Dam body device for treatment of urban artificial watercourse

Abstract

The invention provides a dam body device for treatment of an urban artificial watercourse. The dam body device comprises a first dam body, a first plugging device, an aquatic plant planting zone and a blocking device, wherein the first dam body extends in the width direction of the urban artificial watercourse; the lower part of the first dam body is provided with a first drainage channel; the side surface, facing the downstream part of the urban artificial watercourse, of the first dam body is a slope surface; a plurality of first salient points are arranged on the slope surface; the first plugging device is arranged to conduct or cut off the first drainage channel; the aquatic plant planting zone is arranged at the downstream part of the first dam body; the aquatic plant planting zone is arranged for planting aquatic plants; the blocking device is arranged at the downstream part of the aquatic plant planting zone, and is provided with at least one blocking unit; and the blocking units are provided with first fish screens, activated carbon fiber filter cloth, chitosan fiber filter cloth and second fish screens which are sequentially arranged in the water flowing direction. The dam body device is simple in structure, can isolate algae floating objects like blue-green algae in a water body, can block and remove parts of organic substances and heavy metals, and has an excellent treatment effect.

Description

technical field [0001] The invention relates to a pollution blocking device, in particular to a dam body device used for urban artificial river management. Background technique [0002] With the rapid development of modern social economy, urban residents put forward higher requirements for urban living environment. As an indispensable part of urban environmental ecology, urban artificial rivers not only provide leisure, entertainment, landscape and ecological functions, but also play an important role in urban flood control and waterlogging prevention. Due to man-made structures and poor water circulation, the self-purification ability of urban artificial rivers is obviously inferior to that of natural rivers. If the long-term shortage of rainwater cannot maintain the virtuous cycle of the artificial river, coupled with the discharge of domestic sewage from the surrounding residents, it will further lead to serious eutrophication of the water body, the growth of blue-green ...
