A dam body device for urban artificial river management

Abstract

The invention provides a dam body device for harnessing urban artificial rivers. It includes: the first dam body, which is extended along the width direction of the urban artificial river; the lower part of the first dam body has a first drainage channel; the side of the first dam body facing the downstream of the urban artificial river is a slope surface, and the slope surface A plurality of first bumps are arranged on the top; the first blocking device is configured to conduct or cut off the first drainage channel; the aquatic plant planting area is arranged downstream of the first dam body and is configured to plant aquatic plants; and blocking facilities , arranged downstream of the aquatic plant planting area, and the arresting facility has at least one arresting unit, and each arresting unit has a first fish wire mesh, an activated carbon fiber filter cloth, a chitosan fiber filter cloth and a second fish wire mesh. The dam body device has a simple structure, can isolate algae floating objects such as cyanobacteria in the water body, intercept and remove some organic matter and heavy metals, and has 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 ...
