Soil repairing system and repairing method thereof

Abstract

The invention relates to the field of soil pollution treatment facilities, and in particular relates to a soil repairing system which comprises a soil digging device, a soil separation device, a soil conveying device, a chemical feeding device and a mixing device. By virtue of the cooperation of the five parts, the purpose of soil repairing is achieved, the structures of different parts are reasonably designed, and the repairing efficiency and the repairing effects are greatly improved as a whole.

Description

Technical field [0001] The invention relates to the field of soil pollution treatment equipment, and particularly relates to a soil restoration system. Background technique [0002] Soil pollution can be roughly divided into two categories: inorganic pollutants and organic pollutants. Inorganic pollutants mainly include acids, alkalis, heavy metals, salts, radioactive elements cesium, strontium compounds, arsenic, selenium, and fluorine-containing compounds, etc. Pollutants mainly include organic pesticides, phenols, cyanide, petroleum, synthetic detergents, and harmful microorganisms caused by urban sewage, sludge and manure. When the soil contains too many harmful substances and exceeds the self-purification capacity of the soil, It will cause changes in the composition, structure and function of the soil. Microbial activities will be inhibited. Harmful substances or their decomposition products will gradually accumulate in the soil and be absorbed indirectly by the body throug...

Problems solved by technology

[0004] 1. Soil excavation equipment: When treating polluted soil, measures such as dumping soil, loosening soil, plowing and drying ridges are often used for treatment. During this process, the polluted soil excavation device is an important treatment equipment. Because the polluted soil contains a large amount of waste and harmful microorganisms, and produces a pungent odor, there is a lack of polluted soil excavation equipment that can purify the air and sterilize bacteria, which is harmful to the personal safety of the construction workers who excavate the polluted soil. At the same time It will also reduce the work efficiency of construction workers;

[0005] 2. Soil sorting equipment: During the screening process, the dry soil is crushed by vibration in the screen frame, which is easy to raise dust, and it is easy to float into the air after screening, polluting the air; Vibration, easy to generate noise and affect the working environment;

[0006] 3. Soil conveying equipment: After the polluted soil is pulverized, it needs to be transported to the mixing equipment through the conveying equipment. The contaminated soil is mixed with the chemical agent in the mixing equipment. The process is troublesome, and the mixing requires a lot of working time;

[0007] 4. Drug mixing and adding equipment: most of the existing dosing equipment is inconvenient to fix the position of the spray head, and the spraying angle is limited, which is not conducive to the comprehensive purification of polluted soil; most of the existing dosing equipment for repairing polluted soil is to mix the chemical oxidant with the water body completely , and then transported to the dosing equipment through a series of measures, and then the dosing equipment sprays the internal oxidant on the polluted soil to have a chemical reaction with it. However, the existing dosing equipment is limited in size and cannot accommodate too much chemical oxidant at one time. New chemical oxidants need to be added back and forth to continue working, which is time-consuming, labor-intensive, low-efficiency, and increases the labor intensity of the staff

[0008] 5. Mixing equipment: When the mixer is running, there will be a lot of dust particles brought out from the outlet. Because the soil is polluting, it will bring considerable pollution to the environment, and even harm the surrounding area. The health of personnel; 2. The height of the mixer is high, it is inconvenient to maintain when a failure occurs, and manual climbing is easy to fall, which is not safe enough
