Novel intelligent ex-situ soil remediation system

Abstract

The invention discloses a novel intelligent ex-situ soil remediation system which comprises an excavation area, a construction waste temporary storage area, a clean soil to-be-detected area, a water storage and supply system and a chemical storage and supply system. The water storage and supply system and the chemical storage and supply system are arranged in a closed-loop rail, and a transportation remediation unit is arranged on the closed-loop rail. The transportation remediation unit runs along a track path and is used for transporting soil and remediating the soil; the excavation area, the construction waste temporary storage area and the clear soil to-be-detected area are arranged on the periphery of the closed-loop rail. Through the arrangement, the environmental safety management problem, the secondary pollution prevention and control problem, the construction efficiency problem and the construction cost management and control problem of the ex-situ remediation technology are effectively solved.

Description

technical field [0001] The invention relates to the technical field of contaminated soil remediation, in particular to a novel intelligent off-site soil remediation system. Background technique [0002] Contaminated site remediation technology can be divided into in-situ remediation technology and ex-situ remediation technology according to the remediation method. Ex-situ remediation technology refers to excavating polluted soil from the polluted location, and remediation within the scope of the original site or after transportation. Governance technology. Ex-situ remediation technology is widely used, and is generally applicable to sites with high pollution concentration, high risk and low excavation risk. During the implementation of traditional ex-situ remediation technology, the contaminated soil is repeatedly transported between the polluted area and the treatment area, which requires more investment in mechanical equipment and over-reliance on manual command and assis...

AI Technical Summary

Problems solved by technology

[0003] 1. The transportation process is complicated, resulting in high investment density of mechanical equipment and serious consumption of human resources. That is, a large number of diesel engineering machinery is repeatedly transported between excavation areas, transfer soil pile areas, soil restoration areas, and soil waiting areas, which consumes a lot cost, manpower and material resources;

[0004] 2. The risk of secondary pollution during transportation and operation is high, and the investment in environmental management is relatively high;

[0005] 3. The transportation and repair operation machinery is greatly affected by weather and other factors, and has a strong dependence on the construction road; there are many safety hazards in site operations;

[0006] 4. The degree of intelligence is low, relying on manual management, which restricts the construction efficiency

[0008] The patent with publication number CN101357369A describes a system and treatment method for ectopic remediation of soil with volatile organic pollution. The contaminated soil is treated by using a closed soil remediation bed and supporting treatment equipment such as an air induction system. The system is a fixed Treatment, does not have the ability to move, it is only suitable for fixed treatment of volatile organic compound contaminated soil, the application flexibility is insufficient and traditional diesel mechanical equipment is required for transportation and repair operations

[0009] The patent with the publication number CN107716541A describes a modular movable heterotopic soil remediation system, which uses a wheeled platform for movement. It does not have soil transportation capacity and its wheeled platform depends on the transportation road conditions. Site application is relatively limited
