River-lake communication method for synchronously realizing urban beheaded river water power improvement and lake water quality safety

Abstract

The invention discloses a river-lake communication method for synchronously realizing urban beheaded river water power improvement and lake water quality safety. The method involves an urban lake, an urban beheaded river, and an urban inland river, and arranging a water pumping point, a water replenishing pump station, a water replenishing pipeline, a water quality purification station, a water replenishing point, a water level regulation and control gate and a drainage pipeline. The water level regulation and control gate is used for isolating the urban beheaded river from the urban lake, the landscape water level of the beheaded river is maintained, the water replenishing pump station extracts a water body of the urban lake, the water quality of the water body is further improved through the water quality purification station, then the urban beheaded river is replenished with water, and the drainage pipeline drains a water body of the beheaded river into other urban inland rivers, so that lake water body pollution caused by backflow to the urban lake is avoided, and improving the urban beheaded river water power and ensuring the urban lake water quality safety are synchronously realized.

Description

technical field [0001] The invention belongs to the technical field of water conservancy engineering, and in particular relates to a river-lake connection method for synchronously realizing the hydrodynamic improvement of urban Duantou River and the water quality safety of lakes. Background technique [0002] With the development of urban construction, many urban inland rivers have been artificially filled to form Duantou River. Due to the lack of water in the upper reaches of the urban Duantou River, coupled with intense human activities, the water body is often seriously polluted, and the problem of black and odor is prominent. When the urban Duantou River is connected to the urban lake, the polluted water and pollutants in the Duantou River will enter the lake, causing lake water pollution and affecting the water quality of the lake. Due to the slow flow of water in the urban lake itself and the tortuous shoreline of the urban lake, it is difficult for the water in the l...

Problems solved by technology

[0009] ③The method of pumping water from urban lakes to replenish urban Duantou River through "pumping station + water supply pipeline" and then returning to urban lakes will still affect the water quality safety of urban lakes
