摘要:

在西北黄土地区某填埋场进行钻孔取样和渗滤液水位测试,在室内对不同深度土样的Cl-和COD质量浓度进行测试分析,获得该填埋场运行19 a后渗滤液在底部压实及天然黄土层迁移情况.针对该填埋场,建立污染物迁移的二维有限元数值模型,通过实测数据的反演分析率定出Cl-和COD在场底土层中的迁移参数,并对该填埋场继续运行至50 a时污染物的迁移进行预测.测试结果表明:该填埋场运行19 a后COD和Cl-在压实及天然黄土层中最大竖向迁移深度分别为3 m和7 m,水平向迁移距离有限,黄土对COD具有较强的吸附阻滞作用.模拟预测结果表明:在18.5 m高渗滤液水头作用下,填埋场运行50 a时渗滤液中COD和Cl-的最大迁移深度分别达5 m和15 m.

Abstract:

Borehole sampling and measurement of leachate levels were carried out at a landfill of municipal solid wastes in the Northwest region of China. The soil samples at different depths were collected to determine the mass concentrations of Cl ion and COD in laboratory. The situation of leachate transport in the compacted and natural loess soil strata under the landfill after 19 years’ operation was obtained. 2D finite element models were set up to simulate the transport of leachate under the landfill. The model parameters of Cl ion and COD were obtained by back analysis of the measured Cl ion and COD mass concentration profiles. Longterm simulation of 50 years was carried out to predict the migration of Cl ion and COD into the soil strata. The test results show that after 19 years’ operation, the vertical migration depth of COD in the compacted and natural loess was 3 m and that for Cl ion was deeper than 7 m, and the horizontal migration distances of Cl ion and COD were limited. Results indicate that the loess has a significant adsorption retardation effect on COD. The simulation results show that, with a leachate head of 18.5 m, the migration depth of Cl ion and COD after 50 years’ operation is 15 m and 5 m, respectively.
