不同龄期渗滤液污染物吸附降解实验及数值模拟

为深入了解垃圾渗滤液在土壤水环境中的运移,揭示不同龄期渗滤液中有机污染物迁移转化规律,以阜新垃圾填埋场为研究对象,通过室内模拟吸附、降解及迁移实验,研究了渗滤液有机污染物在土壤水环境中迁移和作用机理;拟合实验结果求出模型参数,并通过建立的数学模型对污染物在土层中穿透过程进行了模拟预测,结果表明新鲜样穿透能力较强。为预测垃圾渗滤液污染物对环境的潜在危害和安全处置提供理论依据。

Adsorption and Degradation Experiment and Numerical Simulation of Leachate Contaminant in Different Periods

To learn more about the behavior of landfill leachate in soil and water,and disclose the transport and transmute law of organic contaminant of landfill leachate in different period,the article studied the transport and action mechanism of leachate organic contaminant in soil and water by indoor simulative adsorption,degradation and transport experiments,taking Fuxin Landfill Plant as the object.The model parameters were obtained by fitting the experiment result.And the established mathematical model was used to simulate and predict the breakthrough process of contaminant in soil layers.The result showed that the fresh sample had a better breakthrough ability.The experiment provides theoretical basis for predicting the potential danger and safe disposal of leachate to environment.
