Heavy metal contaminated soil mixed remediation device

Abstract

The invention discloses a heavy metal contaminated soil mixed remediation device which comprises a base, a shell, a handle, a soil removing mechanism and a soil remediation mechanism. Moving wheels are arranged below the base, a shell is installed above the base, a handle is installed on the side face of the shell, a soil remediation mechanism is installed at the end, close to the handle, in the shell, a soil removing mechanism is installed at the end, away from the handle, in the shell, and the soil remediation mechanism comprises a feeding box, a guiding barrel and a supporting column. The bottom of the feeding box is fixedly connected with a guiding cylinder, and the left side and the right side of the bottom of the guiding cylinder are fixedly connected with supporting columns. The device has the advantages that the device can work on grounds with different heights, new soil is covered for restoration treatment while surface heavy metal contaminated soil is removed from a to-be-restored land parcel, manual operation is not needed, heavy metal residues are prevented from harming the health of workers, soil can be taken and mixed on site, and the working efficiency is improved. And the soil mixing remediation efficiency is high, the applicability is wide, and secondary pollution to the environment is avoided.

Description

technical field [0001] The invention relates to the technical field of repairing devices, in particular to a mixed repairing device for heavy metal polluted soil. Background technique [0002] Heavy metal pollution is one of the most extensive and most harmful environmental problems in soil pollution today. Heavy metal pollution is different from pollution from other organic compounds. Organic compounds can be purified by nature's own microorganisms to reduce or eliminate the harmfulness. Heavy metals are very harmful. It is difficult to be degraded by microorganisms. The pollution sources of heavy metals in soil mainly come from waste discharges generated by chemical, electroplating and electronics industries. High concentrations of heavy metal elements will produce severe toxicity. The stability has an impact, causing poisoning and even death of animals and plants, so it is necessary to remediate the contaminated soil. [0003] Existing soil remediation devices can only w...

AI Technical Summary

Problems solved by technology

[0003] Existing soil remediation devices can only work on flat ground when in use, and remove heavy metal-contaminated soil on the surface of the land to be repaired, but the equipment can only be treated on the soil surface, and the soil remediation device needs to be manually disassembled after use Cleaning, the operation process is complicated and cumbersome, and the heavy metal residues are likely to endanger the health of the staff. The restoration device cannot carry out soil extraction and mixing on the spot. There are great limitations in the efficiency of manual direct mixing of contaminated soil. The cost is high, and the high cost of chemical repair technology may cause secondary pollution to the environment, which is not conducive to environmental protection
