The active agents for remedying the toxicity of soil are mainly classified into biological surfactants and non-biological surfactants. The non-biological surfactant is usually sodium dodecyl benzene sulfonate, sodium dodecyl sulfate and the like, has certain toxicity to plant growth and is not beneficial to further treatment of recovered soil, and compared with the biological surfactant, the biological surfactant has the characteristics of low toxicity, biodegradability and the like. Sophorolipid is a typical biological surfactant, is produced by microbial fermentation, has easily available raw materials, not only has the general property of the conventional surfactant, but also has the characteristics of no toxicity and 100 percent biodegradability.

The specific implementation process is as follows:
in the process of spraying the sophorolipid compound, the sprayed substance is the sophorolipid compound in the technical scheme, and for the spraying of the sophorolipid compound, the problem of the viscosity of the glycolipid compound in the spraying process needs to be solved, and the problem that the kinetic energy provided by a pressure device for the sophorolipid compound substance in the spraying process is insufficient is solved, so that the viscosity is relieved in the technical scheme that the sophorolipid compound flowing from the storage layer 1 to the outflow channel 6 is cut by the aid of the self-rotation mode of the rotating layer 2 through the inclined teeth 4, the acute angle of the inclined teeth 4 is used for facilitating the cutting, and the inclined teeth 4 are gradually widened, so that the sophorolipid compound flows along the inclined teeth 4, and the sophorolipid compound is collected to the flow channel 7 at fixed points. Thereby avoiding the blocking of the channel by the agglomerated viscous sophorolipid compound, and simultaneously reducing the volume of the sophorolipid compound, so as to facilitate the ejection of the single-flow sophorolipid compound and maintain the ejection speed and distance of the sophorolipid compound.
Rotate layer 2 and carry out the rotation to the skewed tooth 4 that drives and rotate layer 2 body coupling rotates, forms quick air current in rotatory notch 5 when skewed tooth 4 is rotatory, because the formation of quick air current, thereby form the negative pressure space in making rotatory notch 5, with the suction of the sophorolipid complex of storage layer 1, thereby solve the consistency of sophorolipid complex, flow the sophorolipid complex, be convenient for combine the effect of gravity to transport the sophorolipid complex. Therefore, the device cuts the sophorolipid compound, utilizes the pneumatic nozzle 9 to spray out the sophorolipid compound small groups, and falls to a specified place to improve the soil.
Compared with the prior art of conglobation ejection, the technical scheme is free of continuous ejection pressure, so that the sophorolipid compound is required to fall on different falling points to realize the coverage of the spraying range, at the moment, the conglobation sophorolipid compound performs parabolic motion due to different heights of the discharge ports 8, the linear distance of the sophorolipid compound is changed by utilizing the different heights of the discharge ports 8, the different falling points are realized, and in addition, the rotating part rotates to perform the coverage of the sophorolipid compound in a range manner, so that the problem that the coverage can not be continuously sprayed in a linear manner is solved.
Example two
The difference between the technical scheme and the above embodiment is that the sophorolipid compound for improving soil disclosed in the embodiment comprises the following components: sophorolipid, NaCl, ethylenediamine tetraacetic acid, diethyl aminoethyl hexanoate, konjac glucomannan and water, wherein the proportion of the sophorolipid, the NaCl, the ethylenediamine tetraacetic acid, the diethyl aminoethyl hexanoate, the konjac glucomannan and the water is 4:1:2:2:2: 6.
(1) Screening out a better oil-containing soil cleaning process: through a single-factor experiment, the scheme for cleaning the oil-containing soil is determined under the formula: the liquid-solid ratio is 2: 1, the temperature is 35 ℃, the stirring speed is 600r/min, the cleaning time is 20min, and the soil crude oil removal rate can reach 92.31 percent at the highest under the condition.
(2) The scale amplification experiment and the repeated use experiment show that the removal rate of the crude oil can be kept above 90% by amplifying the oil-containing soil to 300 times.
(3) The oil sample density and ash content of the recovered oil sample treated by the sophorolipid compound are slightly increased compared with those of the original oil sample, the content of saturated components is increased, the contents of aromatic components, colloid and asphaltene are reduced, the viscosity is reduced, and the recovered crude oil has a certain utilization value.
(4) Compared with the original unpolluted soil, the soil after the sophorolipid compound remediation has the advantages that the organic matter content of the soil is slightly increased, the pH is reduced to 7.46 from 8.53, the total salt content is reduced to 0.24 from 1.51%, and the soil grade is reduced from severe saline-alkali soil to mild saline-alkali soil.
Referring to fig. 4, the residual toxicity of the restored soil is examined through a seed germination growth experiment, and the restored soil is found to promote the germination and growth of ryegrass and alfalfa, and the results show that: the toxicity of the soil after the sophorolipid compound is repaired is effectively controlled.
