Description

TECHNICAL FIELD

[0001] The utility model relates to the field of soil pollution prevention and control, especially relates to a hydraulic ring soil pollution remediation device. BACKGROUND

[0002] Soil remediation is a process of applying physical, chemical and biological methods to reduce the concentration of soil pollutants and transform them into harmless substances to restore the normal function of soil, promote vegetation recovery and biodiversity, maintain the ecological system, reduce the transmission of pollutants in the food chain, improve the quality and yield of agricultural products, reduce the exposure of pollutants and prevent the migration of pollutants to water bodies. Its application fields cover industrial contaminated sites, mine and tailings pollution control, agricultural soil pollution remediation and oil-contaminated soil remediation, which have important significance and wide application value in many aspects.

[0003] Early soil remediation often uses excavation and landfill method in industrial contaminated sites, that is, contaminated soil is excavated and filled in a specific site. For slightly contaminated soil, deep plowing is carried out to turn the contaminated layer to the lower layer. For heavily contaminated soil, soil replacement method is used to directly replace new soil. Excavation and landfill only transfer pollution rather than truly treat it. The landfill site is difficult to choose and the subsequent management is complex. Deep plowing is easy to cause the diffusion of pollutants in the deep soil, which may cause long-term hidden dangers. The existing soil electrodialysis method causes directional movement of ions and water molecules in pore water when a direct current field is applied on the surface of soil particles with negative charge. Cations move to the cathode and anions move to the anode. At the same time, electroosmotic flow is generated to make pollutants migrate and enrich near the electrode for extraction and treatment, which fundamentally reduces the content of pollutants in soil and avoids the problem of pollution transfer. However, there is still a problem that the electroosmotic flow is difficult to form due to the influence of soil properties such as texture, porosity and water content on electrodialysis remediation, which affects the migration of pollutants.
