【摘要】 污染土壤淋洗技术是修复污染土壤的一种新方法 ,是对污染土壤生物修复的一种补充 ,使污染土壤修复的系统化成为可能。淋洗法主要使用淋洗剂清洗土壤 ,使土壤中污染物随淋洗剂流出 ,然后对淋洗剂及土壤进行后续处理 ,从而达到修复污染土壤的目的。因为淋洗剂的种类和淋洗方式的不同 ,土壤淋洗法可分为许多种类。土壤淋洗法主要受土壤条件、污染物类型、淋洗剂的种类和运行方式等因素影响。综合考虑多方面因素 ,就有潜力设计出经济高效的土壤淋洗系统。土壤淋洗法有很多优点 ,尽管也存在一些问题 ,但其技术上的优势也是其他方法难以取代的 ,所以有良好的应用前景。更多还原

【Abstract】 Soil washing process is a newly developed method for the remediation of contaminated soil, and it is an important complement to the bioremediation of contaminated soil and makes remediation of contaminated soil more systematic. Washing liquid is majorly used in the soil washing process to have contaminated soil cleaned, the comtaminants are flushed out by washing liquid, and the spent washing liquid and washed soils must be further treated, then could the aims of contaminated soils remediation be achieved. Soil washing could be classified into many types as different kinds of washing liquids are employed and different styles are operated. Soil washing process is affected by factors such as soil conditions, contaminant characters, washing liquid types and operation styles. After a systematic consideration, it might be possible to come up with an economical, practical and efficient soil washing system. The advantages of soil washing are so obvious that even with some problems, developing trend of this technique can’t be substituted by other methods and bright future of this method can’t be neglected.更多还原
