摘要

Soil contamination by organic compounds is one of the most concerned issues on polluted soil.It is well known that there are limited methods to remediate the contaminated soil on site.Especially,the in-situ method for contaminated soil is too difficult to de-contaminate the organic pollutant.In this study,the fundamental ability of soil remediation,which aimed to decrease oil concentration in,in-situ process,have been researched by using a high pressure gas generated from "crush composition" on artificially oil contaminated soil.The n-hexadecane (n-C16H34) and other organic compounds were selected as soil oil contaminators,gravimetric analysis by soxhlet extraction and GC-MS were used as qualitative and quantitative analysing methods.For the experimental examination,the influences on the difference in the concentration of n-hexadecane (and other organics),the tamping amount,position and repetition of crush composition in soil,and scale (size) of experimental model were investigated.The n-hexadecane concentration reduced by the explosive effect of crush composition showed a reasonable decrease of about 30 wt%～60 wt% compared to the initial n-hexadecane.The removed amount of n-hexadecane and distance from explosion point of the crush composition was related in scale and model of contaminated soil.
