Embodiment 1

[0031] refer to figure 1 , the arrow found in the figure indicates the direction of water flow. A waterscape project in a residential area in Wuhan uses wind-powered water pumping equipment to extract river water from natural river 1 into the artificial ditches 5 and artificial lake 4 of the residential area, and overflows back to the natural river after circulation. The water quality of the natural river for water intake is Class V all the year round, and it is used as the water source of the community waterscape project; the community waterscape is composed of artificial ditches 5 and artificial lakes 4, and there are emergent plants and floating plants planted in the artificial ditches 5 and artificial lakes 4, and ecological bank slopes are adopted , the water surface area is about 20000m 2 , the water flow path of the artificial ditch is about 2km long; the designed water lifting height of the wind power water lifting equipment is 4m, and the water drop height of the out...

Embodiment 2

[0033] refer to figure 2 , the arrow found in the figure indicates the direction of water flow. 8 fish ponds in Dongxi Lake, Wuhan, with an area of ​​about 4500m 2 , using windmills to lift water to improve the water environment of fish ponds, water lifting windmills 2 lift water from one side of the fish pond through the water pipeline 9 and transport it to the falling water step 6 on the other side, and return it in the form of two-stage falling water, and the water falling height exceeds 1m , increase the supplement of dissolved oxygen in pond water. In order to prevent short flow and dead angle, a diversion dike 7 is set in the fish pond 8 to promote the uniform oxygen concentration of the fish pond water body, and finally make the fish pond water body have a fine flow as a whole, and at the same time, it can be continuously supplemented by the external oxygen source . After nearly two years of operation, the water quality of the fish pond has been significantly improv...

Embodiment 3

[0035] Such as image 3 As shown, the arrows in the figure indicate the direction of water flow. A reservoir in Hubei Province is an important source of drinking water. In order to prevent the nutrient problem of the reservoir bay and ensure the water quality safety of the water source, the water circulation system of the reservoir bay is constructed by using a water-lifting windmill. Descends along the valley, forming an aeration and purification process. The main body of the project is the reservoir bay water circulation system composed of the water lifting windmill 2, the ecological pond 12 and the ecological permeable dam 11. The water-lifting windmill is the power source of the water circulation system of the reservoir bay, and is located on the mountainside of the reservoir bank. The water delivery pipeline 9 is distributed along the ridge, so that the water body in the reservoir bay raised by the windmill can be transported to the ecological pond and the permeable da...

Abstract

The invention relates to a method for driving an external circulation of water to realize aeration oxygenation by utilizing natural wind energy to lift water. Natural wind energy is converted to mechanical energy to drive the external circulation of water in rivers, lakes, reservoirs, ponds or urban landscape water by utilizing an artificial channel and/or a water conveying pipeline and a water lifting windmill arranged thereon, the lifted water after forming a falling head is returned to the rivers, lakes, reservoirs, ponds or urban landscape water in different water-dropping ways, so as to realize the aeration oxygenation to the lakes, reservoirs, ponds or artificial lakes in the urban landscape water, and to promote the flow of the water and increase the dissolved oxygen in the water. By reasonably combining a hydraulic circulation technology and a water-falling aeration oxygenation technology, the wind energy water lifting technology is introduced from the traditional field to the field of the water environment protection, so that the method has characteristics of wide application range, long operation time, low operation time, simplicity in operation management, high technology transferability, good landscape effect, good comprehensive benefit and the like and is suitable for being popularized in regions with poor wind energy resource, mountainous regions and rural areas.

Description

technical field [0001] The invention relates to the fields of water environment improvement, water ecological restoration and clean energy utilization, in particular to a method for using natural wind energy to lift water to drive external circulation of a water body to realize aeration and oxygenation. Background technique [0002] Due to the increased influx of pollutants, surface water bodies, especially closed slow-flowing water bodies that are static or poorly mobile, are more susceptible to pollution. Many rivers and lakes have the characteristics of slow flow, closed water area, small water environment capacity, and low self-purification ability of water body, which are prone to problems such as eutrophication of water body, and it is difficult to effectively guarantee water quality safety and aquatic ecological health. The research on artificial aeration and reoxygenation technology has been carried out abroad for more than 40 years, and occupies an important positio...
