Embodiment Construction

[0026] use Figure 1-Figure 3 A remediation method for volatile polluted soil of the present invention is described as follows.

[0027] like Figure 1-Figure 3 , a method for repairing volatile contaminated soil according to the present invention, the method comprises the steps of:

[0028] S1: Remove impurities such as bricks and stones in volatile polluted soil;

[0029] S2: Put the soil that has been cleaned of impurities in S1 into the volatile contaminated soil remediation device from the feed port, and at the same time start the motor, the motor drives the first rotating shaft and the second rotating shaft to rotate, and the second rotating shaft drives the telescopic mechanism below to rotate , the stirring blade stirs the volatile contaminated soil along with the rotating shaft. When the telescopic mechanism is stretched, the air outside the cylinder is sucked into the inner cavity of the telescopic mechanism, and the electric heating wire is heated and discharged i...

Abstract

The invention relates to the technical field of polluted soil restoration and treatment, particularly to a volatile polluted soil repairing method. The volatile polluted soil repairing method comprises the following steps of picking off impurities in volatile polluted soil such as bricks and stone; feeding the impurity-cleaned soil into a volatile polluted soil repairing device via a feeding port,and meanwhile, starting a motor to drive a first rotating shaft and a second rotating shaft to rotate so that the second rotating shaft drives an extending mechanism beneath to rotate, mixing bladescan mix the volatile polluted soil along with the rotating shafts, the extending mechanism extends to absorb air outside a barrel into the inner cavity of the extending mechanism, and then the air isheated by heating wires and discharged into the soil to take out volatile gas. By preprocessing the polluted soil, the volatile polluted soil repairing method can ensure protection over parts inside the volatile polluted soil repairing device; the volatile polluted soil repairing device is simple in structure, convenient to operate, low in manufacturing cost and high in soil repairing efficiency.

Description

technical field [0001] The invention relates to the technical field of remediation and treatment of polluted soil, in particular to a remediation method for volatile polluted soil. Background technique [0002] Volatile organic pollutants are often expressed as VOCs. According to the definition of the World Health Organization, they refer to compounds with a boiling point of 50°C-250°C. The saturated vapor pressure at room temperature exceeds 133.32Pa, and they exist in the air in the form of vapor at room temperature. Organic matter mainly includes alkanes, aromatics, olefins and other organic compounds. Volatile organic pollutants in the soil are easy to enter into the atmosphere and water bodies under the action of wind and water, causing other secondary ecological problems such as air pollution, water pollution, and ecosystem degradation. They can also be absorbed by plants and the food chain. The accumulation of these substances will endanger human health, such as bein...
