Description

Technical Field

[0001] The present invention relates to the field of soil microbial remediation, and in particular to intelligent soil microbial remediation equipment and a remediation method thereof. Background Art

[0002] In recent years, with the rapid development of industrialization in my country and the widespread use of chemical fertilizers and pesticides in agricultural production, large amounts of heavy metals, organic matter, and other pollutants have entered the soil environment through various pathways, leading to the continuous increase in soil pollution in my country. Facts have proven that the soil environment not only affects plant growth and development, as well as the quantity and quality of agricultural products, but also affects human health and safety through the food chain. Soil pollution has become a major environmental issue in my country that urgently needs to be addressed.

[0003] Soil microbial remediation technology utilizes indigenous or artificially domesticated microorganisms with specialized functions to, under suitable environmental conditions, reduce the activity of harmful pollutants in the soil or degrade them into harmless substances through their own metabolism. In situ microbial remediation does not require the contaminated soil to be removed from the site. Instead, nutrients such as nitrogen and phosphorus are directly added to the contaminated soil, along with oxygen, to promote the metabolic activity of indigenous or specialized microorganisms in the soil and degrade pollutants. Existing in situ microbial remediation techniques generally involve turning over the soil and applying a remediation agent to allow it to penetrate. However, this method limits the depth of soil turning over and the penetration time of the remediation agent is too short, resulting in poor remediation results.

[0004] Based on this, the present invention designs an intelligent soil microbial remediation equipment and a remediation method thereof to solve the above problems. Summary of the Invention

5. A soil microbial remediation method, using the intelligent soil microbial remediation equipment according to claim 4, characterized in that: The following methods are included: S1: Connect the driving motor (9) to a power source, thereby driving the moving wheel (11) to rotate, driving the equipment base plate (1) to move to the soil area to be treated, pausing the driving motor (9) from the edge of the soil to be treated, and then connecting the hydraulic pump (3) and the rotating motor (5) to the circuit, the hydraulic pump (3) drives the lifting support shaft (4) to move downward, and drives the drilling shaft (6) to rotate through the rotating motor (5), so that the soil layer is drilled by the drilling drill bit (7); S2: After the drilling is completed, the drilling drill (7) is reset, the hydraulic pump (3) and the rotating motor (5) are suspended, and the driving motor (9) continues to drive the equipment base plate (1) to move forward to expose the drilling position. At this time, the operator holds the magnet ring (27) to remove the material guide cylinder (16) from the limit groove, and then inserts the material guide cylinder (16) into the drill hole; S3: When inserting the material guide cylinder (16) into the drill hole, hold the magnet ring (27) with one hand and vertically insert the material guide cylinder (16) along the drill hole, and hold the fixing ground nail (23) with the other hand. After the material guide cylinder (16) is completely inserted into the drill hole, insert the fixing ground nail (23) into the soil on one side of the drill hole; S4: After the material guide cylinder (16) is inserted into the borehole, the rubber cylinder (28) at the bottom is compressed and deformed under the action of gravity, and the induction bottom plate (30) contacts the bottom of the borehole, so that the power connection column (31) and the power supply battery (29) contact each other, and the electromagnet (19) is connected to the circuit. At this time, a magnetic attraction is generated between the electromagnet (19) and the magnet ring (27), driving the piston (25) to move downward along the material storage cylinder (24), squeezing the microbial repair agent inside the material storage cylinder (24) into the material guide cylinder (16), and then flowing out along the material guide flow channel (17) to the discharge trough (20), and slowly diffusing into the soil layer; S5: The drilling mechanism is driven to move by the equipment base plate (1) to realize continuous drilling and material discharge operations. After the repair time is completed, the material guide cylinder (16) is recovered according to the position of the fixed ground nail (23), and the material guide cylinder (16) is extracted from the drilled hole and the microbial repair agent is added again for recycling.
