The invention relates to a volatile contaminated soil and groundwater restoration system. The volatile contaminated soil and groundwater restoration system comprises a soil excavating and crushing system, a soil heating and oscillating system, a moveable soil transportation belt conveyor, a volatile exhaust gas absorption and adsorption system, a wastewater aerobic treatment tank and a wastewater sedimentation tank, wherein the soil heating and oscillating system is of a slope-type structure; the volatile exhaust gas absorption and adsorption system sequentially comprises a volatile exhaust gas oxidation absorption zone, a defogger, an activated carbon adsorption zone and an exhaust fan from bottom to top, the volatile exhaust gas oxidation absorption zone is communicated with the wastewater aerobic treatment tank, an underground contaminated wastewater inlet pipe is arranged at the upper part of the wastewater aerobic treatment tank and an aeration device is arranged at the bottom of the wastewater aerobic treatment tank; the water inlet of the wastewater sedimentation tank is communicated with the water outlet of the wastewater aerobic treatment tank and an overflow weir and a water outlet pipe are arranged at the upper part of the wastewater sedimentation tank; the water outlet pipe of the wastewater sedimentation tank is connected with a treated water circulation pump; and a sludge backflow system is arranged between the wastewater sedimentation tank and the wastewater aerobic treatment tank.
Description
technical field [0001] The invention relates to the technical field of restoration and treatment of polluted soil and groundwater, in particular to a restoration system for volatile polluted soil and groundwater. Background technique [0002] The production process of enterprises often causes serious pollution to the soil. The content of volatile substances in these heavily polluted sites is very high, and most of these pollutants are hydrophobic organic substances, which have low solubility in the water phase and can stay in the environment for a long time. In the soil environment, it not only destroys the structure and function of the soil, has a serious impact on the physical and chemical properties of the soil, but also becomes a long-term pollution source of groundwater. [0003] At present, the treatment of volatile polluted soil mostly adopts digging the soil away from the site for incineration, landfill, water flushing and other treatment, but there are problems such...
