Abstract
The invention discloses a soil restoration system which comprises a pollutant dissolution sub system and an soil drying sub system; the pollutant dissolution sub system comprises an agent storage tank, a mixing tank and a stirring device; the soil drying sub system comprises a vacuum dehydrating belt conveyor, a gas-liquid separator, a vacuum pump, a flushing device and a wastewater collecting treatment device; and a material mixture outlet of the mixing tank is connected with a material conveying tube for conveying a material mixture in the mixing tank onto the filter layer. According to the soil restoration system disclosed by the invention, the pollutant dissolution system realizes agent-adding, stirring and mixing, namely a pollutant dissolution function, and the soil drying system realizes a dehydrating function, a solvent removal function and an soil backfilling function. After being added into the pollutant dissolution system, polluted soil stays certain time under a stirring condition, so that sufficient contact between soil and the solvent is guaranteed. After the pollutant is dissolved out, a soil leacheate mixture in the dissolution system is conveyed into a soil drying backfilling system, so that water and solvent are removed; and then, cleaned soil is backfilled into a field through a transport unit, so that the restoration task is accomplished.
