Culture device and method for simulating suspended matter-water interface N2O discharge

The invention discloses a culture device for simulating suspended matter-water interface N2O emission and a method thereof, and relates to the technical field of environmental engineering. The device comprises a motor mounted on a fixed column and a magnetic rotating device connected with the motor, according to the magnetic rotating device, a radial magnetic coupler is installed between a driving shaft and a driven shaft, and magnetic torque is generated to drive the driven shaft to rotate. According to the culture device, a sealing cover is arranged at the top of a culture column, a sealing ring is arranged between the sealing cover and the culture column, a water sampling pipe and a gas sampling pipe are arranged on the sealing cover, and three-way valves in sealed connection are arranged above the water sampling pipe and the gas sampling pipe. The bottom of the culture column is provided with a fixing groove and is in threaded connection with the bottom plate fixing groove. The monitoring device is used f
