Systems and methods for controlling river silt deposition

Abstract

The invention provides a system for controlling silt deposition in a river channel. The system comprises an acceleration section and a deposition section which are located in the river channel, wherein a river channel width D1 of the acceleration section is smaller than a river channel width D2 of the deposition section; a deposition tank is arranged in the deposition section; a slit collecting and dredging device is arranged in the deposition tank. The invention also provides a method for controlling silt deposition in the river channel. The system and the method follow the natural condition and achieve directional orderly flowing of water; the advantage of the tide power is fully utilized; the hydraulic condition of the existing river channel is changed by arranging landscape ecological partition walls under the condition that the scale and the using function of the river channel are not changed; the water can directionally, rapidly, slowly and orderly flow, so that the silt deposition in the river channel is controlled, the water resource is scientifically utilized, and the water environment is completely improved.

Description

technical field [0001] The invention relates to the field of river channel pollution control, in particular to a system and method for controlling river channel silt deposition. Background technique [0002] Black and smelly rivers have a huge impact on water security, investment environment, and people's lives. The causes of black and smelly urban rivers are complex. In some cities, once sewage interception and management, surface pollution control, and river dredging have been implemented, the river water will soon clear up. The river water turned black and stinks again. The reason is that the river is silted up. For this reason, the entire river has to be dredged, once every few years, which affects a wide range of areas, especially in commercial areas and residential areas. It is difficult to dredge the river, and the odor generated during dredging and silt transportation will affect the surrounding environment. Both are big. [0003] The siltation of urban river cou...

AI Technical Summary

Problems solved by technology

[0007] 2. Siltation produces black odor, which seriously affects the water quality of the river and affects the production and life of the people;

[0008] 3. Regular dredging has a wide range, a large amount of dredging, and a wide range of influence

River courses have a huge impact on water security, investment environment, and people's lives; if these silts are not treated, the water quality of the river course will not be guaranteed, the water ecology will not be restored, water security will not be guaranteed, let alone win the trust of the people and green development
