Embodiment 1

[0033] A kind of soil washing solution provided by the invention comprises: solute and solvent, wherein solute comprises p-methoxyphenol, potassium persulfate, oxalic acid, aluminum triacetylacetonate, magnesium sulfate heptahydrate, solvent is water, according to mass percentage, Its p-methoxyphenol is 5.4-5.8%, potassium persulfate is 2.2-2.8%, and oxalic acid is 1-2%. The solute also includes ethylenediaminetrisuccinic acid, wherein the mass percentage of ethylenediaminetrisuccinic acid is 0.8-1.2%. Wherein the mass percent of magnesium sulfate heptahydrate is 5-6%. Wherein the mass percentage of aluminum triacetylacetonate is 1-2%.

Embodiment 2

[0035] The invention also discloses a method for using the soil washing liquid, comprising the following steps:

[0036] 1) Pulverize the contaminated soil;

[0037] 2) Sieve the crushed contaminated soil to obtain fine-grained soil with a particle size less than 3cm;

[0038] 3) Put the fine-grained soil into the soil eluent treatment equipment, add water equal to 1 / 2 to 1 / 3 of the weight of the soil, and stir to push the soil to turn;

[0039] 4) Add soil eluent, stir and turn over to mix, and the amount of eluent added is 1 to 2 times the weight of the soil;

[0040]5) Separate and take out the soil after fine treatment and the soil after coarse treatment.

Embodiment 3

[0042] Such as figure 1 , figure 2 , image 3 As shown, the present invention also discloses a soil washing liquid treatment equipment applied in the method of using the soil washing liquid, which includes a horizontal tank 1 and a horizontally arranged rotating shaft 2, and the rotating shaft is externally connected to a drive motor 3 ; The horizontal tank body has a primary treatment area 4 close to the drive motor side and a secondary separation area 5 on the other side; the rotating shaft is equipped with a propeller-shaped horizontal drive blade 6 for driving the soil by a The primary treatment area turns over and enters the secondary separation area; the horizontal driving blade is positioned on the rotating shaft on one side of the primary processing area; Turn the soil at the bottom into the upper layer to mix with the soil eluent. The turning blade is an arc-shaped blade extending radially from the rotating shaft; the upper part of the secondary separation area has...

Abstract

A kind of soil washing liquid provided by the present invention comprises: solute and solvent, wherein solute comprises p-methoxyphenol, potassium persulfate, oxalic acid, solvent is water, and its p-methoxyphenol 5.4-5.8% according to mass percentage , potassium persulfate 2.2‑2.8%, oxalic acid 1‑2%. The present invention uses p-methoxyphenol to absorb organic pollutants in the soil through chemical reactions, and combines them with a new high-efficiency full-functional soil repair agent through chemical bonds to remove pollutants and increase effective organic matter in the soil. At the same time, potassium persulfate and oxalic acid can absorb heavy metals in the soil. Using oxalic acid can adjust the pH of the soil washing solution, making it easier for p-methoxyphenol to combine with organic pollutants to achieve the best In addition, the excess part can be used as nutrients to improve the fertility of the soil, which solves the defects that the existing soil eluent treatment has a small application range and the recycled soil cannot be used for cultivation.

Description

technical field [0001] The invention relates to the field of soil treatment, in particular to a soil washing liquid, a use method and equipment. Background technique [0002] At present, with the modernization of agriculture, especially the improvement of the level of agricultural chemicalization, a large amount of chemical fertilizers and pesticides are scattered into the environment, and there are more and more opportunities for soil to suffer from non-point pollution, and its degree is also becoming more and more serious. Under the influence of soil erosion and wind erosion, the polluted area is constantly expanding. According to the nature of pollutants, soil pollutants are divided into two categories: inorganic substances and organic substances: inorganic substances mainly include heavy metals such as mercury, chromium, lead, copper, zinc, and non-metals such as arsenic and selenium; organic substances mainly include phenols, organic pesticides, oils, benzopyrene and d...
