Description

Technical Field

[0001] The utility model relates to the technical field of contaminated soil restoration, and more specifically to a contaminated soil leaching device. Background Art

[0002] In modern society, industrialization has developed rapidly. The over-exploitation of soil resources and the unregulated disposal of industrial waste have led to soil pollution problems. Among the methods for remediating contaminated soil, soil washing has the advantages of being less time-consuming and having a wide range of applications, and is a commonly used remediation technology.

[0003] After searching, the utility model patent with the announcement number CN218168196U discloses a contaminated soil elution device, comprising: a elution column, a spraying component is provided at the upper end, a first filter plate is provided at the lower part of the spraying component, a second filter plate is provided at the lower end of the elution column, and a chamber is constructed between the first filter plate and the second filter plate; a drainage port is provided at the bottom of the elution column; an elution liquid supply unit is connected with the spraying component through a transport pipe; the contaminated soil elution device has a simple structure and is easy to operate. The elution liquid is provided to the spraying component of the elution column through the elution liquid supply unit, and the elution liquid is evenly dispersed through the first filter plate and then applied to the contaminated soil in the chamber to mix for contact and reaction, and then filtered through the second filter plate to filter out the waste liquid after the repair treatment, so that in the soil elution process, the elution liquid falls on the contaminated soil in the chamber evenly over a large area for contact, the repair effect is good, and the repair treatment efficiency can be improved. However, the above patents still have the following shortcomings: the contaminated soil needs to be placed in a leaching column for treatment, which is inconvenient for loading and unloading the soil and inconvenient for continuous soil repair. For this reason, we propose a contaminated soil leaching device. Utility Model Content
