River ecological restoration device

Abstract

The invention discloses a river ecology restoration device in the technical field of river ecology, a collecting mechanism comprises a mounting plate, one end of the mounting plate is fixedly mounted on the outer surface of a water inlet cylinder, a water inlet is fixedly mounted at the top end in the water inlet cylinder, and a collecting box for collecting aquatic plants is fixedly connected to the lower end of the water inlet; the interior of the collecting box is rotatably connected with a rotary drum, the outer surface of the rotary drum is fixedly connected with a plurality of baffles distributed in a circumferential array, and a material pushing plate is arranged between every two adjacent baffles, so that duckweed collected on a river can be effectively collected, and the collecting mechanism can well separate water from duckweed; the duckweed collecting device can effectively collect duckweed collected on a river, the collecting mechanism can well separate water from the duckweed, the volume of the water and the duckweed together is reduced, the volume of the water and the duckweed together in subsequent grinding and smashing treatment is facilitated, and subsequent grinding and smashing treatment is facilitated.

Description

technical field [0001] The invention relates to the technical field of river ecology, in particular to a river ecology restoration device. Background technique [0002] With the rapid development of the economy, a large amount of industrial wastewater, domestic sewage and plant nutrients in farmland runoff are discharged into the rivers around the city, resulting in excessive nitrogen, phosphorus and other plant nutrients in the river water, and aquatic organisms, especially algae will multiply. , the amount of dissolved oxygen in the water drops, fish and other organisms die in large numbers, and the ecological balance is destroyed. Some filamentous algae floating on the water surface such as duckweed have caused serious river pollution to the river. The isolation from the air will accelerate the deterioration of the water quality and intensify the eutrophication of the water, especially during the high incidence period of duckweed, which will breed a large number of duckwe...

Problems solved by technology

[0002] With the rapid development of the economy, a large amount of industrial wastewater, domestic sewage and plant nutrients in farmland runoff are discharged into the rivers around the city, resulting in excessive nitrogen, phosphorus and other plant nutrients in the river water, and aquatic organisms, especially algae will multiply. , the amount of dissolved oxygen in the water drops, fish and other organisms die in large numbers, and the ecological balance is destroyed. Some filamentous algae floating on the water surface such as duckweed have caused serious river pollution to the river. The isolation from the air will accelerate the deterioration of the water quality and intensify the eutrophication of the water, especially during the high incidence period of duckweed, which will breed a large number of duckweed. If it is not salvaged and treated, the area of ​​the water surface will also decrease. The concentration of dissolved oxygen in the water decreases, the water area becomes more eutrophic, and eventually accelerates the aging of the water body, causing serious ecological damage to the river
