Problems solved by technology

The traditional barrage spans the river, blocking the original normal river runoff. The water level in the upstream of the barrage rises, resulting in a still water area, and the downstream flow velocity decreases, the water volume decreases, and even the downstream flow will stop; (2) Water quality deteriorates
Due to the decrease of water flow velocity in the upstream and downstream of the barrage, the oxygen content of the water body will decrease, and the nutrients and pollutants in the water body will not be effectively diluted and diffused, which will easily cause eutrophication of the water body in the upstream of the barrage and dam, and the water quality will deteriorate; (3 ) Biological migration pathway loss
Due to changes in hydrodynamic conditions, the habitats, growth, and reproduction of organisms in the upstream and downstream of the barrage have changed, especially blocking the free migration and migration of organisms in the upstream and downstream. Unable to survive, resulting in the reduction of biodiversity, and even the extinction of some rare species
In addition, the barrages and dams are composed of simple cement stones or earth stones, which do not have the effect of beautifying the landscape.

Abstract

The invention discloses an environment-friendly barrage. The environment-friendly barrage comprises a barrage body, a green purifier, a gate chamber and a control system, wherein the green purifier is arranged above the barrage body, and a water flow passage is formed between the green purifier and the top part of the barrage body; the gate chamber is arranged beside a river bank and is used for containing the green purifier; the control system is connected with the green purifier, and the green purifier is controlled to rotate between the gate chamber and the top part of the barrage body by the control system. The invention also discloses a water body purification method. The water body purification method comprises the following steps of moving the green purifier into the gate chamber when a water level exceeds a designed water level; putting the green purifier at the top part of the barrage when the water level does not exceed the designed water level, and purifying a river through the green purifier. According to the environment-friendly barrage and the water body purification method, disclosed by the invention, the negative effects on hydrodynamic conditions, water body environment and biological migration of an existing barrage are overcome, and the landscape visual effect of the environment-friendly barrage is enhanced.

Description

technical field [0001] The invention belongs to the technical field of barrages and dams, and in particular relates to an eco-friendly barrage and a method for purifying water using the barrages and dams. technical background [0002] There are many barrages and dams in our country, especially in the rivers in hilly areas, people have built a large number of barrages and dams for irrigation and living needs. These traditional barrages are water-retaining structures across the river, which only consider the functions of flood control, water storage, and irrigation, without considering the ecological and environmental requirements of the river. These barrages have certain negative impacts on the ecological environment of rivers, which are mainly manifested in the following aspects: (1) Changes in hydrodynamic conditions. The traditional barrage spans the river, blocking the original normal river runoff. The upstream water level of the barrage rises, creating a still water zon...
