| 中文摘要:在综合国内外文献的基础上，通过现场实地调查和室内物理模拟试验、渗滤试验、污染物化学动力学转化试验，概化建立了上海老港垃圾堆放场以有机氮、ＮＨ＋４、ＮＯ－２、ＮＯ－３４种离子为污染质的非饱和土层－潜水含水层水动力弥散联合数学模型，应用所建联合数学模型对上海老港大型垃圾堆放场的地质、水文地质条件、垃圾浸沥液发生量、污染质的运移和转化进行了模拟计算和预测分析。预测了垃圾堆放期１０年和封场后２０年内污染质在非饱和土层－潜水含水层中迁移、转化的规律和排污去向，并得出如果保持目前垃圾堆放状态，其污染范围每年将向内陆含水层扩展９０～１００ｍ的预测结果。这些预测分析为上海浦东新区垃圾堆放场的环境保护提供了科学依据。 |

| Abstract:On the basis of water and pollutants movement,transformation simulation test under the condition of different soil columns,a dynamic model for the soil_groundwater system was described.The model includes 9 main models of water and 4 pollutents(organic N, NH + 4、NO - 2、NO - 3)transport and transformation in the unsaturated and saturated zone.The integrated simulation model was used to simulate wastewater and pollutants movement under the condition of landfill in Laogang town,Shanghai City,and got a lot of modeling results of influencing distances and intensity by Landfill during the 10 years of garbage heaping stage and 20 years after stopping garbage heaping.Also,it provide a simulated result that the distances of groundwater intrusion by landfill waste water is 90～100 m each year. |
