The preparation of tamarind fruit seed granular activated carbon (TSAC) by microwave induced chemical activation for the adsorptive treatment of semi-aerobic landfill leachate has been attempted. The chemical and physical properties of TSAC were examined. A series of column tests were performed to determine the breakthrough characteristics, by varying the operational parameters, hydraulic loading rate (5-20 mL/min) and adsorbent bed height (15-21 cm). Ammonical nitrogen and chemical oxygen demand (COD), which provide a prerequisite insight into the prediction of leachate quality was quantified. Results illustrated an encouraging performance for the adsorptive removal of ammonical nitrogen and COD, with the highest bed capacity of 84.69 and 55.09 mg/g respectively, at the hydraulic loading rate of 5 mL/min and adsorbent bed height of 21 cm. The dynamic adsorption behavior was satisfactory described by the Thomas and Yoon-Nelson models. The findings demonstrated the applicability of TSAC for the adsorptive treatment of landfill leachate.
尝试使用微波诱导化学活化法制备罗望子果核颗粒活性炭（TSAC），用于半好氧垃圾填埋场渗滤液的吸附处理。研究了 TSAC 的化学和物理性质。通过改变操作参数（水力负荷率为 5-20mL/min 和吸附床高度为 15-21cm）进行了一系列柱试验，以确定穿透特性。定量分析了氨氮和化学需氧量（COD），这为预测渗滤液质量提供了必要的见解。结果表明，TSAC 对氨氮和 COD 的吸附去除具有令人鼓舞的性能，在水力负荷率为 5mL/min 和吸附床高度为 21cm 时，氨氮和 COD 的最高床容量分别为 84.69 和 55.09mg/g。Thomas 和 Yoon-Nelson 模型对动态吸附行为进行了较好的描述。研究结果表明，TSAC 可用于吸附处理垃圾渗滤液。
