利用反渗透技术处理垃圾渗滤液会产生大量的浓缩液。试验利用回灌法处理浓缩液，设计了3个垃圾柱体，对不同好氧、厌氧条件下，反渗透浓缩液进行回灌处理。检测垃圾柱体的出水COD，氨氮，ORP，电导率情况，来判断回灌法处理反渗透浓缩液的处理效果。试验结果表明：①厌氧回灌浓缩液的效果较好，适于实际应用；②氨氮去除率在50%左右，限制氨氮去除率的主要因素是碳氮比低；③盐的去除率在35%左右。
利用反滲透技術處理垃圾滲濾液會產生大量的濃縮液。試驗利用迴灌法處理濃縮液，設計瞭3箇垃圾柱體，對不同好氧、厭氧條件下，反滲透濃縮液進行迴灌處理。檢測垃圾柱體的齣水COD，氨氮，ORP，電導率情況，來判斷迴灌法處理反滲透濃縮液的處理效果。試驗結果錶明：①厭氧迴灌濃縮液的效果較好，適于實際應用；②氨氮去除率在50%左右，限製氨氮去除率的主要因素是碳氮比低；③鹽的去除率在35%左右。

Using reverse osmosis technology to deal with waste landfill leachate will produce a lot of concentrate liquor. In this experiment, recirculation was used to treat concentrated liquor. The value of COD, ammonia nitrogen, ORP and conductivity in the effluent was detected as the judging of the reverse osmosis concentrate treatment effect. Three cylinders were designed for different aerobic conditions to recycle the waste landfill leachate. The experimental results showed that:(1) Anaerobic recirculation technology was better and could be applied to project. (2)Ammonia nitrogen removal efficiency was about 50%and the main restrict factor was low carbon nitrogen ratio.(3)Salt removal rate was about 35%.
