Snail-fish-grass stereo integrated system for controlling eutrophication of water body

Abstract

The invention discloses a snail-fish-grass stereo integrated system for controlling eutrophication of a water body. The snail-fish-grass stereo integrated system for controlling the eutrophication ofthe water body comprises ecological floating beds, a fish farming zone and a benthos zone, wherein multiple sets of the ecological floating beds are equidistantly arranged on a water surface in parallel, and floating green plants are uniformly planted or aquacultured thereon; the fish farming zone and the benthos zone are formed under the water surface at the lower ends of the ecological floatingbeds; a sediment part, a submerged plant part and a snail activity part are arranged in the benthos zone. The snail-fish-grass stereo integrated system purifies and remedies a high-concentration nitrogen-phosphorus water body by a bioremediation technology, is strong in adaptability, high in efficiency of remedying the water body per unit volume, eco-friendly, low in production and maintenance costs and good in remedying effect, increases economic benefits, saves remedying fund, and is beneficial to popularization and application to an eutrophic water zone.

Description

technical field [0001] The invention relates to the technical field of water body purification, in particular to a three-dimensional integration system of snail grass for controlling eutrophication of water body. Background technique [0002] Eutrophication of water body is one of the important signs of extreme deterioration of water quality, and it is also a serious problem in water pollution in the world today. With the development of industry and agriculture, more and more pollutants such as NP are produced in people's life and industrial and agricultural production. Many places enter the water body, causing aquatic plankton, especially algae to multiply, causing serious eutrophication and a series of vicious circles, making some rivers, ponds and reservoirs completely lose their utilization functions due to severe eutrophication, which not only restricts It not only affects the availability of water resources, but also directly affects human health, and restricts the sus...

[0002] Eutrophication of water body is one of the important signs of extreme deterioration of water quality, and it is also a serious problem in water pollution in the world today. With the development of industry and agriculture, more and more pollutants such as NP are produced in people's life and industrial and agricultural production. Many places enter the water body, causing aquatic plankton, especially algae, to multiply, causing serious eutrophication and a series of vicious circles, making some rivers, ponds and reservoirs completely lose their utilization functions due to severe eutrophication, which not only restricts It not only affects the availability of water resources, but also directly affects human health, and restricts the sustainable development of social economy.

Controlling water eutrophication has always been a difficult problem in environmental governance. Although a large amount of funds have been invested in the prevention and control of water bodies such as lakes and reservoirs, the problem of water eutrophication has not been effectively controlled, and water environmental problems remain. exist, and even intensify

Bioremediation technology, especially integrated bioremediation technology, as a technology that takes into account both water environment governance and ecological restoration, has achieved remarkable results in the treatment of eutrophic water pollution in foreign lakes, reservoirs, and park ponds. However, existing Most of the existing bioremediation systems have complex structures and high production costs, which are not conducive to large-scale promotion.
