Technical Field

The present invention relates to the field of soil remediation, and in particular to a heavy metal soil remediation agent delivery device and a use method thereof.

Background Art

In the electroplating industry, various forms of copper and nickel are often used and discharged by enterprises at the same time. Therefore, there are a large number of copper-nickel composite pollution sites. Chemical leaching agents have certain selectivity and specificity for heavy metals in the soil. Therefore, choosing different leaching agents for different heavy metal excessive soils can achieve the purpose of using lower concentration leaching agents to obtain better results. Chemical leaching remediation technology is a technology that uses aqueous solutions of some extraction/leaching agents to separate or desorb pollutants from soil particles into extraction/leaching solutions through chemical and physical methods. This technology is considered to be the fastest and most effective of all current heavy metal contaminated soil remediation technologies. The method is used. Due to the high population density and the eagerness to develop polluted sites in cities, the eluting agent has a very good effect on the restoration of soil copper and nickel, and it also has a certain removal effect on other heavy metals. It is particularly suitable for the restoration of contaminated soil with serious excess copper and nickel. It is particularly suitable for the restoration of heavy metal contaminated sites in cities. The existing restoration agent delivery device is too single. The restoration agent is directly sprayed on the soil surface and penetrated to the bottom through natural infiltration. However, the penetration process is slow, and the contaminated soil with serious surface pollution is easy to agglomerate and the mixing efficiency with the restoration agent is low, making it difficult for the restoration agent to penetrate to the bottom of the soil, greatly affecting the subsequent leaching restoration effect of the soil.
