Description
Technical Field
The invention belongs to the technical field of ecological restoration, and particularly discloses an ecological restoration auxiliary device for a heavy metal region and a using method thereof.
Background
The remediation of the heavy metal contaminated soil is an important step for the remediation of the ecological environment of a heavy metal region, and once the heavy metal content in the soil exceeds the environmental capacity, the soil is not degraded and has small mobility, the removal of the pollution is quite difficult due to the long-term property, the latency, the accumulation and the irreversible transformation of the heavy metal pollution. For the treatment of heavy metal contaminated soil, common physical treatment methods include an electric soil remediation method, a heat treatment method and a soil leaching method; the electric soil remediation method is mainly suitable for heavy metal pollutant treatment, and heavy metals in the soil are brought to two ends of an electrode under the action of an electric field in modes of electroosmosis, electrophoresis and the like, so that the polluted soil is cleaned; the heat treatment method is to heat and raise the temperature of soil so as to volatilize volatile harmful heavy metals from the soil and treat the volatile harmful heavy metals; the soil leaching method is a soil remediation technology in which a certain liquid having a dissolving capacity for contaminants is mixed with soil and rubbed, so that the contaminants are transferred to a liquid phase and a small part of the soil; among the three methods, the soil leaching method is simple and easy to implement, has an obvious remediation effect, and is often used in remediation practices of soil in heavy metal regions.
The soil leaching includes both in-situ and ex-situ soil leaching. In-situ soil leaching generally refers to a process of injecting or permeating flushing liquid into a soil pollution area from an injection well, carrying pollutants to underground water, then pumping the polluted underground water by a pump, and removing the pollutants on the ground. The ectopic chemical leaching technology needs to excavate polluted soil, clean the soil with water or eluent solution, remove pollutants, treat cleaning wastewater or waste liquid containing pollutants, and backfill or transport clean soil to other places for recycling. The soil remediation of heavy metal areas by using a soil leaching method also has certain problems, the leaching effect of the soil by using a surfactant is poor, and the cost is high; secondary pollution is easily caused by leaching with an artificial chelating agent; the inorganic eluting agent is used for eluting, although the cost is low and the effect is quick, the soil structure is easy to damage, so that the nutrient element loss and the soil fertility are low, and the ecological restoration of a heavy metal area is not facilitated.
