中文摘要：

在不同的环境条件下，以南昌市填埋场垃圾渗滤液为研究对象，研究了矿化垃圾对渗滤液中COD和氨氮吸附效果与其粒径、用量、渗滤液pH和振荡时间的关系，并对吸附等温线模型进行拟合。实验表明：矿化垃圾对COD的去除率最高可达76．49％，最大吸附量为97．44mg／g，吸附COD的最佳条件为矿化垃圾粒径〈2mm、用量50g／L、pH值11、振荡时间510min；矿化垃圾对氨氮的去除率最高可达75.43％，最大吸附量为17．80mg倌，最佳条件为矿化垃圾粒径〈2mm、用量50g／L、pH值11、振荡时间600min。通过对等温吸附线的拟合得出：矿化垃圾对COD的吸附更符合Frcundlich方程，属于多层吸附；对氨氮的吸附则更符合Langmuir方程，属于单层吸附。

英文摘要：

Experiments under different environmental conditions on the adsorption of COD and ammonia-nitrogen in landfill leachate from a landfill of Nanchang, Jiangxi Province was conducted by using aged refuse as the absorbents. Effect of particle size, dosage, pH and reaction time on adsorption of COD and ammonia-nitrogen onto aged refuse were separately studied, and the adsorption isotherm models were fitted. Experiment results showed that the maximum adsorption capacity of COD was 97.44 mg/g under the optimum condition of particle size less than 2 millimeter, dosage of 50 g/L, pH of 11 and reaction time 510 min; the maximum adsorption capacity of ammonia-nitrogen was 17.80 mg/g under the optimum condition of particle size less than 2 millimeter, dosage of 50 g/L, pH of 11 and reaction time 600 min. Through fitting the sorption isotherms, the results showed that the sorption of COD was more accorded with Freundlich equation and belongs to the multilayer adsorption, while the sorption of ammonia-nitrogen was more accorded with Langmuir equation and belongs to the monolayer adsorption.
