Abstract

The invention relates to a soil leaching quality-improvement restoration device with a tail gas treatment function. The soil leaching quality-improvement restoration device comprises a polluted soil feeding system, a leaching separation system, a solid-liquid separation machine, a precipitate reaction system, a press filter, a rotary heating system, a cyclone separator, a condenser, a screw soil discharging device, a dust removal system, a condensation tower, a pollutant discharging system, a tail gas treatment system and a gas discharging system, wherein the polluted soil feeding system is connected with the leaching separation system, the leaching separation system is respectively connected with the precipitate reaction system and the rotary heating system by virtue of solid-liquid separation machine, the precipitate reaction system is connected with the press filter, the rotary heating system is respectively connected with the screw soil discharging device and the dust removal system by virtue of the cyclone separator, and the dust removal system is respectively connected with the pollutant discharging system and the gas discharging system by virtue of the condensation tower. By adopting the soil leaching quality-improvement restoration device, the soil is restored by virtue of a leaching and thermal desorption technology, heavy metals and volatile and semi-volatile organic pollutants in the soil can be removed.

Description

technical field [0001] The invention belongs to the field of soil remediation in the technical field of environmental engineering, in particular to a soil leaching and quality improvement remediation device with tail gas treatment function. Background technique [0002] Soil is an integral part of ecological environment equipment and the most important and basic comprehensive natural resource for human survival and development. However, with the rapid development of my country's industrialization, irrational mining of mineral resources and their smelting discharge, long-term soil irrigation and sludge application, atmospheric deposition caused by human activities, application of chemical fertilizers and pesticides, etc., the published data It shows that my country's polluted cultivated land is about 150 million mu, accounting for 8.3% of the 1.8 billion mu of cultivated land. How to protect our country's land, remediate soil pollution, establish a virtuous cycle of ecologica...
