In this work the complete treatment of soil spiked with lindane is studied using surfactant-aided soil-washing (SASW) to exhaust lindane from soil and electrolysis with diamond anodes to mineralize lindane from the soil washing fluid (SWF) waste. Results demonstrated that this technological approach is efficient and allow to remove this hazardous pollutant from soil. They also pointed out the significance of the ratio surfactant/soil in the efficiency of the SASW process and in the performance of the later electrolysis used to mineralize the pollutant. Larger values of this parameter lead to effluents that undergo a very efficient treatment which allows the depletion of lindane for applied charges lower than 15AhL and the recovery of more than 70% of the surfactant for the regeneration of the SWF.
本工作研究了用表面活性剂辅助土壤洗涤（SASW）处理土壤中林丹的全过程，以从土壤中去除林丹，并用金刚石阳极电解法将林丹从土壤洗涤液（SWF）废物中矿化。结果表明，该技术方法是有效的，可以从土壤中去除这种危险污染物。他们还指出了表面活性剂/土壤的比例在 SASW 过程的效率和用于矿化污染物的后续电解中的重要性。该参数的较大值会导致流出物进行非常有效的处理，这使得林丹的去除率可以低于 15AhL，并且可以回收超过 70％的表面活性剂，以再生 SWF。
