深港西部通道填海区地下水Zn、Co、Pb、Mn迁移影响因素的研究

填海工程会扰动滨海地区的环境平衡,导致区域地下水中多种重金属浓度的变化.为探明重金属浓度发生变化的确切原因,为最大限度减少填海工程对环境影响提供参考依据,本文以深港西部通道填海区为例,通过实验室模拟填海条件,研究了填海区重金属迁移的关键影响因素.结果表明,填海区地下水中Zn含量升高与地下水淡化、淤泥氧化过程及填料风化有关;Co、Mn含量升高则主要与填料风化释放有关;Pb则保持较稳定的状态.

Mobility Research of Zn,Co,Pb and Mn in Reclamation Sites in the Shenzhen-HongKong Western Corridor

Reclamation activities induce changes of many physico-chemical characteristics such as pH,Eh and salinity of ground water.The changes of the burial conditions of mud and the properties of the pore water in the mud may cause heavy metals releasing from mud to groundwater at reclamation sites.In order to find out the exact reasons of metal concentration changing,and to provide a reference basis for minimizing the environment impacts of reclamation engineering,Laboratory analyses and batch experiments were car...
