Soil washing is a well-known technology for the remediation of soils polluted by organic contaminants, including polycyclic aromatic hydrocarbons (PAHs). This study aimed to go further by integrating soil washing and permeable reactive barriers (PRBs) made of cork granules to remove PAHs from the soil. While PAHs may be transferred from the soil to the washing solution in the soil washing step, the cork PRB may provide the removal of PAHs from the washing solution, ultimately leading to the reuse of this solution.

土壤冲洗与软木渗透反应屏障相结合的多环芳烃污染土壤修复

土壤洗涤是一种众所周知的修复被有机污染物污染的土壤的技术，包括多环芳烃（PAHs）。本研究旨在通过整合土壤洗涤和由软木颗粒制成的渗透性反应屏障 (PRB) 来进一步去除土壤中的 PAHs。虽然 PAHs 可能在土壤洗涤步骤中从土壤转移到洗涤溶液中，但软木 PRB 可以从洗涤溶液中去除 PAHs，最终导致该溶液的重复使用。
