Contaminated soil remediation machine and contaminated soil remediation method

Abstract

The invention relates to a contaminated soil remediation machine and a contaminated soil remediation method. The machine comprises a remediation box, a crushing box and a partition plate. A crushing chamber and a remediation chamber are defined by the upper surface and the lower surface of the partition plate and the inner wall of the remediation box correspondingly. The crushing box is arranged in the crushing chamber. Feed holes are formed in the top wall of the remediation box and the top wall of the crushing box. Discharge holes are formed in the bottom wall of the crushing box and the side wall of the partition plate. A multi-stage soil crushing assembly is arranged in the crushing box. A spraying chamber is defined between the outer wall of the crushing box and the inner wall of theremediation box, a plurality of spraying holes are evenly distributed in the side wall of the crushing box, and a primary spraying assembly for spraying a remediation agent to the spraying holes is arranged in the spraying chamber. A soil grinding assembly is arranged on the bottom wall of the partition plate, and a secondary spraying assembly for spraying the remediation agent to the soil grinding assembly is arranged on the bottom wall of the partition plate. A stirring assembly for stirring soil and the remediation agent is arranged in the remediation chamber. By crushing and grinding the soil for multiple times, the contact area of the remediation agent and the soil is increased, and the remediation effect is improved.

Description

technical field [0001] This application relates to the technical field of soil remediation, more specifically, it relates to a polluted soil remediation machine and a polluted soil remediation method. Background technique [0002] With the total discharge of inorganic pollutants and organic pollutants in the environment, the form of soil pollution is becoming more and more serious. Soil pollution not only affects the quantity and quality of agricultural products, but also affects the quality of the air and water environment, and can endanger animals through the food chain. and human life and health. [0003] Soil pollution needs to be repaired. Soil remediation is a technical measure to restore the polluted soil to normal functions. Soil remediation refers to the use of physical, chemical and biological methods to transfer, absorb, degrade and transform pollutants in the soil to reduce its concentration. To reduce to an acceptable level, or to convert toxic and harmful poll...

Problems solved by technology

[0004] At present, the existing restoration of soil usually repairs the contaminated soil by artificial spraying of restoration agents. Since there are many contaminated soils to be repaired, artificial spraying is labor-intensive and low in restoration efficiency, and it only affects the soil. The repair agent is sprayed on the surface of the soil, so that the surface of the soil can only absorb the repair agent, the repair range is single, and the repair effect is poor
