Embodiment 1

[0053] Step 1: prepare the main pipeline 1 and the auxiliary pipeline 2, arrange the device components, arrange the hot air pump unit 3 and the treatment liquid unit 4 on one side of the pretreatment odorous soil, and arrange the purification device 5 on the other side, and before repairing, install the Collect soil gas samples at the boundary of the area to be repaired and inside the area with odorous soil, and detect the odor concentration before restoration;

[0054] Step 2: Bury the auxiliary pipes 2 at equal intervals in the pretreated odorous soil, pass the main pipe 1 through the middle of the connecting rod of each auxiliary pipe 2, and align the connecting groove 13 with the inner layer 21 of the auxiliary pipe 2 for clamping. After connecting, slide stopper 254, pull out plastic film 252, plastic film 252 is elongated and unfolded, and the patch 253 on each secondary pipeline 2 expansion device 25 is connected with the patch on the adjacent secondary pipeline 2 expans...

Embodiment 2

[0061] The processing method and device of this embodiment are basically similar to Embodiment 1, the main differences are:

[0062] Step 4: (1) Inject the treatment liquid for 2 hours, (2) Inject hot steam for 2 hours, (3) Repeat Step 4 (1)-(2) for 3 times.

Embodiment 3

[0064] The processing method and device of this embodiment are basically similar to Embodiment 1, the main differences are:

[0065] Step 4: (1) Inject the treatment solution for 1.5 hours, (2) Inject hot steam for 1.5 hours, (3) Repeat Step 4 (1)-(2) cycle 4 times.

Abstract

The present invention relates to a treatment device and method for deodorizing soil, wherein the treatment device for deodorizing soil includes a main pipeline arranged on the surface of the pretreated odorous soil, an auxiliary pipeline that goes deep into the pretreated odorous soil, and is set in the pretreatment The hot air pump unit on the soil side is used to inject hot steam into the manifold, the treatment liquid unit installed on the side of the hot air pump unit is used to inject treatment liquid into the gas injection manifold, and the outlet of the main pipeline Purification device, a kind of odor removal treatment method for odorous soil of the present invention, removes the odor in the odorous soil by injecting water and gas into the laid manifold, and at the same time establishes a cycle to purify the treated water and then recycle it. Utilization, the peculiar smell in the soil is mixed and taken out by the hot steam and then adsorbed, which improves the efficiency of soil peculiar smell treatment and reduces secondary pollution.

Description

technical field [0001] The invention relates to the technical field of peculiar smell soil treatment, in particular to a treatment device and method for removing peculiar smell from peculiar smell soil. Background technique [0002] At present, my country's soil environment is generally not optimistic. The soil pollution rate is high and the polluted area is increasing, which has a huge impact on the growth of animals and plants, especially crops. Among them, the problem of odorous soil remediation has gradually attracted people's attention. The discharge of industrial wastewater and the burial of domestic waste will cause serious soil odor and affect people's production and life. Existing soil odor treatment can be divided into in-situ and ex-situ. The traditional ex-situ treatment will violently disturb the odorous soil during excavation and transportation, and the amount of irritating odor it emits will increase. In-situ treatment usually adopts electric restoration , So...
