pH. In condition when temperature was 25 ℃, air liquid ratio was in range of about 3500, and pH was controlled in 10.5, over 90% of ammonia nitrogen was removed by air stripping.更多还原
