摘要
华北某焦化场地土壤受到苯及多环芳烃污染,在分析土壤多种污染物组成的基础上,开展低温技术修复污染土壤实验,并研究不同温度及处理时间参数对污染土壤污染物修复的效果。结果表明:提高温度和处置时间对苯及多环芳烃的脱除效果越好,土壤污染物的脱附效果和其沸点的关联性较大,温度参数对污染物脱附的影响效果要显著高于时间参数。
The soils of coking site in Northern China were polluted by benzene and polycyclic aromatic hydrocarbons（ PAHs）,on the basis of analyzing the composition of various soil pollutants. The test of the low temperature technology was carried out to repair contaminated soil,and the effects of different temperature and treatment time parameters on the remediation of contaminated soil pollutants were studied. The results showed that： Improving the temperature and the disposal time had a good effect on the removal efficiency of benzene and polycyclic aromatic hydrocarbons,the desorption effect of soil pollutants was related to the boiling point,and the effect of temperature parameters on the desorption of pollutants was significantly higher than time parameter.
