An ecological restoration device for polluted water bodies in a watershed

Abstract

This utility model relates to the field of ecological restoration technology and discloses an ecological restoration device for polluted water bodies in a watershed. It includes uprights, with a vertical rod fixedly connected to the top of two adjacent uprights, and a horizontal rod fixedly connected to the top of two adjacent vertical rods. A planting trough is fixedly connected to the top of the uprights, and a top cover is fitted onto the top of the planting trough. Multiple water passage holes are provided on the outer walls of both the planting trough and the top cover. Multiple biofilm carriers are fixedly connected to the bottom surface of the planting trough, and an adsorption box is fixedly connected to the bottom surface of the uprights. Multiple support rods are fixedly connected to the outer wall of the upper vertical rods, and a solar panel is fixedly connected to the top of the support rods. In this utility model, nitrogen and phosphorus nutrients in the water are absorbed by the plant roots in the planting trough, the biofilm carriers provide a surface for microorganisms to attach and grow, and the adsorption box is filled with activated carbon and adsorption materials to adsorb and remove pollutants from the water, further purifying the water quality.
