一种突发性对甲基苯酚污染土壤的修复方法

Remediation method of soil contaminated by p-methyl phenol suddenly

Abstract

The invention belongs to the field of soil remediation and discloses a remediation method of soil contaminated by p-methyl phenol suddenly. The remediation method comprises the following steps: (1) removing the soil contaminated by p-methyl phenol suddenly, putting the soil into a bioreactor, and adding pure water at the temperature of 60-70 DEG C into the bioreactor; (2) stirring the components in the bioreactor at the stirring speed of 30r/min for 50 minutes; (3) adding dioctyl sodium sulfosuccinate and dodecyl polyglucoside, stirring further at the stirring speed of 30r/min for 40 minutes; and (4) stopping stirring, decreasing the temperature in the bioreactor to room temperature, separating the soil, and drying the soil to obtain the remediated soil. The remediation method disclosed by the invention has the characteristics of high remediation speed and high remediation efficiency.
本发明属于土壤修复领域,公开了一种突发性对甲基苯酚污染土壤的修复方法,包括以下步骤:(1)将被对甲基苯酚突发性污染的土壤进行移除,将上述的对甲基苯酚污染的土壤置于生物反应器中,向其中加入温度为60-70℃的纯水;(2)对生物反应器内成分进行搅拌,搅拌转速为30r/min,搅拌时间为50min;(3)加入琥珀酸二异辛酯磺酸钠和十二烷基葡萄糖苷,加入后继续搅拌,搅拌转速为30rpm,搅拌时间为40min;(4)停止搅拌,降低生物反应器内温度为室温,分离后,将土壤干燥,为修复后的对甲基苯酚污染土壤。本发明的土壤修复方法具备了修复速度快、修复效率高的特点。
