The invention discloses a soil remediation system based on fuel gas thermal desorption coupling bioremediation. The soil remediation system is characterized in that a first communicating pipe is arranged on a smoke exhaust pipe, a heating plate is detachably connected with the first communicating pipe, a main pipeline is arranged on a nutrition agent evaporation box, and a plurality of remediation branch pipelines are arranged on a flow divider. According to the invention, high-temperature flue gas exhausted from a heating well is collected through a flue gas collection box and conveyed to a heating plate through a first communication pipe on a flue gas exhaust pipe, a nutrition mixing liquid in a nutrition agent evaporation box is heated and evaporated into steam, the steam is conveyed to a main pipeline, the nutrition steam is conveyed into all remediation branch pipelines through a flow divider on the main pipeline, and nutrient substances are conveyed to native microorganisms in contaminated soil of all repairing wells through air holes, so that the repairing rate of medium-low-degree contaminated areas through microorganism repairing is increased.
Description
technical field [0001] The invention relates to the technical field of soil thermal desorption equipment, in particular to a soil remediation system based on gas thermal desorption coupled with bioremediation. Background technique [0002] Thermal desorption technology refers to the process of heating the polluted medium and the pollutants contained in it to a sufficient temperature through direct or indirect heat exchange, so that the pollutants can be volatilized or separated from the polluted medium. Soil indirect thermal desorption technology is The method of indirect heat exchange between the flue gas produced by the fuel and the soil makes the pollutant components in the soil reach a sufficient temperature to evaporate and separate from the soil medium. Since organic pollutants often have a high boiling point, thermal desorption During the process, the soil needs to be heated to a higher temperature, and a large amount of high-temperature flue gas will be generated aft...
