Laboratory simulation device for groundwater pollution remediation and usage method of laboratory simulation device

An embodiment of the invention provides a laboratory simulation device for groundwater pollution remediation and a usage method of the laboratory simulation device. The device comprises a simulation aquifer unit, a water pumping and distributing unit, a remediation unit, an air stripping unit and a monitoring unit, wherein water is delivered to a simulation aquifer through a first peristaltic pump by a water storage barrel; a water pumping well and a water pumping pipe are communicated with the simulation aquifer and the outside, a sieve pipe is located below the water level of the simulation aquifer, and a water intake port of the water pumping pipe is located at the lower part of the sieve pipe; a second peristaltic pump is communicated with the water pumping pipe and a water guide pipe, and the other end of the water guide pipe is connected with a T-shaped water distributing pipe; the bottom of a seepage zone is communicated with the simulation aquifer; a water flow flows in filler layers of the seepage zone and a reaction zone in an S shape; multiple air guide pipes capable of being closed are distributed in an overlaying soil layer; an aeration fan is connected with one end of an air delivery pipe, and the other end of the air delivery pipe extends below the water level of a water layer of the water pumping well; multiple air pumping wells are communicated with the simulation aquifer and the outside and connected with an air pump; the monitoring unit comprises multiple sampling pipes which are located at the simulation aquifer, the reaction zone and the seepage zone respectively.
