摘    要:选用西北地区砂土为供试土壤,苯酚作为实验模拟研究的有机污染物,在电动修复技术的基础上加入超声波,联合降解土壤中的苯酚污染物。结果表明,电动技术修复苯酚污染土壤时,加入超声波有利于苯酚的迁移和富集。含水率的增加可以使苯酚的迁移距离增大,当土壤含水率为16%时,富集量可达到153%。超声波的声强可以使苯酚的迁移幅度增大,最大富集率可达到105%。因此,电动法联合超声波降解苯酚效果显著,具有良好的应用前景。

关 键 词:土壤污染  电动修复  苯酚  超声波

Abstract:Taking sand sedimented in Northwest China as the test soil and phenol as the organic pollutant,the electrokinetic remediation technology study on phenol degradation in soil matrix based on adding ultrasound energy was carried out in laboratory. The experimental results showed that the ultrasound could enhance the migration and accumulation of phenol when electrokinetically remediate phenol - contaminated soil. The increase of moisture contents could increase the movement distance of phenol. The accumulation...
