Plain river water quality improvement system and method

Abstract

The invention discloses a plain river water quality promoting system and a plain river water quality promoting method. Under the action of power provided by a power pump, water body in an inflow river reach is lifted and delivered into a regulating reservoir via a water inlet pipe and a water outlet pipe; after the water level of the regulating reservoir exceeds the crest level of an overflow wall, weir flow is formed and is discharged into an outflow river reach, so that the fluidity of river is enhanced, and the dissolved oxygen level and the water environment capacity of the river are increased; the flow velocity of the river is controlled by a flow control valve; electric power of the power pump is provided in a complementary way by a solar panel, a wind driven generator and an independent power source under the control of a power distribution unit; and part of contaminants in the river can precipitate in the regulating reservoir, and the purpose of removing pollutants can be achieved by regular dredging, thus promoting the water quality of the river. The system and the method have the advantages of being low in operation cost, simple in structure, saving in investment, convenient in operation and remarkable in economical and social benefits, and have significant research and promotion values in the background of high-speed urbanization and energy and water environment crisis.

Description

technical field [0001] The invention belongs to the field of water environment management, and in particular relates to a system and method for improving the water quality of plain rivers. Background technique [0002] The water environment is an important part of the natural ecological environment, but with the acceleration of industrial and agricultural development and urbanization, the deterioration of the water environment has become an indisputable fact. Governments at all levels and their relevant functional departments have also put water environment improvement and restoration on their agenda, and are constantly exploring ways to improve the water environment, especially to restore the water environment of urban rivers in practice. The terrain in the plain area is low and flat, the water flow of the river is poor, the self-purification ability is weak, and it is easy to form stagnant water. In the long run, it will have a very serious negative impact on the local wat...
