复合污染土壤修复方法
摘要：
本发明提供了一种复合污染土壤修复方法，包括如下步骤：(1)将十二烷基硫酸钠溶液注入或漫灌有机-重金属复合污染土壤，然后再将乙二胺二琥珀酸溶液注入或漫灌有机-重金属复合污染土壤；或者，先将乙二胺二琥珀酸溶液注入或漫灌有机-重金属复合污染土壤，再将十二烷基硫酸钠溶液注入或漫灌有机-重金属复合污染土壤；(2)再用水注入或漫灌受污染土壤。(3)收集步骤(1)和(2)排出的溶液，使用废铁屑即时处理，即可实现对有机-重金属复合污染土壤的绿色修复。本发明可对土壤进行原位修复，也可进行异位修复。本工艺方法具有操作简单，成本低，无二次污染等优点。
摘要（英）：

The invention provides a polluted composite soil repairing method comprising the following steps of: (1) injecting or flooding a lauryl sodium sulfate solution into organic-heavy metal polluted composite soil, and then injecting or flooding an ethylenediamine disuccinic acid solution into the organic-heavy metal polluted composite soil; or firstly, injecting or flooding the ethylenediamine disuccinic acid solution into the organic-heavy metal polluted composite soil, and then injecting or flooding the lauryl sodium sulfate solution into the organic-heavy metal polluted composite soil; (2) injecting or flooding water into the polluted soil; and (3) collecting the solutions discharged in the steps (1) and (2) and treating with water scrap iron to realize green repair on the organic-heavy metal polluted composite soil. The polluted composite soil repairing method can be used for carrying out in-situ repair and different-position repair on the soil and has the advantages of simplicity in operation, low cost, no secondary pollution and the like.
