Ecological treatment device for improving oxygen-enriched water body

Abstract

The invention discloses an ecological treatment device for improving an oxygen-enriched water body, and mainly relates to the field of ecological treatment. The ecological treatment device comprises acenter floating island, connecting units and surrounding floating islands, wherein the center floating island and each surrounding floating island respectively comprise a central island body and an aeration pipe; each central island body is provided with an aeration unit; each aeration unit communicates with an aeration pipe; the center floating island and each surrounding floating island are also respectively provided with bioecological treatment enclosure chambers; and the center floating island is connected with each surrounding floating island through a connecting unit. The ecological treatment device provided by the invention has the following beneficial effects: gathering and scattering of a plurality of floating islands can be conveniently realized; the plurality of the floating islands are gathered together to facilitate centralized daily management; meanwhile, after the plurality of the floating islands are gathered together, the floating force of the floating islands is increased, and planting and harvesting operation can be completed in a lake, so the efficiency of planting and harvesting is greatly improved; and the device provided by the invention can be stably fixedat a certain position in the lake, and is less affected by strong wind, heavy rain and large wave.

Description

technical field [0001] The invention relates to the field of ecological management, in particular to an ecological treatment device for improving oxygen-enriched water. Background technique [0002] Because humans discharge a large amount of industrial waste, domestic sewage, and plant nutrients from farmland into lakes, reservoirs, estuaries, bays and other areas, resulting in eutrophication of water bodies, large-scale flooding of duckweed, affected water quality, and large-scale reproduction of duckweed Like a carpet on the surface of the water, a large amount of duckweed absorbs most of the oxygen in the water body, causing aquatic plants and fish to die due to lack of oxygen, and the plants around the water body will also die. Duckweed blocks the river, affects shipping, and hinders drainage and irrigation. , Reduce the output of aquatic products, and bring great economic losses to agriculture, aquaculture, tourism, power generation, etc. [0003] The flood of duckweed...

AI Technical Summary

Problems solved by technology

[0004] In the prior art, the method of ecological floating islands is used to control the eutrophication of water bodies, but there are still many deficiencies in the existing ecological floating islands: 1. It is difficult to implement mechanized operations on the existing ecological floating islands

Multiple ecological floating islands float on the water surface without interfering with each other, and the daily management is completed on the water surface. Nowadays, most of the management operations are done manually, which is acceptable in small-area experiments and demonstrations. If it is promoted on a large scale, frequent, Timely harvesting, manual operation cannot meet the needs and limit its development

[0005] 2. For lakes that use floating islands in a large area, multiple ecological floating islands float on the water surface without interfering with each other, and multiple ecological floating islands will swim freely and irregularly without orientation, making it difficult to locate the floating islands control

Therefore, before planting, it is necessary to use a boat to pull the floating island to the shore and gather it before planting. After planting, the floating island is dragged to the specified position in the lake. This planting method is very inefficient.

[0007] 4. Most of the existing ecological floating islands use large-scale aquatic plants and aquatic vegetables, which are difficult to resist strong winds, heavy rains and waves, and will gather with the wind and flow
