The invention relates to the technical field of environment, and particularly discloses a
sediment-water interface substance migration and transformation
simulation device and a use method. The device mainly comprises four parts: a columnar
simulation container, a plurality of collection holes, an interface disturbance device, a heating device and an
aeration device, the columnar
simulation container is provided with a lightproof outer
coating, the collection holes are uniformly distributed on the columnar simulation container except one collection hole is additionally arranged at the interface, and each collection hole can collect corresponding overlying water. The columnar simulation container is used for containing
sediment and overlying water, the outer covering layer can simulate the dark environment of the
sediment, and the multiple collection holes are used for obtaining an interface and a nearby overlying
water sample in a layered mode. The device is reasonable in design and convenient to use, migration and transformation of the nutritive salt on the sediment-water interface under different environmental conditions can be accurately simulated, the migration and
diffusion flux of the nutritive salt on the interface can be calculated, and the device has good application prospects in the technical field of the environment.
