Embodiment 1

[0036] Such as figure 1As shown, the soil remediation system provided by the embodiment of the present invention includes: a sampling device 1, a syringe 2, a pollution detection module 3 and an early warning module 4. The sampling device 1 is provided with a gas outlet and a drug inlet, and the syringe 2 is provided with a drug outlet. , the pollution detection module 3 is provided with a gas inlet, the gas outlet of the sampling device 1 is in fluid communication with the gas inlet of the pollution detection module 3, the signal input end of the pollution detection module 3 is connected with the signal input end of the early warning module 4, and the early warning module 4 The signal output end is connected to the signal input end of the syringe 2 , and the medicine outlet of the syringe 2 is in fluid communication with the medicine inlet of the sampling device 1 .

[0037] Specifically, after the sampling device 1 is inserted into the soil, the gas in the soil is transmitte...

Embodiment 2

[0048] Such as Figure 8 As shown, in the soil remediation method provided by the embodiment of the present invention, the soil remediation system provided in Embodiment 1 is applied, and the sampling device 1 is inserted into the soil of a known polluted site or a site to be monitored.

[0049] The soil remediation method is applicable to the pollution remediation of the leftover site after relocation and the soil pollution monitoring of the plant site in the trial operation.

[0050] Taking the soil remediation and monitoring of gas stations as an example, the soil remediation method includes the following steps:

[0051] Sampling devices 1 are arranged in the soil at intervals along the oil tank area 5 and the oil pipeline 6;

[0052] The distance between two adjacent sampling devices 1 is less than or equal to 3m, and the drill bit 11 is located 3m-6m below the surface, and the distance between two adjacent sampling devices 1 can be adjusted appropriately according to the...

Abstract

The invention provides a soil remediation system and a soil remediation method, and relates to the technical field of environmental protection. The soil remediation system provided by the invention comprises a sampling device, an injector, a pollution detection module and an early warning module, wherein a gas outlet of the sampling device is in fluid communication with a gas inlet of the pollution detection module, a signal input end of the pollution detection module is connected to a signal input end of the early warning module, a signal output end of the early warning module is connected toa signal input end of the injector, and a medicament outlet of the injector is in fluid communication with a medicament inlet of the sampling device. The soil remediation system and the soil remediation method can realize simultaneous sampling monitoring and injection repair, which can not only provide daily monitoring and soil pollution risk management, but also solve the traditional inefficiency problem of soil pollution control through excavation and backfilling.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to a soil restoration system and a soil restoration method. Background technique [0002] With the acceleration of urbanization in China, many smelting and chemical enterprises in urban areas need to be relocated or incorporated into industrial parks. For the development and utilization of sites left after relocation, soil treatment and restoration have become difficult issues. [0003] At present, soil pollution remediation technologies are divided into physical remediation, chemical remediation, biological remediation and phytoremediation in principle, and in-situ remediation and ex-situ remediation in terms of operation space. [0004] The currently used soil sampling methods are designed to meet the needs of site quality assessment. Most of them are one-time sampling, which does not require repeated monitoring at the same monitoring point on a regular basis. It ...
