Ecological jellyfish device for water body treatment

Abstract

The invention discloses an ecological 'jellyfish' device for water body treatment. The device mainly comprises a carrier, a floating body controller and an anchoring element, wherein the carrier, the floating body controller and the anchoring element are connected through a standing wire (17); the anchoring element is provided with a fixed button; the carrier mainly comprises a supporting skeleton, a biological carrier layer, a fixed floating body and an inflatable floating body; a rope pipe is installed on the supporting skeleton or inflatable floating body; the inflatable floating body is communicated with one end of an inflatable tube leading to the outside of the water body; the floating body controller is provided with an inflatable tube sleeve which is connected with the inflatable tube; and one end of the standing wire is fixedly connected to the carrier, and the other end of the standing wire successively penetrates through the fixed button and the rope tube and then is connected to the floating body controller. According to the invention, the device is used as a submerged plant growth carrier, so that an eutrophication technical system for ecological treatment of aquatic plants is broadened and expanded; especially, the device is suitable for water quality purification of a deep water body; and the device has the characteristic of modularization operation and has a good industrialized prospect.

Description

Technical field [0001] The invention belongs to the technical field of ecological restoration, and specifically relates to a submerged plant growth carrier for purifying water bodies. Background technique [0002] The frequent occurrence of cyanobacteria caused by the eutrophication of water bodies in our country has caused increasingly prominent water environmental safety issues. For example, in April 2007, cyanobacteria erupted in the lake bay of Lake Taihu, which affected the drinking water of about 2 million people in Wuxi City. The outbreak of cyanobacteria produces peculiar smells and phytotoxins, and can also cause hypoxia in water bodies and death of fish, which endangers the ecological security of the watershed. The ecological methods for eutrophication control in water bodies mainly include ecological floating beds, restoration of aquatic vegetation, and ecological dredging of sediments. [0003] Ecological floating bed is currently the most researched and applied water...

AI Technical Summary

Problems solved by technology

However, the existing ecological floating bed technology is only based on the construction of the growth environment of emergent plants or floating plants, using the surface space of the water body, and the technical system is single

[0004] Aquatic vegetation restoration technology is mainly used in shallow lakes. By simulating natural habitats and combining different emergent plants, floating plants, and submerged plant systems, an aquatic vegetation ecosystem is constructed, and aquatic plants are used to absorb and remove nutrients such as nitrogen and phosphorus. Elements to achieve the purpose of water purification, but this technology has relatively high requirements for the transparency of water bodies. Too low water transparency will affect or even damage the growth of submerged plants. Therefore, vegetation restoration technology is only suitable for shallow lakes or water bodies with high transparency. , the application area is narrow

[0005] The ecological dredging of sediment mainly uses physical methods to remove the surface sediment with nutrient content, emphasizing the subsequent treatment of sediment, which belongs to the ectopic treatment technology of nutrients, and the treatment cost is relatively high

Moreover, the existing sediment dredging or ecological dredging technology system to purify the water body belongs to the "palliative treatment, not the root cause", and it is difficult to fundamentally change the status quo of water eutrophication as a single treatment measure.
