Description

Soil restoration system and restoration method thereof

Technical Field

The invention relates to the field of soil pollution treatment equipment, in particular to a soil remediation system.

Background

Soil pollution can be divided into two major categories, namely inorganic pollutants and organic pollutants, wherein the inorganic pollutants mainly comprise acid, alkali, heavy metal, salts, radioactive element cesium, strontium compounds, arsenic-containing, selenium-containing and fluorine-containing compounds and the like, the organic pollutants mainly comprise organic pesticides, phenols, cyanide, petroleum, synthetic detergents and harmful microorganisms brought by urban sewage, sludge and stable manure, when the soil contains excessive harmful substances, the harmful substances exceed the self-cleaning capacity of the soil, the composition, structure and function of the soil are changed, the microbial activity is inhibited, the harmful substances or decomposition products thereof gradually accumulate in the soil to be absorbed by the human body through the soil, the plant, the human body or the soil, the water and the human body to the extent of endangering the health of the human body, namely the soil pollution, and meanwhile, the polluted soil can be reused by carrying out corresponding soil discharging, soil loosening, applying alkaline fertilizer, ridge turning, water flushing, improving and using chemical improving agents and the like, so that the problem of the soil is solved in the severe soil pollution of the whole world.

Soil remediation systems are organic systems that are specifically designed to remediate contaminated soil, and common equipment includes: soil excavation equipment, soil sorting equipment, soil conveying equipment, medicament mixing and adding equipment, mixing equipment and the like. Existing soil remediation systems have disadvantages including:

1. soil excavation equipment: when the polluted soil is treated, measures such as soil discharge, soil loosening, ploughing and ridging are adopted for treatment, in the process, the polluted soil excavating device is important treatment equipment, and because the polluted soil contains a large amount of wastes and harmful microorganisms, and meanwhile, the polluted soil excavating equipment capable of purifying air and sterilizing is deficient, so that the personal safety of constructors who excavate the polluted soil is endangered, and the working efficiency of the constructors is reduced;

2. soil sorting equipment: in the screening process, dry soil is crushed in a screen frame due to vibration, dust is easily lifted, and the dust is easily scattered to air after screening to pollute the air; when the machine is used for screening, the machine can vibrate relatively with the ground, noise is easy to form, and the working environment is influenced;

3. soil conveying equipment: the polluted soil is crushed and then is conveyed to the stirring equipment through the conveying equipment, the polluted soil is stirred with the medicament in the stirring equipment, the working procedure is troublesome, and a large amount of working time is required for stirring;

4. Medicament mixing and adding equipment: most of the existing dosing equipment is inconvenient in position fixing of a spray header, has limited spraying angles, and is not beneficial to comprehensive purification of polluted soil; the existing contaminated soil remediation and chemical oxidation agent dosing equipment is mainly used for completely mixing chemical oxidation agents with water, then transporting the chemical oxidation agents to the dosing equipment through a series of measures, spraying the internal oxidation agents on the contaminated soil by the dosing equipment to perform chemical reaction with the contaminated soil, but the existing dosing equipment is limited in volume, cannot contain excessive chemical oxidation agents at one time, can continue to work only by adding new chemical oxidation agents repeatedly, is time-consuming and labor-consuming, is low in working efficiency, and can enhance the labor intensity of workers.

5. Mixing equipment: when the mixer is discharged after running, a plurality of dust particles are taken out from the discharge hole, and the soil has pollution, so that the soil can cause considerable pollution to the large environment and even harm the health of nearby people; 2. the height of blendor is higher, inconvenient maintenance when breaking down, and the manual climbing easily falls down, and is not enough safe.
