Problems solved by technology

In the prior art for soil pollution remediation, the soil composition in the area is improved by covering the surface of the land to be repaired with the new soil, and then manually spraying the repair agent, but the internal impurities of the new soil are more gravel. Therefore, it can only achieve the effect of temporary maintenance, and the restoration agent cannot completely penetrate into the soil layer during the spraying process. Due to the influence of the environment, it is very easy to volatilize into the air, and the restoration effect is average. Therefore, it is necessary to propose a soil pollution restoration Use a multi-layer filter device to solve the above problems

Abstract

The invention discloses a multi-layer type filtering device for soil pollution remediation, which comprises an outer box shell, a support base, an auxiliary grinding assembly, a built-in filtering assembly and a conveying device; the outer box shell is fixedly arranged on the upper end surface of the support base, and a plurality of driving wheels are symmetrically arranged at four corners of thelower end surface of the support base; an auxiliary grinding assembly is vertically arranged on one side of the interior of the outer box shell in a penetrating mode and is used for primarily grindingand refining new soil mud, so that the soil mud enters a built-in filtering assembly in a granular form; a built-in filtering assembly is arranged in the outer box shell and is communicated with theauxiliary grinding assembly, wherein a conveying device is further installed in the outer box shell and conveys filtered soil mud to the outside of the device and evenly disperses the filtered soil mud to cover the ground surface layer of to-be-trimmed soil; therefore, a layer of covering nutrient film is formed on the surface of the land.

Description

technical field [0001] The invention relates to the technical field of treatment and restoration equipment for various contaminated soils in agricultural land, in particular to a multi-layer filter device for soil pollution restoration. Background technique [0002] In recent years, due to population growth and rapid industrial development, solid waste has been continuously piled and dumped on the soil surface, harmful wastewater has continued to seep into the soil, exhaust gas from automobiles, harmful gases in the atmosphere and floating dust have continued to fall into the soil with rain. The improvement of the level of agricultural chemistry has caused a large amount of chemical fertilizers and pesticides to be scattered into the environment, resulting in more and more opportunities for soil to be polluted by non-point sources, and the degree is becoming more and more serious; under the influence of soil erosion and wind erosion, etc., The area of ​​pollution continues t...
