Soil ex-situ remediation system

Abstract

The invention relates to the field of soil pollution treatment equipment and facilities, in particular to a soil ex-situ remediation system. The soil ex-situ remediation system comprises a soil excavation device, a soil sorting device, a soil conveying device, a medicament putting device and a mixing device which cooperate to work to achieve the purpose of soil remediation; and the structural design of all components is reasonable, and the remediation efficiency and effect are greatly improved on the whole.

Description

technical field [0001] The invention relates to the field of soil pollution control equipment, in particular 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, compounds of radioactive elements cesium and strontium, compounds containing arsenic, selenium and fluorine, etc., organic pollutants Pollutants mainly include organic pesticides, phenols, cyanides, petroleum, synthetic detergents, and harmful microorganisms brought 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 It will cause changes in the composition, structure and function of the soil, inhibit microbial activities, and gradually accumulate harmful substances or their decomposition products in the soil through "soil→plant→human bo...

AI Technical Summary

Problems solved by technology

[0004] 1. Soil excavation equipment: At present, most of the devices for ectopic repair of soil are original devices, such as excavators, and the excavation depth control of excavators is not precise, relying on experience to excavate soil, and can only complete the excavation action , so the efficiency is extremely low;

[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
