Heavy metal contaminated soil remediation system

Abstract

The invention discloses a heavy metal contaminated soil remediation system, which comprises a remediation cylinder, wherein a spiral feeder used for conveying soil is installed in the remediation cylinder, and the outer side of the spiral feeder is sleeved with a screening filtrate mechanism which is connected with the inner wall of the remediation cylinder and used for filtering the soil. By means of a sieve mesh ring set and a filtering agent pipe, the system achieves multiple times of filtration on the remediated soil, so that extraction efficiency of the remediation agent is higher, and the soil cannot flow away along with remediation agent. When the soil remediation system is implemented, the spiral feeder is directly driven to feed the remediated soil into a soil storage ring, in theconveying process of the soil, the soil can be preliminarily filtered through the sieve mesh ring set, then the soil entering the soil storage ring can be filtered step by step through the filteringagent pipe, so that the soil is finally located in the soil storage ring, the remediation agent is located in the remediation cylinder, and subsequent remediation agent extraction and treatment operation is facilitated.

Description

Technical field[0001]The invention relates to the technical field of soil remediation, in particular to a heavy metal contaminated soil remediation system.Background technique[0002]Heavy metals mainly refer to heavy elements with significant biological toxicity. Air, soil, and even drinking water contain heavy metals, such as free radicals that cause aging, particles that are harmful to the skin, dust in the air, car exhaust, etc., and even tap water Both bring heavy metals to the skin. After heavy metals accumulate, they are quite harmful to the human body. Therefore, it is necessary to repair the soil. Soil repair is a technical measure to restore the normal function of the contaminated soil. In the soil remediation industry, there are more than one hundred kinds of soil remediation technologies, and there are also more than ten commonly used technologies, which can be roughly divided into three methods: physical, chemical and biological.[0003]Remediation of heavy metal contaminat...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a heavy metal contaminated soil remediation system to solve the problem that it is difficult to extract the remediation agent in the soil after fully mixing the remediation agent in the prior art, and at the same time, when the remediation agent is discharged, a large amount of soil will be Technical issues that drained along with the Restoration Potion
