Remediation device for organic contaminated soil

Abstract

The invention discloses a remediation device for organic contaminated soil. The remediation device comprises a soil treatment bin, a gas purification chamber and a conveying belt base. A plurality of metal square pipes are arranged in the soil treatment bin and are arranged in a multi-layer array manner; each metal square tube can periodically rotate and is internally provided with an electromagnetic induction coil, and electrodes connected with any two adjacent layers of metal square tubes are opposite; a magnetic field area and a catalyst filling area are arranged in the gas purification chamber. In this way, in the layer-by-layer falling process of the contaminated soil, the contaminated soil is subjected to multiple times of rolling, heating, electrolytic degradation, organic pollutant desorption, organic matter polarization or polar plate collision electrification treatment; after tail gas enters the magnetic field area, uncharged organic gas collides with charged particles and reacts with the charged particles, and then the uncharged organic gas is further oxidized by catalytically activated ozone active substances in the filling area to be thoroughly oxidized. According to the method, deep remediation of the organic contaminated soil can be achieved at low cost and high efficiency, tail gas is purified before emission, and the method is environmentally friendly.

Description

technical field [0001] The invention relates to the field of environmental engineering, in particular to a remediation device for organic polluted soil. Background technique [0002] At present, soil pollution has become a major environmental problem affecting human survival and sustainable development. Toxic and harmful pollutants accumulate continuously in the soil, and when the harmful substances accumulate to a certain level, they may seriously damage the entire ecosystem. [0003] Organic pollutants are important pollutants that endanger the safety of the soil environment, and at the same time have huge potential safety hazards to agricultural production and human health. POPs are also one of the main culprits of soil pollution. Pesticide pesticides such as chlordane, mirex, hexahexahexanol, and DDT, which were mass-produced and widely used, can cause soil pollution during production and use. Although they have been banned for many years, there are still a lot of resi...
