Embodiment 1

[0035] The invention discloses a soil remediation technology. A soil remediation agent is added to polluted soil. The soil remediation agent is mixed with the following components: ammonium persulfate, sodium hypochlorite, cetyltrimethylammonium bromide, polyaniline, three Methylol propane oleate, humic acid, catalyst, nano-aluminum trioxide, citric acid, sawdust, sunflower seed hulls and stearyl phosphate; the contents of each component are shown in Table 1 below.

Embodiment 2

[0037] The invention discloses a soil remediation technology. A soil remediation agent is added to polluted soil. The soil remediation agent is mixed with the following components: ammonium persulfate, sodium hypochlorite, cetyltrimethylammonium bromide, polyaniline, three Methylolpropane oleate, humic acid, catalyst, nano-aluminum trioxide, citric acid, sawdust, sunflower seed hulls and stearyl phosphate; the difference from Example 1 is that the contents of each component are as shown in Table 1 below Show.

Embodiment 3

[0039] The invention discloses a soil remediation technology. A soil remediation agent is added to polluted soil. The soil remediation agent is mixed with the following components: ammonium persulfate, sodium hypochlorite, cetyltrimethylammonium bromide, polyaniline, three Methylolpropane oleate, humic acid, catalyst, nano-aluminum trioxide, citric acid, sawdust, sunflower seed hulls and stearyl phosphate; the difference from Example 1 is that the contents of each component are as shown in Table 1 below Show.

Abstract

The invention relates to the technical field of soil remediation, and discloses a soil remediation technology, a soil remediation agent is added to contaminated soil, and the soil remediation agent comprises the following components by weight: 20-30 parts of ammonium persulfate; 15 to 20 parts of sodium hypochlorite; 4 to 6 parts of hexadecyl trimethyl ammonium bromide; 6 to 8 parts of polyaniline; 8 to 12 parts of trimethylolpropane oleate; 2-3 parts of humic acid; 6-8 parts of catalyst. The soil remediation technology has the following advantages and effects: ammonium persulfate and sodium hypochlorite are jointly added as oxidants; hexadecyl trimethyl ammonium bromide is added to improve the physical and chemical properties of the soil; trimethylolpropane oleate is mixed with soil to form organic clay; polyaniline and trimethylolpropane oleate generate a synergistic effect to improve the adsorbability of organic pollutants, so that the capacity of adsorbing and fixing the organic pollutants by soil can be improved, the accumulated organic pollutants can be conveniently converted into non-toxic or relatively low-toxicity substances by an oxidizing agent, and the oxidation effectis improved to achieve the purpose of repairing the soil.

Description

technical field [0001] The invention relates to the technical field of soil restoration, in particular to a soil restoration technology. Background technique [0002] Soil remediation is a technical measure to restore the normal function of polluted soil. In the soil remediation industry, there are more than one hundred existing soil remediation technologies, and there are more than ten commonly used technologies, which can be roughly divided into three methods: physical, chemical and biological. It usually refers to the transfer, absorption, degradation and transformation of pollutants in the soil by physical, chemical and biological methods, reducing its concentration to an acceptable level, or converting toxic and harmful pollutants into harmless substances. Fundamentally speaking, the technical principles of contaminated soil remediation can include: (1) changing the form of pollutants in the soil or the way they combine with the soil to reduce their mobility and bioava...
