| 摘 要： | 采用土柱试验模拟水污染与水修复的环境,系统地研究了不同介质对原位曝气技术去除地下水中柴油污染的影响。结果表明:大量水相中的柴油在曝气的开始阶段被去除,越接近空气输入位置污染物去除效果越好,同时粗沙介质中污染物去除的最终效果最好;介质的渗透系数与去除效率有直接关系,渗透系数越大,污染物的去除效率越高,渗透系数越小,污染物的去除效果越差,越易产生拖尾现象。

| Abstract: | Through soil column test,this paper simulated the environment of water pollution and water restoration,and column test were is used to study different media's effect on Air Sparing(AS) techniques for removing underground diesel pollution.It is shown that a lot of diesel fuel in aqueous phase is removed at the beginning.The closer to the air inlet,the better effect on contaminants removals is,meanwhile the final effect on removing contaminants in the medium of coarse sand is the best.The removal efficiency i... |
