摘要
胶体在地下环境中的迁移沉积行为是其重要环境过程之一.胶体穿过土壤层进入地下水环境后,其携带污染物会随地下水流而迅速扩散迁移.由于地下环境相对复杂,地下水污染通常较难治理和控制,其会直接或间接地影响生态环境以及人类健康.因此,研究胶体在多孔介质中的迁移和沉积机制,对维护地下水安全有重要的实际意义.从五个方面综述了胶体在多孔介质中迁移沉积的影响因素,包括多孔介质特性、土壤类型结构和化学因素,并对未来研究的发展进行了展望.
Abstract
The transport and deposition behavior of colloids in underground environment is one of the important environmental processes.Through the soil layer into the groundwater environment,colloid will flow down the water and quickly diffuse carrying pollutants.Limited to the complex underground environment,groundwater pollution is usually difficult to control,which directly or indirectly affects the ecological environment and human health.Therefore,it is of great practical significance to study the transport and deposition mechanism of colloid in porous media to maintain the safety of groundwater.In this paper,the factors affecting the transport and deposition of colloid in porous media were reviewed from five aspects,including the characteristics of porous media,soil type and structure,surface coating properties,chemical factors and biological influencing mechanisms,and the future research development was prospected.
