The invention relates to a solar in-situ reinforced vapor extracting system for restoring soil organic pollutants. The solar in-situ reinforced vapor extracting system comprises a pipeline of a vapor extracting pipe 4, a water circulating system pipeline buried in organic pollutant soil, a solar heat collecting system 1, a heat insulating water tank 2, a gas purifying system and a soil water replenishing system, wherein the water circulating system pipeline is communicated with the solar heat collecting system 1 on the ground so as to form a solar circulating water heating system, the water circulating system pipeline is communicated with the heat insulating water tank 2 so as to form a heat insulating water tank heat storage circulating water system, and the solar heat collecting system 1 is communicated with the heat insulating water tank 2 so as to form a solar and heat insulating water tank combination circulating water heating system; pumps 12 and 13 and valves 7, 8, 9, 10 and 11 are arranged on pipelines of the solar circulating water heating system, the heat insulating water tank heat storage circulating water system and the solar and heat insulating water tank combination circulating water heating system; and the pipeline of the vapor extracting pipe 4 is communicated with the gas purifying system on the ground. The system utilizes solar reinforced in-situ vapor extraction to restore the soil organic pollutants, is compact, is convenient to operate and saves energy.
