阐述了异位土壤淋洗法的流程、优势和局限性,分析了影响修复效果和费用的因素.并按淋洗方法和淋洗剂对土壤淋洗法进行了分类,在此基础上对近年来土壤淋洗在重金属和有机污染物污染土壤修复的应用进行了回顾和评价,列举了典型的研究和应用实例.土壤淋洗法在我国的研究和应用还有较大不足,今后需要在淋洗技术、淋洗装置与设备、新型淋洗剂,特别是生物表面活性剂和天然螯合剂等方面加强研究,并通过与其他土壤修复技术的联用,提高土壤异位淋洗技术的实用性,使其得以进一步改进和推广.

In the paper,procedures,advantages and limitations of ex-situ soil washing are described and the major factors influencing the remediation effects and costs are also analyzed.According to the operation procedures and eluent types,ex-situ soil washing technology is classified.Then,the recent application progress of soil washing in remediation of soils contaminated by heavy metals and organic pollutants are reviewed and evaluated,with typical researches and application cases listed.At present,research and application of ex-situ soil washing are insufficient in China.Therefore,it is necessary to ...
