Abstract:

利用由微孔疏水性聚丙烯中空纤维制成的工业级膜组件对垃圾渗滤液中氨氮进行支撑气膜法脱除研究,考察了泡沫分离-石灰絮凝等预处理技术对垃圾渗滤液表面张力及COD值的处理效果,在此基础上研究了物料因素和操作因素对膜传质性能的影响,并对该工艺的长期操作稳定性进行了研究。实验结果表明该预处理技术不仅可显著提高垃圾渗滤液的表面张力,还可大大降低其色度和COD值。当进料流量为100L/h、进料氨氮浓度为1000~3000mg/L、硫酸吸收液流量为200L/h、硫酸浓度为6%~10%、温度为20~30℃时,支撑气膜过程(两级膜组件串联)可有效脱除垃圾渗滤液中99%以上的氨氮,同时得到含10%~15%硫酸铵的水溶液作为副产品。工业级支撑气膜组件在连续运行的2个月内保持了良好的传质稳定性。
