| 摘 要： | 填海工程使滨海地区的地下水物理化学条件改变,导致该区域地下水中重金属浓度升高。本文以深港西部通道填海区为例,采用实验室模拟填海条件的办法,初步探讨了影响填海区地下水重金属迁移的关键因素。模拟实验结果表明,填海区地下水中钨元素含量升高与地下水淡化、淤泥氧化过程以及填料风化有关;铜元素含量升高则与淤泥氧化过程以及填料风化有关;钒元素含量升高与地下水淡化和淤泥氧化过程有关,而其他元素含量升高则主要与填料风化释放有关。

| Abstract: | Reclamation activities reduced some physico-chemical characters such as pH,Eh and salinity of ground water changed.Those changes in the burial conditions of mud and the properties of the pore water in the mud may induce the release of some heavy metals in the mud to the groundwater at the reclamation site.Laboratory analyses and batch experiments were carried out to investigate what was the key to induce the release of heavy metal in the mud at reclamation site.The results of the simulation experiments suggested that the reclamation activities lead to a release of some heavy metals from sea mud and fill material.The process of air dry and groundwater refreshing aroused a release of Cu,V to the water.The fill material weathering and leaching can increasing concentration of Mn and Cu in the groundwater.Mixture of mud and fill material hardly released those heavy metal to the water,it suggested it would not lead to heavy metal release when the sea mud contacted directly with fill material. |
