Description

Technical Field

[0001] The present invention relates to the technical field of soil remediation, and in particular to a soil remediation device based on microbial treatment. Background Art

[0002] At present, in order to increase crop yields and income, a large amount of chemical fertilizers and pesticides need to be used, resulting in excessive heavy metals in the soil, serious soil pollution, and the soil is difficult to quickly repair by the natural environment, resulting in pollution accumulation, and then serious soil compaction, poor planting environment, and crop failure. In order to ensure the normal function of the soil and achieve sustainable use of the soil, artificial intervention is usually used to repair the soil.

[0003] The Chinese patent application with publication number CN220216224U discloses a soil remediation device based on microbial treatment. The patent application solves the problem that the crushed soil is not screened, resulting in large impurities still existing in the mixing box, which affects the uniformity of mixing the soil and the microbial agent and easily causes damage to the stirring paddle. In addition, due to gravity, the soil entering the mixing box is easily deposited at the bottom of the mixing box, resulting in the inability to evenly mix the bottom soil with the microbial agent, and thus unable to achieve sufficient and efficient microbial remediation of the soil. However, the above patent still has the following deficiencies when remediating the soil:

[0004] (1) Soil needs to be collected in advance and added to the repair device before soil repair can be carried out. It is not possible to collect soil while repairing, and the repair efficiency is low;

[0005] (2) The microbial solution cannot be sprayed evenly at different depths in the soil and needs to be stirred and mixed, which prolongs the repair time;

[0006] (3) Due to the sedimentation of the microbial solution, the soil at the bottom is often repaired first. When the soil is discharged, it is impossible to control the soil at the bottom to be discharged first;
