Plain river network area sediment interception and treatment system

Abstract

The invention discloses a plain river network area sediment interception and treatment system which comprises a sediment interception tank arranged at a river channel connection point close to a river mouth, a conveying pipeline, a pneumatic pump, a processing device, an automatic control system, and a river mouth area wetland system which are arranged along a river channel. The automatic control system comprises a data center, a communication module, and a water quality sensor and a mud level sensor which are arranged in the sediment interception tank; the water quality sensor and the mud level sensor are connected with the pneumatic pump through the communication module and the data center; an outlet of the processing device is connected with the river mouth area wetland system; the sediment interception tank is formed by digging the bottom mud of a water body downwards; and a support for supporting the communication module, the water quality sensor, and the mud level sensor is arranged in the sediment interception tank. According to the plain river network area sediment interception and treatment system, the characteristics of fine sand particles, high water content and high fluidity of a plain river network area are utilized to realize automatic and rapid collection, deep treatment and recycling of sand from a river network to the river mouth area, the load of silt and nutritive salt entering a lake is reduced, and the eutrophication risk is reduced.

Description

technical field [0001] The invention belongs to the field of water conservancy engineering and environmental engineering, in particular to a system for collecting and purifying sediment in plain river network areas, which can be applied to river course management and environmental protection. Background technique [0002] The fundamental source of water pollution in lakes and reservoirs is the excessive enrichment of watershed pollutants in lake water and sediments. The erosion of precipitation in the basin or the water used for production and domestic use will cause a large amount of particulate matter to be introduced into the river channel, and then transported by the river channel water into the lake and reservoir to form silt. The organic components in these particulate matter are one of the main causes of water pollution. Therefore, sediment dredging is one of the most common and important means to solve the pollution problems of rivers and lakes. [0003] However, t...
