摘要
表面活性剂淋洗法已广泛应用于修复有机污染土壤,但存在表面活性剂使用量大和土壤淋洗液易造成二次污染等缺陷,因而需对淋洗液进行无害化处理和资源化再生。文章基于活化过硫酸盐产生的硫酸根自由基具有选择性氧化有机污染物的特性,综述淋洗液再生并回用于修复有机复合污染土壤的研究进展。
Surfactant flushing method has been widely used in remediation of organic contaminated soil.However,it has some defects,such as large amount of surfactant used and soil flushing solution is easy to cause secondary pollution.Therefore,it is necessary to carry out harmless treatment and recycling of flushing solution.Based on the properties of selective oxidation of organic pollutants by sulfate radical produced by activated persulfate,this paper reviewed the research progress of regeneration and reuse of eluent for remediation of organic compound contaminated soil.
