摘要
对比了常见的各类型垂直防渗优缺点,结合某滨海地区危险废物填埋场地质特性,选择了采用土-膨润土墙。基于在垂直防渗帷幕内,扩散作用对于污染物运移有较大的影响,在考虑分子扩散作用和吸附阻滞作用的情况下,确定了土-膨润土墙的垂直防渗帷幕厚度。
Compared with the advantages and disadvantages of various common types of vertical seepage prevention,and combined with the geological characteristics of a hazardous waste landfill in a coastal area,it is recommended to use a soil-bentonite wall.Based on the vertical seepage curtain,the diffusion effect has a great influence on the contaminant transport,and the vertical anti-seepage curtain thickness of the soil-bentonite wall is determined in consideration of molecular diffusion and adsorption retardation.
