Simulation system for monitoring and analyzing dynamic releasing of pollutants in soil filling materials under leaching state

The invention discloses a simulation system for monitoring and analyzing the dynamic releasing of pollutants in soil filling materials under a leaching state. The simulation system consists of eight subsystems, including a sample container external subsystem, a sample container internal subsystem, a high-pressure air supply subsystem, a leaching liquid pH (Potential of Hydrogen) value regulation and control subsystem, a water and air feeding pipeline subsystem, a sensor circuit subsystem, a computer control terminal subsystem and a leaching liquid organic matter separation subsystem, wherein amonitoring and analysis system is characterized in that the high-pressure air supply subsystem and the leaching liquid pH value regulation and control subsystem provide certain pressure gas and leaching liquid with a certain pH value for the sample container internal subsystem through the water and air feeding pipeline subsystem; pressure in the sample container internal subsystem, heavy metal pollutant concentration in
