Problems solved by technology

[0004] However, when this device cleans the polluted soil, the high-pressure nozzle sprays out the eluent to mix with the soil. Since the high-pressure nozzle is only installed at the feed inlet, when the soil is rinsed, the soil and the The distance of the spray head is gradually increased, thereby reducing the leaching effect of the eluent on the soil

Embodiment 1

[0047] Embodiment 1: a kind of soil washing equipment, such as figure 1 As shown, it includes a box body 1, four pillars 11 fixed on the bottom of the box body 1 (not limited to four pillars 11), a feed hopper 2 fixed on the top of the box body 1, and a The material receiving box 3 at one end of the hopper 2; the four pillars 11 are scattered at the four corners of the bottom of the box body 1; the inside of the box body 1 is provided with a cleaning channel, and the feeding hopper 2 is connected to the cleaning channel; the box body 1 is far away from the feeding hopper 2 One end is provided with a discharge port 12, and the discharge port 12 faces the material receiving box 3;

[0048] As pictured and figure 2 As shown, a stirring shaft 5 is rotatably connected to the casing 1, the stirring shaft 5 is a hollow structure and one end of the stirring shaft 5 is connected with a driving motor 4, and the other end extends out of the casing 1; the driving motor 4 is fixedly conn...

Embodiment 2

[0057] Embodiment 2: a kind of soil restoration technique, comprises the following steps:

[0058] Step 1. Sampling at one time: Divide the area of ​​contaminated soil, divide the contaminated area into several small areas, and insert pillars at the corners of the boundaries of each area, and connect adjacent pillars through lines; A small area of ​​it is sampled.

[0059] Step 2. Sieving: put the sampled soil into the sieving machine for sieving, so as to classify the size of the soil particles and filter out the stones mixed in the soil.

[0060] Step 3, chemical rinsing: the sub-sieved soil enters the casing 1 of the soil cleaning equipment through the feeding cylinder 21 and the feeding hopper 2. After the chemical agent is configured in the cleaning tank, start the water pump and put the soil in the cleaning tank. The medicament enters the stirring shaft 5, and sprays out from the water outlet in the spiral stirring paddle 51, so that the cleaning liquid contacts the soi...

Abstract

The invention discloses soil cleaning equipment and a soil remediation technology and relates to the technical field of soil remediation. The soil cleaning equipment comprises a tank body, a stirringshaft, a spiral stirring paddle and a driving motor, wherein the spiral stirring paddle is provided with a plurality of water outlets; a discharge opening is formed in one end, away from a feeding hopper, of the tank body; a material receiving box is arranged at the discharge opening formed in the tank body; the discharge opening faces the material receiving box; the plurality of water outlets inthe spiral stirring paddle all spray soil, so that the soil is conveniently cleaned while the soil and leacheate are sufficiently mixed. The soil remediation technology comprises the following steps:step one, sampling; step two, sieving; step three, spraying of leaching pesticide; step four, standing and drying; step five, wastewater treatment; step six, secondary sampling; step seven, backfilling; step eight, remediation of all the soil. After secondary sampling, soil subjected to primary treatment is back filled and marked, so that the soil is easily distinguished.

Description

technical field [0001] The invention relates to the technical field of soil remediation, and more specifically, relates to a soil cleaning device and a soil remediation process. Background technique [0002] Soil remediation is a technical measure to restore the normal function of polluted soil. [0003] The authorized announcement number is CN204799678U, a Chinese utility model patent, which discloses an integrated device for removing soil pollutants by ectopic mixing and leaching, including a drum screening machine, a screw mixer, a hoist, a belt filter press and Control system; the polluted soil is screened by a drum sieving machine; the screened polluted soil is conveyed into the feed inlet of the screw mixer, and the high-pressure liquid spray device on the feed inlet sprays the washing liquid; inside the screw mixer, the polluted The soil and the eluent are fully mixed and washed; the washed soil is lifted to the belt filter press for pressure filtration, and the trea...
