Embodiment 1

[0037] Such as figure 1 As shown, the novel ecological floating island 1 of the present invention includes an aeration floating device 2, a power unit 4 placed above the aeration floating device 2, a water delivery device 5 connected with the aeration floating device 2, and a water delivery device 5. The nutrient decomposition and absorption device 3 connected with the device 5. Wherein, the aeration floating body device 2 includes an aeration unit 21, and the aeration floating body device 2 includes a plurality of aeration units 21, and the plurality of aeration units 21 are combined in a way of pipeline nesting, thereby forming a waterway passage and gas passage; the power unit 4 includes a solar panel 7, a wind generator 8, and a control cabinet 9 mounted on the top of the aeration floating body device 2, and the power unit 4 provides for the aeration and oxygenation process of the aeration floating body device 2. power. In addition, the floating island formed by a plural...

no. 1 approach

[0040] The following unidirectional square aeration unit is taken as an example to describe the ecological floating island of the present invention in detail. Such as image 3 , Figure 4 with Figure 7 As shown, different from the traditional circular cross section, in the first embodiment, the cross section of the aeration unit 21 is a quadrilateral, such as a rectangle. The aeration unit 21 comprises: a water inlet 22, which is located on one side of the lower part of the aeration unit 21; an air inlet 23, which is located above the water inlet 22, and the air inlet 23 is connected to the fan through a gas distributor; Part 24, which is located above the air inlet 23 and connected to the air inlet 23, and the aeration part 24 is provided with an aerator; the constricted part 25 is located on the upper side of the aeration part 24, and the constricted part The cross-sectional area of ​​25 gradually decreases from bottom to top; the liquid discharge part 26 is located abov...

no. 2 approach

[0047] In the second embodiment, the side of the outer surface provided with the air inlet 23 and the water inlet 22 is called the first outer surface side, and the outer surface side opposite to the first outer surface side is called the second outer surface side. Two outer surface sides. In addition, the same components or parts as those of the first embodiment are denoted by the same reference numerals. Description of the same parts as those of the first embodiment is omitted.

[0048] The difference from the first embodiment is that in the aeration unit 21 of the second embodiment, as Figure 5 , Image 6 with Figure 7 As shown, the structure of the aeration unit 21 is symmetrical with respect to the left and right directions of the paper, and the water inlet 22 and the air inlet 23 are arranged on the outer surface of the lower part of the aeration unit 21 in a manner parallel to the central axis, so that the gas and water The output direction is bidirectional, that ...

Abstract

The invention provides a novel ecological floating island and a water body remediation method by using the ecological floating island. The ecological floating island comprises an aeration floating body device, a power device arranged at the upper part of the aeration floating body device, a water body conveying device connected with the aeration floating body device, and a nutrition decomposing absorbing device connected with the water body conveying device. The aeration floating body device comprises an aeration unit arranged with a contracted neck part. Through the water body remediation method, the rich nutrient substances in the water body can be efficiently absorbed with saved energy by means of green plants; then the improved water is conveyed to the bottom layer or far place of the water body, so as to realize the oxygenation and flow creation of the water body in the zone and the nutrition absorption at the fixed place by light force; the novel ecological floating island is suitable for the large-scale water remediation of closed water domains in lakes, reservoirs, river way, bay, and others.

Description

technical field [0001] The invention relates to a novel ecological floating island and a water restoration method using the ecological floating island. Background technique [0002] With the development of economy, the eutrophication of lakes and other water bodies is a major environmental problem facing the world today. Nutrientization of lakes and reservoirs degrades water quality, induces a "water quality" water shortage crisis, and reduces the comprehensive utilization efficiency of water resources and the ability to guarantee safe water supply. For eutrophic water bodies, various countries and regions adopt different physical, chemical, and biological methods to treat them, and to a certain extent, restore eutrophic water bodies. Research shows that ecological restoration approaches are generally accepted. As one of the in-situ restoration technologies for water bodies, artificial floating islands have significant advantages over other bioremediation technologies. Fl...
