The performance of a carbon-mineral composite adsorbent used in a fixed bed column for the removal of ammoniacal nitrogen and aggregate organic pollutant (COD), which are commonly found in landfill leachate, was evaluated. The breakthrough capacities for ammoniacal nitrogen and COD adsorption were 4.46 and 3.23 mg/g, respectively. Additionally, the optimum empty bed contact time (EBCT) was 75 min. The column efficiency for ammoniacal nitrogen and COD adsorption using fresh adsorbent was 86.4% and 92.6%, respectively, and these values increased to 90.0% and 93.7%, respectively, after the regeneration process.
评价了一种固定床柱状碳-矿物复合材料吸附剂对垃圾渗滤液中常见的氨氮和聚合有机污染物（COD）的去除性能。该吸附剂对氨氮和 COD 的吸附穿透容量分别为 4.46 和 3.23mg/g，最佳空床接触时间（EBCT）为 75min。使用新鲜吸附剂时，对氨氮和 COD 的柱效率分别为 86.4%和 92.6%，经过再生过程后，分别提高到 90.0%和 93.7%。
