Soil pollution remediation device

[0026] see Figure 1-5 , a soil pollution remediation device, comprising a base 6 and an outer shell 1 arranged on the base 6, a funnel-shaped opening 2 is arranged above the outer shell 1, and the opening 2 is connected to a separation chamber 3 provided in the outer shell 1 Connected, one side of the outer casing 1 is provided with a feeding pool 7, and a first conveyor belt 8 is provided between the feeding pool 7 and the opening 2, and the contaminated soil placed in the feeding pool 7 can be transported through the first conveyor belt 8 In the opening 2, a crushing mechanism 9 is provided above the separation chamber 3, and the soil entering the separation chamber 3 can be crushed by the crushing mechanism 9. A separation dragon 14 is arranged obliquely in the separation chamber 3, and the separation chamber The bottom surface of 3 is parallel to the separation dragon 14 and there is a certain gap between the bottom surface of the separation chamber 3 and the separation drag

[0034] This embodiment is further improved on the basis of Embodiment 1, and the improvement is that: the microbial repair granule 11 includes a microbial layer 38, a nutrient layer 37 and a water-soluble protective layer 36, and the microbial layer 38 is wrapped around the nutrient layer 37 , the nutrient substance layer 37 is wrapped with a water-soluble protective layer 36. When the microbial remediation particles 11 are mixed with the soil with moisture, the water-soluble protective layer 36 melts, so that the microbial layer 38 and the nutrient substance layer 37 are mixed with the soil. The microorganisms contained in the layer 38 degrade the organic pollutants in the soil, while the nutrient substance layer 37 can not only increase the reproduction speed of the microorganisms, but also make the soil more fertile.
