Abstract

The invention discloses a soil repairing system and a soil repairing method. The soil repairing system comprises a preheating device, a heating device, a heat recycling device and a heat transmission device. The preheating device is used for preheating polluted soil. The heating device is connected with the preheating device and used for heating the preheated and polluted soil and separating pollutant in the soil. The heat recycling device is connected with the heating device and used for recycling heat of the polluted soil heated by the heating device. Further, the soil repairing system comprises a heat transmission device communicated with the preheating device through the heat transmission device to enable the heat recycling device to serve as a heat source of the preheating device. The soil repairing system and the soil repairing method effectively reduce cost of heat repairing of the polluted soil, and are favorable for quickly cooling the soil and apt to quick backfill of the soil.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to a soil restoration system and a soil restoration method. Background technique [0002] With the development of society and the gradual intensification of industrialization, industrial polluted sites have gradually increased. In order to ensure the ecological environment and human health, the remediation of contaminated soil in polluted sites has become an urgent problem to be solved. [0003] Currently, soil remediation techniques include incineration, thermal desorption, soil leaching, ex-situ immobilization / stabilization techniques, and biodegradation. Among them, most of our country uses incineration technology when dealing with hazardous waste and polluted soil. However, incineration directly destroys the nature of the soil itself, making the soil lose its original function, and the energy consumption is high, which is prone to secondary pollution.
