Sustainable soil remediation system and remediation method thereof

Abstract

The invention discloses a sustainable soil remediation system, belonging to the technical field of soil remediation. The system comprises a water collecting tank, a leaching device, a new soil layer,a waste water treatment device, a waste gas treatment device and a recharge device; the water collecting tank is arranged around the soil to be repaired and communicated, the tank is deep to the underground water level and below the soil to be repaired, the surface is sealed by a cover plate and is provided with a drainage port and an air extraction port, the drainage port is connected with a waste water treatment device through a drainage pump, and the air extraction port is connected with the waste gas treatment device through an air extraction pump; the leaching device consists of a transverse surface pipeline distributed on the surface of the soil to be repaired and a vertical surface liquid inlet pipe threaded with the transverse surface pipeline, wherein the bottom of the transversesurface pipeline is provided with a plurality of liquid outlets; the new soil layer is non-polluted soil, which covers on the transverse pipeline, and the liquid inlet pipe passes through the new soillayer; the recharge device recharges water to the soil outside the water collecting tank to prevent the soil outside from settling. The invention continuously repairs the contaminated soil and controls the ground subsidence while meeting the requirement that the contaminated soil area is used.

Description

technical field

[0001] The invention belongs to the technical field of soil remediation, and in particular relates to a soil remediation system and a remediation method thereof, which enable the area where the soil is located to be quickly used and sustainably remediate the soil. Background technique

[0002] Soil remediation is a technical measure to restore the normal function of polluted soil. In the soil remediation industry, there are more than one hundred existing soil remediation technologies, and there are more than ten commonly used technologies, which can be roughly divided into three methods: physical, chemical and biological; Restoration techniques.

[0003] Among them, the in-situ remediation technology is the process of treating unexcavated soil without much disturbance to the soil, but it is difficult to deal with the three wastes (waste water, waste gas, fixed waste) in the soil; while the ex-situ remediation technology often requires a large amount of Exca...

Examples

Embodiment Construction

[0024] The soil remediation system and remediation method of the present invention will be fully described in conjunction with specific embodiments, so that those skilled in the art can fully understand and implement them.

[0025] As shown in the figure, a sustainable soil remediation system includes a sump 1, a washing device 2, a new soil layer 3, a waste water treatment device 4, a waste gas treatment device 5 and a refilling device 6; the sump 1 is arranged on The soil to be repaired is surrounded and connected, the depth of the groove is below the groundwater level and the soil to be repaired, and it is supported and fixed by the support system. The surface of the sump 1 is sealed by the cover plate 7 and is provided with a drainage port and an air suction port; The pump 8 is connected to the waste water treatment device 4, and the air suction port is connected to the waste gas treatment device 5 through the air pump 9; the rinsing equipment 2 is composed of a horizontal ...
