Device and method for distillation treatment of soil pollutants

Abstract

The invention discloses a device and a method for carrying out distillation treatment on soil pollutants, wherein the device comprises a steam high-pressure boiler, a main steel tube, branch steel tubes, a water injecting steel tube, a condensing tube, a concrete cover plate, a geomembrane and a collecting device, wherein the main steel tube communicates with the steam high-pressure boiler; the main steel tube communicates with the water injecting steel tube; the geomembrane is attached to the surface of the inner part of a pit; the opening of the pit is sealed with the concrete cover plate; one end of each branch steel tube is tapped into the sealed space; the other ends of the branch steel tubes extend in a length direction to penetrate through the concrete cover plate, and communicate with the main steel tube; one end of the condensing tube communicates with the inner part of the sealed space; and the other end of the condensing tube communicates with the collecting device. The device and the method solve the problem that pollutants in soil are effectively and completely eliminated due to the fact that novel pollutants are generated when a chemical treatment method, namely a normal method for treating the soil pollutants at present, is utilized to treat the polluted soil.

Description

Technical field

[0001] The invention relates to a soil pollutant treatment device and method, in particular to a device and method for distillation treatment of soil pollutants. Background technique

[0002] With the rapid development of industrial and agricultural production, the natural environment for human existence is increasingly severely affected by various adverse factors. A large amount of waste water, waste gas and solid waste are discharged to the environment, causing environmental pollution, including soil pollution. Exogenous toxic and harmful pesticides, petroleum, heavy metals, and acidic substances have disrupted the inherent dynamic balance of substances in the soil and the ecosystem. As an invisible pollution, soil pollution has attracted more and more attention. Common soil pollutants include aromatic hydrocarbons, benzene, benzopyrene, naphthalene, dibenzanthracene, benzanthracene, benzofluoranthene and indenopyrene, etc. At present, the common method to trea...
