Problems solved by technology

[0003] Existing soil treatment methods are mainly by mixing the soil treatment agent with the contaminated soil and then laying it directly on the plot to be treated, or directly spraying or pouring the liquid treatment agent on the surface of the plot with treatment; in the above methods, all will be due to The uneven distribution of the treatment agent and the shallow treatment depth reduce the treatment effect

Embodiment 1

[0044] Such as Figure 1~2As shown, the present invention provides a kind of soil heavy metal treatment device, comprising:

[0045] Car body 10; at least two excavating and conveying plows 20, which are arranged side by side and spaced below the car body, the two excavating and conveying plows are arc-shaped metal sheets with pointed ends, and the tail ends of the arc-shaped metal sheets Wound into a cylindrical shape to form a conveying channel in the axial direction of the excavating conveying plow; through the rotating shaft 201, at least two excavating conveying plows are driven to rotate upwards or downwards as a whole to adjust the relative height between their tips and the ground; at least Two spiral conveying cylinders 30, one end of which is connected to the tail end of the arc-shaped metal sheet body, the other end of the spiral conveying cylinder is extended to the obliquely above the vehicle body; the mixing box 40 is arranged on the vehicle body, and the The mix...

Embodiment 2

[0054] The method of using the above-mentioned soil heavy metal treatment device to control heavy metal pollution is as follows:

[0055] Step 1, deep digging of the land to be processed, the depth of digging is 0.4-0.45m;

[0056] Step 2, using at least two excavating and conveying plows of the soil heavy metal treatment device to dig deep strip trenches at a certain distance, and pour a certain amount of heavy metal treatment solution through at least two nozzles, calculated according to the area of ​​heavy metal soil to be treated, heavy metal The amount of treatment solution is 2L / m 2 ; The soil excavated in the strip ditch is mixed with the heavy metal control composition according to the mass ratio of 5:1 to obtain the mixture, which is set aside;

[0057] Step 3, using at least two soil plows of the soil heavy metal treatment device to shallowly turn the ground between the strip trenches, bury the strip trenches and level the ground;

[0058] Step four, spread the mix...

Embodiment 3

[0066] The method of using the above-mentioned soil heavy metal treatment device to control heavy metal pollution is as follows:

[0067] Step 1, deep digging of the land to be processed, the depth of digging is 0.45-0.50m;

[0068] Step 2, using at least two excavating and conveying plows of the soil heavy metal treatment device to dig deep strip trenches at a certain distance, and pour a certain amount of heavy metal treatment solution through at least two nozzles, calculated according to the area of ​​heavy metal soil to be treated, heavy metal The amount of treatment solution is 3L / m 2 ; The soil excavated in the strip ditch is mixed with the heavy metal control composition according to the mass ratio of 5:1 to obtain the mixture, which is set aside;

[0069] Step 3, using at least two soil plows of the soil heavy metal treatment device to shallowly turn the ground between the strip trenches, bury the strip trenches and level the ground;

[0070] Step four, spread the mi...

Abstract

The invention discloses a soil heavy metal treatment device and treatment method. The soil heavy metal treatment device comprises a vehicle body, at least two soil digging conveying ploughs, at leasttwo screw conveying barrels, a mixing box, a first feeding port and a second feeding port, multiple discharging ports, a distributor, a storage box, at least two soil turning ploughs and a liquid storage box. The soil heavy metal treatment device can spray a heavy metal treatment liquid according to quantity in deeper positions of heavy metal soil while turning, cover the surface layer of turned soil with a soil layer containing heavy metal treatment composition so as to deeply treat the heavy metal contaminated soil by layers and improve the treatment effect effectively. According to the soilheavy metal treatment method, on the basis of the soil heavy metal treatment device, the proper heavy metal treatment liquid and heavy metal treatment composition are provided, so that the soil treatment effect is further improved.

Description

technical field [0001] The invention relates to the technical field of contaminated soil treatment, in particular to a soil heavy metal treatment device and treatment method. Background technique [0002] Soil heavy metal pollution refers to the addition of metals to the soil due to human activities, mainly mercury, arsenic, lead, chromium, cadmium, etc. These heavy metals pollute the soil, causing the heavy metals in the soil to be significantly higher than the original content, and causing deterioration of the quality of the ecological environment Soil heavy metal pollution not only reduces soil productivity and reduces food production, but also accumulates in plants and animals and enters the food chain, or enters the human respiratory tract through polluted air, and interacts strongly with proteins and enzymes after entering the human body , make them inactive, and may also accumulate in some organs of the human body and endanger health. [0003] Existing soil treatment...
