Device for improving circulation condition of water body, and application method thereof

Abstract

The invention discloses a device for improving the circulation condition of a water body. The device comprises a water storage buffer tank body, a water guide pipe, a water feed pipe, a water outlet pipe, a storage battery, a solar panel, a pump, and a main control system mounted on one side of the pump; a groove is arranged in the top of the water storage buffer tank body to serve as a water storage buffer tank, and the pump is mounted above the water storage buffer tank; one end of the pump is connected with the water feed pipe guiding the water body in, and the other end of the pump is connected with the water outlet pipe guiding the water body out; a through hole is arranged in the bottom of the water storage buffer tank body, and the water guide pipe is connected with the through holeto allow water flows to flow in and out of the water storage buffer tank; the solar panel is connected with the storage battery to storage converted electric energy; the main control system is respectively connected with the pump, the storage battery and the solar panel. The device has the advantage that the water body exchange mode of 'from bottom to top', 'from top to bottom' and 'from middle to bottom' is applied to realize exchange among water bodies on different water layers.

Description

technical field [0001] The invention belongs to the technical field of comprehensive utilization of water resources and environmental protection, and in particular relates to a device for improving water circulation and a method for using the same. Background technique [0002] Still water environment refers to water bodies that do not flow or rarely flow. Such water bodies mainly include ponds, reservoirs, lakes, swamps, and relatively closed ocean harbors. Ecosystems in such still water environments are called still water ecosystems. There are several problems in the hydrostatic ecosystem: (1) The stratification of the water body is obvious, and the exchange rate between the surface water and the bottom water body is slow, and even zero exchange occurs, resulting in the temperature, DO and nutrient elements of the water body. Obvious stratification phenomenon; (2) Due to the stratification of the water body and the lack of light at the bottom, the number of algae growing i...

Problems solved by technology

There are several problems in the hydrostatic ecosystem: (1) The stratification of the water body is obvious, and the exchange rate between the surface water and the bottom water body is slow, and even zero exchange occurs, resulting in the temperature, DO and nutrient elements of the water body. Obvious stratification phenomenon; (2) Due to the stratification of the water body and the lack of light at the bottom, the number of algae growing is significantly reduced, and the level of primary productivity is extremely low; (3) The still water environment is not conducive to the diffusion and decomposition of pollutants, and human activities produce Once the waste water, waste residue, etc. enter the waters, their natural digestion and removal capabilities are extremely low, resulting in enrichment in the waters; (4) the digestion rate of organic matter at the bottom of the still water environment is also low, and the content of organic humus increases, which is harmful to benthic organisms. cause harm

[0004] These devices have played a certain role in accelerating the flow of water bodies, but there are also defects in increasing the dissolved oxygen in the water body and promoting the exchange rate of the water body

First of all, when using the drive shaft of the power device to drive the impeller to stir the water body, the energy consumption of the power device is high, and the surface water is stirred, and the bottom water cannot be stirred, so the water body is not stirred sufficiently; secondly, although the upflow type agitator can be used to form Large water flow, but the exchange efficiency between the internal water body and the external water body is not high by using the agitating impeller to drive the device; moreover, the current agitation devices for the water body all consider the water body exchange "from bottom to top", and fail to achieve "from top to bottom", "From the middle to the top", "from the middle to the bottom" and other water body exchange methods
