摘要
天津市地下水不同程度地受到NH4+污染。对天津市有代表性的7类含水介质土样进行了NH4+的吸附 研究,确定了土样的阳离子交换容量,研究发现实验土样对NH4+的吸附模式均符合langmuir等温吸附模式。利 用土柱实验结果识别了NH4+在实验土样中的迁移滞后系数并建立了NH4的一维迁移模型。
The groundwater is polluted to varying degree by NH4+ in Tianjin City. The absorption of seven kinds of soil was studied. The cation exchange capacity of soils was determined. The absorption model of soils accords with Langmuir absorption model. The transport lag coefficient of NH4+ in soils was determined by the soil column experiment and the one-dimension transport model was established.
