In-situ full-automatic contaminated soil remediation device

Abstract

Belonging to the technical field of soil remediation, the invention in particular relates to an in-situ full-automatic contaminated soil remediation device. Disposed on a delivery vehicle, the device comprises a soil metal ion chelating agent and acid-base neutralizing agent injection instrument, a metal ion electrokinetic remediation instrument, a soil remediation microbial spray instrument, a rotary tillage and rotovation instrument, and a microcomputer control system. Specifically, the soil metal ion chelating agent and acid-base neutralizing agent injection instrument, the soil remediation microbial spray instrument, the metal ion electrokinetic remediation instrument and in electric connection with the microcomputer control system. The soil metal ion chelating agent and acid-base neutralizing agent injection instrument and the soil remediation microbial spray instrument respectively perform chemical chelation remediation and microbial in-situ remediation on the contaminated soil. The metal ion electrokinetic remediation instrument performs electrokinetic remediation on the contaminated soil. The rotary tillage and rotovation instrument is connected to a power unit of the delivery vehicle through a rotary tillage and rotovation transmission unit. And the rotary tillage and rotovation instrument performs aeration oxidation remediation on the contaminated soil. The in-situ full-automatic contaminated soil remediation device provided by the invention has the characteristics of high degree of automation, high efficiency, low energy consumption, and environmental protection, etc.

Description

technical field [0001] The invention belongs to the technical field of soil remediation, in particular to an in-situ automatic contaminated soil remediation device. Background technique [0002] With the rapid development of industry and agriculture, the content of heavy metals in soil has increased year by year, and the pollution caused by it has become increasingly serious. Prevention and control of soil pollution and protection of limited soil resources have become prominent global issues. Heavy metal pollution in soil is concealed, long-term and irreversible. The pollutants stay in the soil for a long time and cannot be degraded by plants or microorganisms. The food chain endangers human life and health. [0003] At present, the soil in many parts of the world is seriously polluted by heavy metals and organic matter, and the polluted arable land area in China already accounts for 1 / 5 of the total arable land area. Soil pollution has brought a series of serious problem...

Problems solved by technology

However, it is difficult for these devices to ensure that the restoration can be completed quickly and effectively, and these restoration methods are relatively isolated, and cannot well solve the difficulties of complex and in-situ restoration of existing polluted soil.
