全球土壤资源污染严重,表面活性剂泡沫强化修复技术因泡沫流动受重力影响小、避免淋洗液难控制使区域扩大引发二次污染、修复效果好等备受关注。本文综述了表面活性剂泡沫强化修复技术在治理污染土壤中的研究进展,详细阐述了表面活性剂泡沫强化修复污染物的效果、机理、影响因素及应用前景,并就表面活性剂泡沫强化修复技术今后的研究方向进行了展望。
The global soil resources are seriously polluted. The surfactant foam strengthening and repairing technology has drawn much attention due to the small influence of gravity on the foam flow, the avoidance of difficult control of the eluent, the secondary pollution caused by the expansion of the area, and the good repairing effect. In this paper, the progress of surfactant-based foam remediation technology in the treatment of contaminated soils was reviewed. The effects, mechanism, influence factors and application prospects of surfactant-based foam remediation of contaminants were described in detail. In addition, the effects of surfactants on foam remediation The future research direction has been prospected.
