Simulation device and method for studying the influence of wetland plant litter decomposition on water quality

Simulation device for studying the influence of decomposition of plant litter on water quality, comprising a distributing reservoir, a planting pool and a discharge bay, and the distributing reservoir, the planting pool, and the discharge bay are connected successively through a first-level pipeline;

• the distributing reservoir is used for supplying water to the planting pool;
• the discharge bay is used for collecting wastewater discharged from the planting pool;
• the planting pool comprises at least one planting unit;
• the planting unit is a container-like structure and used to hold a planting substrate and plant the plant on the planting substrate;
• according to a direction of water flow, the first-level pipeline leading from the distributing reservoir to the planting pool is a first-level inlet pipeline, the pipeline leading from the planting pool to the discharge bay is a first-level outlet pipeline;
• each planting unit has a water inlet and a water outlet, and the water outlet of each planting unit is respectively connected to the first-level outlet pipeline through a second level outlet pipeline, and the water inlet of each planting unit is connected to the first-level inlet pipeline through a second level inlet pipeline, so that the respective planting units are arranged in the parallel arrangement.
