摘要
为利用植物油去除污染土壤中的多环芳烃,研究了应用活性炭F400吸附柱再生含多环芳烃植物油的可行性,对含高浓度多环芳烃的植物油进行二级再生处理,优化了过程参数,比较了原植物油和经活性炭再生的植物油去除土壤中多环芳烃能力的差别。结果表明,活性炭吸附法可以实现含多环芳烃植物油的再生,证明了修复策略的可行性。二级处理可以进一步吸附植物油中的多环芳烃,且高分子量多环芳烃几乎完全被去除。再生植物油和原植物油去除土壤中多环芳烃的能力没有明显差别。
The feasibility of activated carbon adsorption treatment for regeneration of plant oil employed for removing polycyclie aromatic hydrocarbons （PAHs） from contaminated soil was demonstrated. The effective regeneration of the spent plant oil validates such application as a viable remediation option. The two-stage adsorption treatment in two serial adsorbers （F400 activated carbon, EBCT=60 rain each） removed virtually all of the high molecular weigh and most of the lower molecular weigh PAHs present in the spent plant oil. The regenerated oil performed nearly the same as the new plant oil in removing PAHs from the contaminated soil sample. Further optimization of the operating parameters will result in a more efficient process for regeneration of the plant oil spent on remediation of PAHs contaminated soil.
