Organic matter soil restoration device

Abstract

The invention discloses an organic matter soil restoration device. The device is characterized by comprising a blower, a soil restoration box, a membrane separation system, a vacuum pump, a condenser and an organic matter collection tank, wherein a soil feed opening is formed in the upper part of the soil restoration box; a soil discharge opening is formed in the side face of the soil restoration box; the soil feed opening is connected with a soil breaking box; the soil discharge opening is connected with a soil cooling box; the soil cooling box is externally provided with a discharge device. The device has the benefits that the device can achieve continuous feeding, has high polluted soil treatment capacity, adopts a direct heating manner, has high heat desorption efficiency, employs the membrane separation system to treat exhaust gas and does not generate secondary pollution.

Description

technical field [0001] The invention relates to a soil remediation device, in particular to an organic soil remediation device. Background technique [0002] At present, with the adjustment of industrial structure and the in-depth implementation of the "Stockholm Convention on Persistent Organic Pollutants (POPs)", a large number of high-polluting enterprises such as pesticide factories, steel factories and chemical factories, especially POPs production and use enterprises They will be gradually shut down and switched to production or relocated. From 2001 to 2007, 86,000 enterprises across the country have stopped production or relocated, resulting in a large amount of high-pollution risk soil. The danger of soil pollution is that after some organic matter pollutes the soil, it will further pollute the air and water around the soil, while some organic matter or heavy metal pollution will pass through the food chain and have adverse effects on the human body. The acceleratio...

AI Technical Summary

Problems solved by technology

However, the gas phase extraction technology has a long running time and cannot meet the needs of undeveloped industrial polluted sites in the city; thermal desorption costs are high and cannot be used to treat large quantities of polluted soil; incineration and landfill technologies have a high risk of secondary pollution. High cost and limited throughput

Therefore, the traditional soil remediation technology is difficult to meet the changing market demand

[0004] Traditional soil remediation technology, when remediating soil contaminated by organic matter, does not deal with the organic matter gas from thermal desorption, which easily produces secondary pollution
