Experimental device for studying migration of heavy metals in water

The utility model relates to an experimental device for studying heavy metal migration in water, which comprises a downstream side water reservoir, an upstream side water reservoir, experimental water tanks, water conveying pipes and an electric control device, the experimental water tanks and the water conveying pipes are connected between the downstream side water reservoir and the upstream side water reservoir, and the water conveying pipes are parallel to the experimental water tanks which are arranged side by side; a water inlet of the experimental water tank is communicated with the upstream side reservoir, and a water outlet is communicated with the downstream side reservoir; a water inlet of the water delivery pipe is communicated with the downstream reservoir through a water pump, and a water outlet is communicated with the upstream reservoir; a groove is formed in the bottom of the experimental water tank and is used for placing a sediment sample; stop blocks are arranged on any one surface or sever
