Abstract
The invention discloses an integrated type restoring method for soil contaminated by organic matter. Large-size lump soil contaminated by organic matter firstly passes through a soil crusher, is cut and smashed into loose small-size particular soil and then enters an integrated type soil restoring device to be restored, and the restored soil enters a soil recycling box. By means of the method, sealed and integrated treatment and recirculation of the soil are achieved. The removing rate of organic pollutants in the soil is higher than 99%, and the method is especially effective for removing organic matter difficult to volatilize.
Description
Technical field
