中文摘要：
采用介质阻挡放电技术对菲污染土壤进行修复处理,研究了电源参数（电压、频率、占空比、放电间隙）对输入能量的影响,考察了电源参数、土壤参数、气体参数对处理效果的影响,并综合考虑处理效果、放电特性及能源利用等因素选取最佳参数以进行后续处理及机理研究。结果表明：在电源输入电压为110 V、脉冲频率为150 Hz、占空比为20%、放电间隙为1.5 cm、气体流速为0.6 L·min-1、初始浓度为200 mg·kg-1、土壤含水率为4%的条件下处理20 min后,DBD等离子体对菲污染土壤的降解率可达到82%,其输入功率为64 W,能源效率为0.04 mg·k J-1。
英文摘要：
Phenanthrene （PHE） contaminated soils were remediated by dielectric-barrier discharge （DBD） plasma. The effect of the power parameters （voltage, frequency, duty cycle, and discharging gap） on the input energy, as well as the influence of power, soil properties, and gas on the removal efficiency, was in- vestigated. The optimal condition was selected for the post-treatment and mechanism study by considering the treatment effect, discharging properties, and energy utilization. The results showed that the removal efficiency of PHE contaminated soil by DBD plasma technology could reach 82% after treatment for 20 min in the following conditions. These conditions were input voltage 110 V, pulsed frequency 150 Hz, duty cycle 20% , discharging gap 1.5 cm, airflow rate 0.6 L · min-1 , initial concentration 200 mg · kg-1 , and water content of the soil 4%. The input power in this instance was 64 W and the energy efficiency was 0.04 mg · kj-1.
