Detailed Description
The technical solutions of the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any inventive step, fall within the scope of protection of the present invention.
Preferred embodiments of the present invention will be described in detail below.
Referring to fig. 1 to 4, a soil remediation system includes a barrel assembly 30, a bucket assembly 10, a connecting portion 20, and a telescopic rod 40, wherein the barrel assembly 30 and the bucket assembly 10 are connected by the connecting portion, a door 120 is provided at a portion of the bucket assembly 10 connected to the connecting portion 20, the door 120 can be opened and closed in various manners, and a pull rope can be provided at the door 120 and controlled by a control system 50. The door 120 may also be foldable, where the door is made of impact resistant, load bearing material and is controlled by a control system. The door may be of the rail type, either vertical or horizontal.
The connection portion 20 and the cylinder device 30 are connected to each other, the bucket device 10, the connection portion 20 and the cylinder device connection portion are connected to each other, when the bucket device 10 scoops up soil, the telescopic rod 40 lifts the bucket device 10, the control system 50 opens the door, the soil in the bucket device 10 can completely enter the cylinder device 30 through the door via the connection portion due to gravity, and the door 120 is closed after the soil completely enters the cylinder device.
At the same time, the heating system is also in operation, heating the entire cartridge assembly 30. The soil entering the barrel device 30 and the soil remediation agent placed inside the barrel device 30 are heated simultaneously, when the temperature reaches a certain critical temperature, Hg, Se and As heavy metals in the soil volatilize, the heavy metal collector fixed on the inner wall of the barrel device 30 collects the volatilized heavy metals for centralized treatment, and the position of the inner wall of the barrel device 30 is just above the soil and opposite to the position of the second through hole 340.
By selecting natural solar energy for the heating system of the barrel assembly 30, a large amount of energy must be consumed to heat the soil, which can save costs.
The blade 310 is arranged in the barrel device 30, and the blade 310 is detachably fixed on the wall of the barrel device 30. After soil enters the barrel device 30, the control system 30 controls the telescopic rod 40 to enable the soil in the barrel device 30 to roll, the blade 310 can cut some hardened soil and some large pollutants, and the soil, the pollutants and the repairing agent can be fully contacted and completely mixed together through the rolling.
For some pollutants which are difficult to cut and can be left in the cylinder device 30, after all the shredded soil flows out of the holes of the second through hole 340, all the pollutants in the cylinder device 30 can be poured out for centralized treatment by adjusting the angle of the telescopic rod 40. The second through holes 340 may be selected to have a suitable size and number according to the size of the cartridge device 30.
The blades 310 provided in the cartridge device 30 wear out over time and can be replaced and maintained at any time.
The soil remediation agent comprises an organic fertilizer, limestone, a vulcanized sheet and a compound microbial agent. The compound microbial agent comprises photosynthetic bacteria, lactic acid bacteria, sulfurous bacteria, bacillus subtilis and bacteroides fragilis. Through acid-base neutralization treatment, a neutralizing substance, namely a vulcanization tablet and limestone, is added to be mixed with the polluted soil, so that the solubility of the pollutants is reduced, and the activity and toxicity of the pollutants in the environment are reduced. The organic fertilizer is added to achieve the capability of degrading organic pollutants which are difficult to degrade in the soil and enhance the soil fertility. The composite microbial agent and the probiotics are added, so that beneficial floras in the soil are greatly increased, the diversity of soil microbial communities is restored, the air permeability is enhanced, the soil hardening problem is effectively solved, and the soil micro-ecological environment is improved.
Therefore, the scope of the present invention should not be limited to the disclosure of the embodiments, but includes various alternatives and modifications without departing from the scope of the present invention, which is defined by the claims of the present patent application.
